passport-azure-ad
Advanced tools
The passport-azure-ad npm package provides authentication and authorization strategies for integrating with Microsoft Azure Active Directory (Azure AD) using the Passport.js framework. It supports various authentication flows including OAuth2, OpenID Connect, and SAML.
OAuth2 Bearer Strategy
This feature allows you to authenticate users using OAuth2 Bearer tokens issued by Azure AD. The code sample demonstrates how to configure and use the BearerStrategy with Passport.js.
const passport = require('passport');
const BearerStrategy = require('passport-azure-ad').BearerStrategy;
const options = {
identityMetadata: 'https://login.microsoftonline.com/{tenant}/v2.0/.well-known/openid-configuration',
clientID: 'your-client-id',
validateIssuer: true,
issuer: 'https://sts.windows.net/{tenant-id}/',
passReqToCallback: false
};
passport.use(new BearerStrategy(options, (token, done) => {
// Token validation logic
done(null, token);
}));OIDC Strategy
This feature allows you to authenticate users using OpenID Connect (OIDC) with Azure AD. The code sample demonstrates how to configure and use the OIDCStrategy with Passport.js.
const passport = require('passport');
const OIDCStrategy = require('passport-azure-ad').OIDCStrategy;
const options = {
identityMetadata: 'https://login.microsoftonline.com/{tenant}/v2.0/.well-known/openid-configuration',
clientID: 'your-client-id',
responseType: 'code id_token',
responseMode: 'form_post',
redirectUrl: 'http://localhost:3000/auth/openid/return',
allowHttpForRedirectUrl: true,
clientSecret: 'your-client-secret',
validateIssuer: true,
passReqToCallback: false
};
passport.use(new OIDCStrategy(options, (iss, sub, profile, accessToken, refreshToken, done) => {
// User profile validation logic
done(null, profile);
}));SAML Strategy
This feature allows you to authenticate users using SAML with Azure AD. The code sample demonstrates how to configure and use the SamlStrategy with Passport.js.
const passport = require('passport');
const SamlStrategy = require('passport-azure-ad').SamlStrategy;
const options = {
identityMetadata: 'https://login.microsoftonline.com/{tenant}/federationmetadata/2007-06/federationmetadata.xml',
loginCallback: 'http://localhost:3000/auth/saml/callback',
issuer: 'your-issuer',
audience: 'your-audience',
cert: 'your-certificate',
privateCert: 'your-private-certificate'
};
passport.use(new SamlStrategy(options, (profile, done) => {
// User profile validation logic
done(null, profile);
}));The passport-google-oauth20 package provides OAuth 2.0 authentication strategy for Google. It allows you to authenticate users using their Google accounts. Compared to passport-azure-ad, it is specific to Google OAuth 2.0 and does not support other authentication flows like SAML or OIDC.
The passport-saml package provides SAML authentication strategy for Passport.js. It allows you to authenticate users using SAML identity providers. Compared to passport-azure-ad, it is more generic and can be used with any SAML identity provider, not just Azure AD.
The passport-oauth2 package provides a generic OAuth 2.0 authentication strategy for Passport.js. It allows you to authenticate users using any OAuth 2.0 provider. Compared to passport-azure-ad, it is more flexible but requires more configuration to work with specific providers like Azure AD.
passport-azure-ad is a collection of Passport Strategies to help you integrate with Azure Active Directory. It includes OpenID Connect, WS-Federation, and SAML-P authentication and authorization. These providers let you integrate your Node app with Microsoft Azure AD so you can use its many features, including web single sign-on (WebSSO), Endpoint Protection with OAuth, and JWT token issuance and validation.
passport-azure-ad has been tested to work with both Microsoft Azure Active Directory and with Microsoft Active Directory Federation Services.
passport-azure-ad has a known security vulnerability affecting versions <1.4.6 and 2.0.0. Please update to >=1.4.6 or >=2.0.1 immediately. For more details, see the security notice.
Current version - 4.0.0
Latest version that support's SAML and WSFED - 2.0.3
Minimum recommended version - 1.4.6
You can find the changes for each version in the change log.
$ npm install passport-azure-ad
This library contains two strategies: OIDCStrategy and BearerStrategy.
OIDCStrategy uses OpenID Connect protocol for web application login purposes. It works in the following manner:
If a user is not logged in, passport sends an authentication request to AAD (Azure Active Directory), and AAD prompts the user for his or her sign-in credentials. On successful authentication, depending on the flow you choose, web application will eventually get an id_token back either directly from the AAD authorization endpoint or by redeeming a code at the AAD token endpoint. Passport then validates the id_token and propagates the claims in id_token back to the verify callback, and let the framework finish the remaining authentication procedure. If the whole process is successful, passport adds the user information to req.user and passes it to the next middleware. In case of error, passport either sends back an unauthorized response or redirects the user to the page you specified (such as homepage or login page).
BearerStrategy uses Bearer Token protocol to protect web resource/api. It works in the following manner:
User sends a request to the protected web api which contains an access_token in either the authorization header or body. Passport extracts and validates the access_token, and propagates the claims in access_token to the verify callback and let the framework finish the remaining authentication procedure. On successful authentication, passport adds the user information to req.user and passes it to the next middleware, which is usually the business logic of the web resource/api. In case of error, passport sends back an unauthorized response.
We support AAD v1, v2 and B2C tenants for both strategies. Please check out section 8 for the samples. You can manage v1 tenants and register applications at https://manage.windowsazure.com. For v2 tenants and applications, you should go to https://aka.ms/appregistrations. For B2C tenants, go to https://manage.windowsazure.com and click 'Manage B2C settings' to register applications and policies.

}
if (!user) {
// "Auto-registration"
users.push(profile);
return done(null, profile);
}
return done(null, user);
});
});
}
));
identityMetadata (Required)
The metadata endpoint provided by the Microsoft Identity Portal that provides the keys and other important information at runtime. Examples:
https://login.microsoftonline.com/your_tenant_name.onmicrosoft.com/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_guid/.well-known/openid-configuration
https://login.microsoftonline.com/common/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_name.onmicrosoft.com/v2.0/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_guid/v2.0/.well-known/openid-configuration
https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration
For B2C, you cannot use v2 common endpoint unless you specify the tenant in passport.authenticate using tenantIdOrName option. See section 4.1.3 for more details.
clientID (Required)
The client ID of your application in AAD (Azure Active Directory)
responseType (Required)
Must be 'code', 'code id_token', 'id_token code' or 'id_token'. For login only flows you can use 'id_token'; if you want access_token, use 'code', 'code id_token' or 'id_token code'.
responseMode (Required)
Must be 'query' or 'form_post'. This is how you get code or id_token back. 'form_post' is recommended for all scenarios.
redirectUrl (Required)
Must be a https url string, unless you set allowHttpForRedirectUrl to true. This is the reply URL registered in AAD for your app. Production environment should always use https for redirectUrl.
passReqToCallback (Conditional)
Required to set to true if using req as the first paramter in the verify function, default value is false. See section 4.1.1.3 for more details.
allowHttpForRedirectUrl (Conditional)
Required to set to true if you want to use http url for redirectUrl like http://localhost:3000.
clientSecret (Conditional)
When responseType is not id_token, we have to provide client credential to redeem the authorization code. This credential could be client secret or client assertion. Non-B2C tenant supports both flows, but B2C tenant only supports client secret flow.
For B2C tenant: clientSecret is required if the responseType is not 'id_token'.
For non-B2C tenant: If responseType is not id_token, developer must provide either clientSecret, or thumbprint and privatePEMKey. We use clientSecret if it is provided; otherwise we use thumbprint and privatePEMKey for client assertion flow.
clientSecret is the app key of your app in AAD. For B2C, the app key sometimes contains \, please replace \ with two \'s in the app key, otherwise \ will be treated as the beginning of an escaping character.
thumbprint (Conditional)
Required if you want to use client assertion flow. thumbprint is the base64url format of the thumbprint (hash value) of the public key.
privatePEMKey (Conditional)
Required if you want to use client assertion flow. privatePEMKey is the private pem key string.
isB2C (Conditional)
Required to set to true if you are using B2C tenant.
validateIssuer (Conditional)
Required to set to false if you don't want to validate issuer, default value is true. We validate the iss claim in id_token against user provided issuer values and the issuer value we get from tenant-specific endpoint. If you use common endpoint for identityMetadata and you want to validate issuer, then you have to either provide issuer, or provide the tenant for each login request using tenantIdOrName option in passport.authenticate (see section 4.1.3 for more details).
issuer (Conditional)
This can be a string or an array of strings. See validateIssuer for the situation that requires issuer.
jweKeyStore (Conditional)
This option is required if you want to accept and decrypt id_token in JWE Compact Serialization format. See section 4.1.1.4 for more details.
useCookieInsteadOfSession (Conditional)
Passport-azure-ad saves state and nonce in session by default for validation purpose. Consider regenerating the session
after authentication to prevent session fixation attacks when using the default. If useCookieInsteadOfSession is set to
true, passport-azure-ad will encrypt the state/nonce and put them into cookie instead. This is helpful when we want to be
completely session-free, in other words, when you use { session: false } option in passport.authenticate function.
If useCookieInsteadOfSession is set to true, you must provide cookieEncryptionKeys for cookie encryption and decryption.
cookieSameSite (Conditional)
If set to true, Passport will add the Same-Site: None header to cookies set by the lib, specifically to validate state and nonce.
cookieEncryptionKeys (Conditional)
If useCookieInsteadOfSession is set to true, you must provide cookieEncryptionKeys. It is an array of the following format: [ {key: '...', 'iv': '...' }, {key: '...', 'iv': '...' }, ...]. key could be any string of length 32, and iv could be any string of length 12. We always use the first set of key/iv to encrypt cookie, but we try all the key/iv to decrypt cookie.
This is helpful if you want to do key rollover. The encryption/decryption algorithm we use is aes-256-gcm. You can limit the cookie amount and expiration using nonceLifetime and nonceMaxAmount options.
scope (Optional)
List of scope values besides openid indicating the required scope of the access token for accessing the requested resource. For example, ['email', 'profile']. If you need refresh_token for v2 endpoint, then you have to include the 'offline_access' scope.
loggingLevel (Optional)
Logging level. 'info', 'warn' or 'error'.
loggingNoPII (Optional)
If this is set to true, no personal information such as tokens and claims will be logged. The default value is true.
nonceLifetime (Optional)
The lifetime of nonce in session in seconds. The default value is 3600 seconds.
nonceMaxAmount (Optional)
The max amount of nonce you want to keep in session or cookies. The default number is 10. The oldest nonce(s) will be removed if the total number exceeds. (You can keep this number very small because nonce will be removed from session or cookies after validation. This mainly handles the case when user opens more than one login tabs at once and wants to go back to the first login page to type user credentials. Each login tab results in a nonce in session or cookie, so we only honor the most recent nonceMaxAmount many login tabs.)
clockSkew (Optional)
This value is the clock skew (in seconds) allowed in token validation. It must be a positive integer. The default value is 300 seconds.
If you set passReqToCallback option to false, you can use one of the following signatures for the verify callback
function(iss, sub, profile, jwtClaims, access_token, refresh_token, params, done)
function(iss, sub, profile, access_token, refresh_token, params, done)
function(iss, sub, profile, access_token, refresh_token, done)
function(iss, sub, profile, done)
function(iss, sub, done)
function(profile, done)
If you set passReqToCallback option to true, you can use one of the following signatures for the verify callback
function(req, iss, sub, profile, jwtClaims, access_token, refresh_token, params, done)
function(req, iss, sub, profile, access_token, refresh_token, params, done)
function(req, iss, sub, profile, access_token, refresh_token, done)
function(req, iss, sub, profile, done)
function(req, iss, sub, done)
function(req, profile, done)
We support encrypted id_token in JWE Compact Serialization format.
The key encryption algorithms supported are:
RSA1_5, RSA-OAEP, A128KW, A256KW, dir.
The content encryption algorithms supported are:
A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, A128GCM, and A256GCM.
In order to decrypt the id_token, keys have to be provided in JWK format using jweKeyStore option. We will first
try the key with the corresponding kid. If decryption fails, we will try every possible key in jweKeyStore.
The following is an example of jweKeyStore:
jweKeyStore: [
{ 'kid': 'sym_key_256', 'kty': 'oct', 'k': 'WIVds2iwJPwNhgUgwZXmn/46Ql1EkiL+M+QqDRdQURE=' },

passport.authenticate to protect routesTo complete the sample, provide a route that corresponds to the path configuration parameter that is sent to the strategy:
app.get('/login',
passport.authenticate('azuread-openidconnect', { failureRedirect: '/' }),
function(req, res) {
log.info('Login was called in the Sample');
res.redirect('/');
});
function regenerateSessionAfterAuthentication(req, res, next) {
var passportInstance = req.session.passport;
return req.session.regenerate(function (err){
if (err) {
return next(err);
}
req.session.passport = passportInstance;
return req.session.save(next);
});
}
// POST /auth/openid/return
// Use passport.authenticate() as route middleware to authenticate the
// request. If authentication fails, the user will be redirected back to the
// home page. Otherwise, the primary route function function will be called,
// which, in this example, will redirect the user to the home page.
app.post('/auth/openid/return',
passport.authenticate('azuread-openidconnect', { failureRedirect: '/' }),
regenerateSessionAfterAuthentication,
function(req, res) {
res.redirect('/');
});
app.get('/logout', function(req, res){
req.logout();
res.redirect('/');
});
passport.authenticatefailureRedirect: the url redirected to when the authentication fails
session: if you don't want a persistent login session, you can use session: false. The default value is true.
customState: if you want to use a custom state value instead of a random generated one
resourceURL: if you need access_token for some resource. Note this option is only for v1 endpoint and code, code id_token, id_token code flow. For v2 endpoint, resource is considered as a scope, so it should be specified in the scope field when you create
the strategy.
tenantIdOrName: if you want to specify the tenant to use for this request. You can use the tenant guid or tenant name (like 'contoso.onmicrosoft.com'). Note:
identityMetadata, otherwise this option will be ignored. We will fetch and use the metadata from the tenant you specify for this request.tenantIdOrName value in session before sending the authentication request. When we receive a request containing code or id_token, we retrieve the saved tenantIdOrName value from session and use that value.tenantIdOrName must be used for every login request.domain_hint: if you want to specify the domain that the user should use to sign in. This option is not supported for B2C tenant.
login_hint: if you want to prefill the username with a given value in the login page. The value should be the upn of a user, not the email (most times they are the same though).
prompt: v1 and v2 endpoint support login, consent and admin_consent; B2C endpoint only supports login.
response: this is required if you want to use cookie instead of session to save state/nonce. See section 4.1.4.
Example:
passport.authenticate('azuread-openidconnect', { failureRedirect: '/', session: false, customState: 'my_state', resourceURL: 'https://graph.microsoft.com/mail.send'});
passport.authenticate('azuread-openidconnect', { tenantIdOrName: 'contoso.onmicrosoft.com' });
Passport framework uses session to keep a persistent login session. As a plug in, we also use session to store state and nonce by default, regardless whether you use { session: false } option in passport.authenticate or not. To be completely session free, you must configure passport-azure-ad to create state/nonce cookie instead of saving them in session. Please follow the following example:
passport.use(new OIDCStrategy({
...
nonceLifetime: 600, // state/nonce cookie expiration in seconds
nonceMaxAmount: 5, // max amount of state/nonce cookie you want to keep (cookie is deleted after validation so this can be very small)
useCookieInsteadOfSession: true, // use cookie, not session
cookieEncryptionKeys: [ { key: '12345678901234567890123456789012', 'iv': '123456789012' }], // encrypt/decrypt key and iv, see `cookieEncryptionKeys` instruction in section 4.1.1.2
},
// any supported verify callback
function(iss, sub, profile, accessToken, refreshToken, done) {
...
});
app.get('/login', passport.authenticate('azuread-openidconnect', { session: false }));
// We pass these options in to the ODICBearerStrategy.

log.info('User was added automatically as they were new. Their oid is: ', token.oid);
users.push(token);
owner = token.oid;
return done(null, token);
}
owner = token.oid;
return done(null, user, token);
});
}
);
identityMetadata (Required)
The metadata endpoint provided by the Microsoft Identity Portal that provides the keys and other important information at runtime. Examples:
https://login.microsoftonline.com/your_tenant_name.onmicrosoft.com/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_guid/.well-known/openid-configuration
https://login.microsoftonline.com/common/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_name.onmicrosoft.com/v2.0/.well-known/openid-configuration
https://login.microsoftonline.com/your_tenant_guid/v2.0/.well-known/openid-configuration
https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration
For B2C, you can only use v2 tenant-specific endpoint.
clientID (Required)
The client ID of your application in AAD (Azure Active Directory)
passReqToCallback (Conditional)
Required to set to true if using req as the first paramter in the verify function, default value is false. See section 4.2.1.3 for more details.
isB2C (Conditional)
Required to set to true if you are using B2C tenant.
policyName (Conditional)
Required if you are using B2C tenant. It is a string starting with 'B2C_1_' (case insensitive).
validateIssuer (Conditional)
Required to set to false if you don't want to validate issuer, default value is true. We validate the iss claim in id_token against user provided issuer values and the issuer value we get from tenant-specific endpoint. If you use common endpoint for identityMetadata and you want to validate issuer, then you must provide issuer, or provide tenantIdOrName in passport.authenticate.
issuer (Conditional)
This can be a string or an array of strings. See validateIssuer for the situation that requires issuer.
allowMultiAudiencesInToken (Conditional)
Required if you allow access_token whose aud claim contains multiple values.
scope (Optional)
This value is an array of scopes you accept. If this value is provided, we will check if the token contains one of these accepted scopes. If this value is not provided, we won't check token scopes.
audience (Optional)
Must be a string or an array of strings. We invalidate the aud claim in access_token against audience. The default value for audience is clientID.
loggingLevel (Optional)
Logging level. 'info', 'warn' or 'error'.
loggingNoPII (Optional)
If this is set to true, no personal information such as tokens and claims will be logged. The default value is true.
clockSkew (Optional)
This value is the clock skew (in seconds) allowed in token validation. It must be a positive integer. The default value is 300 seconds.
proxy (optional)
This value is the proxy settings object: { port: 'proxyport', host: 'proxyhost', protocol: 'http' }
If you set passReqToCallback option to false, you can use the following verify callback
function(token, done)
If you set passReqToCallback option to true, you can use the following verify callback
function(req, token, done)
passport.authenticate to protect resources or APIsIn the following example, we are using passport to protect '/api/tasks'. User sends a GET request to '/api/tasks' with access_token in authorization header or body. Passport validates the access_token, adds the related claims from access_token to req.user, and passes the request to listTasks middleware. The listTasks middleware can then read the user information in req.user and list all the tasks related to this user. Note that we do authentication every time, so we don't need to keep this user in session, and this can be achieved by using session: false option.
server.get('/api/tasks', passport.authenticate('oauth-bearer', { session: false }), listTasks);
passport.authenticatesession: if you don't want a persistent login session, you can use session: false. The default value is true.
tenantIdOrName: if you use common endpoint, you can use this option to dynamically provide the tenant.
Example:
passport.authenticate('oauth-bearer', { session: false });
In the library root folder, type the following command to install the dependency packages:
$ npm install
Type the following command to run tests:
$ npm test
First you need to register one application in v1 tenant, one in v2 tenant and one in B2C tenant.
For the v2 application, you should register it at https://apps.dev.microsoft.com/ instead of Azure Portal.
For the B2C application, create policies named 'B2C_1_signin', 'B2C_1_signup'. For each policy, select 'Local Account' as the identity provider, and select the following:
'B2C_1_signup':
Sign-up attributes: 'Display Name', 'Email Address', 'Given Name', 'Surname'
Application claims: 'Display Name', Email Addresses', 'Given Name', 'Identity Provider', 'Surname', 'Users Object ID'
'B2C_1_signin':
You will also need to click the 'Run now' button in the 'B2C_1_signup' blade to create an user.
For B2C application, you will also need to create at least one scope and provide it to test parameters. See how to create scope for B2C access token. In the bearer_b2c_test, We will use OIDCStrategy to get a B2C
access token for the scope, and use BearerStrategy to validate the scope. Note for scope we use the full url in
b2c_params.scopeForOIDC but only the name in b2c_params.scopeForBearer. For example,
b2c_params.scopeForOIDC=['https://sijun1b2c.onmicrosoft.com/oidc-b2c/read'] and b2c_params.scopeForBearer=['read'].
Open test/End_to_end_test/script.js, set is_test_parameters_completed parameter to true. For test_parameters variable, fill in the tenant id/client id/client secret of your applications, and the username/password of your application user.
For thumbprint and privatePEMKey parameters, you need to specify a certificate for your app and register the public key in Azure Active Directory. thumbprint is the base64url format of the thumbprint of the public key, and privatePEMKey is the private pem key string. For a v1 tenant, you can follow this post to generate a certificate and register the public key. For a v2 tenant, you can go to your application page in the v2 portal and click Generate New Key Pair. A certificate will be generated for you to download. The corresponding public key is automatically registered in this case.
Type the following commands to run the tests:
$ cd test/End_to_end_test
$ npm install
$ npm install grunt -g
$ grunt run_tests_with_e2e
Tests will run automatically and in the terminal you can see how many tests are passing/failing. More details can be found here.
By default, passport-azure-ad logging does not capture or log any PII or OII. The library allows app developers to turn this on by configuring loggingNoPII in the config options. By turning on PII or OII, the app takes responsibility for safely handling highly-sensitive data and complying with any regulatory requirements.
//PII or OII logging disabled. Default Logger does not capture any PII or OII.
var options = {
...
loggingNoPII: true,
...
};
//PII or OII logging enabled
var options = {
...
loggingNoPII: false,
...
};
