Documentation
Full documentation with examples can be found in the Node.js Quickstart.
You can also see fully working demos using this library in our Auth0 blog:
Installation
The Auth0 Passport strategy is installed with npm.
npm install passport-auth0
Customization
State parameter
The Auth0 Passport strategy enforces the use of the state
parameter in OAuth 2.0 authorization requests and requires session support in Express to be enabled.
If you require the state
parameter to be omitted (which is not recommended), you can suppress it when calling the Auth0 Passport strategy constructor:
const Auth0Strategy = require('passport-auth0');
const strategy = new Auth0Strategy({
state: false
},
function(accessToken, refreshToken, extraParams, profile, done) {
}
);
More on state handling here.
Scopes
If you want to change the scope of the ID token provided, add a scope
property to the authenticate configuration passed when defining the route. These must be OIDC standard scopes. If you need data outside of the standard scopes, you can add custom claims to the token.
app.get(
'/login',
passport.authenticate('auth0', {scope: 'openid email profile'}),
function (req, res) {
res.redirect('/');
}
);
Force a Specific IdP
If you want to force a specific identity provider you can use:
app.get(
'/login/google',
passport.authenticate('auth0', {connection: 'google-oauth2'}),
function (req, res) {
res.redirect('/');
}
);
If you force an identity provider you can also request custom scope from that identity provider:
app.get(
'/login/google',
passport.authenticate('auth0', {
connection: 'google-oauth2',
connection_scope: 'https://www.googleapis.com/auth/analytics, https://www.googleapis.com/auth/contacts.readonly'
}),
function (req, res) {
res.redirect('/');
}
);
Getting Access Tokens
If you want to specify an audience for the returned access_token
you can:
app.get(
'/login',
passport.authenticate('auth0', {audience: 'urn:my-api'}),
function (req, res) {
res.redirect('/');
}
);
Silent Authentication
If you want to check authentication without showing a prompt:
app.get(
'/login',
passport.authenticate('auth0', {prompt: 'none'}),
function (req, res) {
res.redirect('/');
}
);

What is Auth0?
Auth0 helps you to easily:
- implement authentication with multiple identity providers, including social (e.g., Google, Facebook, Microsoft, LinkedIn, GitHub, Twitter, etc), or enterprise (e.g., Windows Azure AD, Google Apps, Active Directory, ADFS, SAML, etc.)
- log in users with username/password databases, passwordless, or multi-factor authentication
- link multiple user accounts together
- generate signed JSON Web Tokens to authorize your API calls and flow the user identity securely
- access demographics and analytics detailing how, when, and where users are logging in
- enrich user profiles from other data sources using customizable JavaScript rules
