@azure/msal-angular is a library that allows Angular applications to authenticate users with Microsoft Identity Platform and obtain tokens to call Microsoft APIs such as Microsoft Graph or any API registered with the Microsoft identity platform.

What are @azure/msal-angular's main functionalities?

User Authentication

This code demonstrates how to set up the MSAL instance in an Angular application to enable user authentication with Microsoft Identity Platform.

import { MsalModule, MsalService, MSAL_INSTANCE } from '@azure/msal-angular';
import { PublicClientApplication } from '@azure/msal-browser';

export function MSALInstanceFactory() {
  return new PublicClientApplication({
    auth: {
      clientId: 'your-client-id',
      authority: 'https://login.microsoftonline.com/your-tenant-id',
      redirectUri: 'http://localhost:4200'
    }
  });
}

@NgModule({
  imports: [
    MsalModule
  ],
  providers: [{
    provide: MSAL_INSTANCE,
    useFactory: MSALInstanceFactory
  }, MsalService]
})
export class AppModule { }

Token Acquisition

This code demonstrates how to log in a user and acquire an access token silently for calling Microsoft Graph API or other APIs.

import { MsalService } from '@azure/msal-angular';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  constructor(private authService: MsalService) {}

  login() {
    this.authService.loginPopup().subscribe(response => {
      console.log('Login successful', response);
    }, error => {
      console.error('Login failed', error);
    });
  }

  getToken() {
    this.authService.acquireTokenSilent({
      scopes: ['user.read']
    }).subscribe(response => {
      console.log('Token acquired', response.accessToken);
    }, error => {
      console.error('Token acquisition failed', error);
    });
  }
}

Guarding Routes

This code demonstrates how to protect routes in an Angular application using MsalGuard to ensure that only authenticated users can access certain routes.

import { MsalGuard } from '@azure/msal-angular';

const routes: Routes = [
  { path: 'profile', component: ProfileComponent, canActivate: [MsalGuard] }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

Microsoft Authentication Library for Angular

About

MSAL for Angular enables Angular web applications to authenticate users using Azure AD work and school accounts (AAD), Microsoft personal accounts (MSA) and social identity providers like Facebook, Google, LinkedIn, Microsoft accounts, etc. through Azure AD B2C service. It also enables your app to get tokens to access Microsoft Cloud services such as Microsoft Graph.

The @azure/msal-angular package described by the code in this folder wraps the @azure/msal-browser package and uses it as a peer dependency to enable authentication in Angular Web Applications without backend servers. This version of the library uses the OAuth 2.0 Authorization Code Flow with PKCE. To read more about this protocol, as well as the differences between implicit flow and authorization code flow, see the description provided by @azure/msal-browser. If you are looking for the version of the library that uses the implicit flow, please see the MSAL Angular v1 library.

The current @azure/msal-angular library improves upon the previous version and utilizes the authorization code flow. Most features available in the old library will be available in this one, but there are nuances to the authentication flow in both. The latest @azure/msal-angular package does NOT support the implicit flow.

Guides

Version Support

At a minimum, @azure/msal-angular will follow the support schedule of the main Angular project. We may continue to support certain versions of Angular that are not under Active or LTS support from the main Angular project on a version-by-version basis, as defined below.

MSAL Angular version	MSAL support status	Supported Angular versions
MSAL Angular v3	Active development	15
MSAL Angular v2	In maintenance	9, 10, 11, 12, 13, 14
MSAL Angular v1	In maintenance	6, 7, 8, 9
MSAL Angular v0	Out of support	4, 5

Prerequisites

Before using @azure/msal-angular, register an application in Azure AD to get your clientId.

Installation

The @azure/msal-angular package is available on NPM:

npm install @azure/msal-browser @azure/msal-angular@latest

Versioning

This library controls how users sign-in and access services. We recommend you always take the latest version of our library in your app when possible. We use semantic versioning so you can control the risk associated with updating your app. As an example, always downloading the latest minor version number (e.g. x.y.x) ensures you get the latest security and feature enhanements but our API surface remains the same. You can always see the latest version and release notes under the Releases tab of GitHub.
