    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.


    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 v2 Active development 9, 10, 11, 12, 13, 14
    MSAL Angular v1 Active development 6, 7, 8, 9
    MSAL Angular v0 In maintenance 4, 5


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


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

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

    Build and running tests

    If you want to build the library and run all the unit tests, you can do the following.

    First navigate to the root directory of the library(msal-angular) and install the dependencies:

    npm install

    Then use the following command to build the library and run all the unit tests:

    npm run build
    npm run test


    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.
