Microsoft Graph Toolkit MSAL 2.0 Provider

Microsoft Graph Toolkit has been retired

As of August 28, 2026, the Microsoft Graph Toolkit project has been retired and is no longer maintained. This package will receive no further updates.

Thank you to everyone who built with MGT, filed issues, contributed code, and helped others along the way. This project would not have been possible without your support.

The source code remains available under its existing license. If you would like to continue using or maintaining MGT, you are welcome to fork the repository and maintain your own version.

The Microsoft Graph Toolkit (mgt) library is a collection of authentication providers and UI components powered by Microsoft Graph.

The @microsoft/mgt-msal2-provider package exposes the Msal2Provider class which uses msal-browser to sign in users and acquire tokens to use with Microsoft Graph. This provider also supports multiple account logins.

Usage

1. Install the packages

   npm install @microsoft/mgt-element @microsoft/mgt-msal2-provider

2. Initialize the provider in code with Msal2Config

   import {Providers, LoginType} from '@microsoft/mgt-element';
   import {Msal2Provider, PromptType} from '@microsoft/mgt-msal2-provider/dist/es6/exports';
   
   // initialize the auth provider globally
   Providers.globalProvider = new Msal2Provider({
     clientId: 'clientId',
     scopes?: string[],
     authority?: string,
     redirectUri?: string,
     loginType?: LoginType, // LoginType.Popup or LoginType.Redirect (redirect is default)
     prompt?: PromptType, // PromptType.CONSENT, PromptType.LOGIN or PromptType.SELECT_ACCOUNT
     sid?: string, // Session ID
     loginHint?: string,
     domainHint?: string,
     isMultiAccountEnabled?: boolean, // True by default, disables multiple account login if false
     isIncrementalConsentDisabled?: boolean, //Disable incremental consent, true by default
     isMultiAccountEnabled?: boolean // True by default, disables multiple account login if false
     isIncrementalConsentDisabled?: boolean, //Disable incremental consent, true by default
     options?: Configuration // msal js Configuration object
   });

3. Initialize the provider in code with Msal2PublicClientApplicationConfig if a PublicClientApplication is already instantiated. For example, msal-angular instantiates PublicClientApplication on startup.

   import {Providers, LoginType} from '@microsoft/mgt-element';
   import {Msal2Provider, PromptType} from '@microsoft/mgt-msal2-provider/dist/es6/exports';
   import {PublicClientApplication} from '@azure/msal-browser';
   
   // initialize the auth provider globally
   Providers.globalProvider = new Msal2Provider({
     publicClientApplication: PublicClientApplication,
     scopes?: string[],
     authority?: string,
     redirectUri?: string,
     loginType?: LoginType, // LoginType.Popup or LoginType.Redirect (redirect is default)
     prompt?: PromptType, // PromptType.CONSENT, PromptType.LOGIN or PromptType.SELECT_ACCOUNT
     sid?: string, // Session ID
     loginHint?: string,
     domainHint?: string,
     isMultiAccountEnabled?: boolean, // True by default, disables multiple account login if false
     isIncrementalConsentDisabled?: boolean, //Disable incremental consent, true by default
   });

4. Alternatively, initialize the provider in html (only client-id is required):

   <script type="module" src="../node_modules/@microsoft/mgt-msal2-provider/dist/es6/index.js" />
   
   <mgt-msal2-provider client-id="<YOUR_CLIENT_ID>"
                     login-type="redirect/popup"
                     scopes="user.read,people.read"
                     redirect-uri="https://my.redirect/uri"
                     authority=""
                     login-hint=""
                     domain-hint="">
   </mgt-msal2-provider>

Add the incremental-consent-disabled boolean attribute if you wish to disable incremental consent.

1. Multi account login functionality is enabled by default. It can be disabled by adding the boolean attribute multi-account-disabled in the html:

   <script type="module" src="../node_modules/@microsoft/mgt-msal2-provider/dist/es6/index.js" />
   
   <mgt-msal2-provider client-id="<YOUR_CLIENT_ID>"
                     login-type="redirect/popup"
                     scopes="user.read,people.read"
                     redirect-uri="https://my.redirect/uri"
                     authority=""
                     multi-account-disabled>
   </mgt-msal2-provider>

   It can also be enabled/disabled in the Msal2Config object:

   import {Providers, LoginType} from '@microsoft/mgt-element';
   import {Msal2Provider, PromptType} from '@microsoft/mgt-msal2-provider/dist/es6/exports';
   
   // initialize the auth provider globally
   Providers.globalProvider = new Msal2Provider({
     clientId: 'clientId',
     isMultiAccountEnabled?: false
   });

This feature allows multiple accounts to be signed in at the same time, and the user has the ability to switch between the signed in accounts.

See provider usage documentation to learn about how to use the providers with the mgt components, to sign in/sign out, get access tokens, call Microsoft Graph, and more.
