About

The MSAL library for JavaScript enables client-side JavaScript 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-browser package described by the code in this folder uses the @azure/msal-common package as a dependency to enable authentication in JavaScript Single-Page 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 section below.

This is an improvement upon the previous @azure/msal library which will utilize the authorization code flow in the browser. Most features available in the old library will be available in this one, but there are nuances to the authentication flow in both. The @azure/msal-browser package does NOT support the implicit flow.
