The Microsoft Authentication Library for JavaScript enables client-side JavaScript web applications, running in a web browser, to authenticate users using Azure AD for 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 lib folder contains the source code for all of our libraries. You will also find all the details about installing the libraries, in their respective README.md.

We ship a number of different packages which are meant for different platforms. You can see the relationship between packages and different authentication flows they implement below.

The samples folder contains sample applications for our libaries. A complete list of samples can be found in the respective package folders or on our wiki.

All of our libraries follow semantic versioning. We recommend using the latest version of each libary to ensure you have the latest security patches and bug fixes.

Please check the roadmap to see what we are working on and what we have planned for future releases.
