Microsoft identity platform authentication libraries
The Microsoft identity platform endpoint supports the industry-standard OAuth 2.0 and OpenID Connect 1.0 protocols. The Microsoft Authentication Library (MSAL) is designed to work with the Microsoft identity platform endpoint. It's also possible to use open-source libraries that support OAuth 2.0 and OpenID Connect 1.0.
It's recommended that you use libraries written by protocol domain experts who follow a Security Development Lifecycle (SDL) methodology, like the one followed by Microsoft. If you decide to hand-code for the protocols, you should follow a methodology like Microsoft's SDL and pay close attention to the security considerations in the standards specifications for each protocol.

Types of libraries
Microsoft identity platform endpoint works with two types of libraries:
- Client libraries: Native clients and servers use client libraries to get access tokens for calling a resource, such as Microsoft Graph.
- Server middleware libraries: Web apps use server middleware libraries for user sign-in. Web APIs use server middleware libraries to validate tokens that are sent by native clients or by other servers.
Libraries come in two support categories:
- Microsoft-supported: Microsoft provides fixes for these libraries and has done SDL due diligence on these libraries.
- Compatible: Microsoft has tested these libraries in basic scenarios and confirmed that they work with the Microsoft identity platform endpoint. Microsoft does not provide fixes for these libraries and has not done a review of these libraries. Issues and feature requests should be directed to the library’s open-source project.
For a list of libraries that work with the Microsoft identity platform endpoint, see the next sections in this article.

Microsoft-supported server middleware libraries
Middleware libraries are used to protect Web applications and Web APIs. For web app or Web API written with ASP.NET or ASP.NET Core, the middleware libraries are used by ASP.NET / ASP.NET Core

For any standards-compliant library you can use the Microsoft identity platform endpoint, thus it’s important to know where to go for support.
- For issues and new feature requests in library code, contact the library owner.
- For issues and new feature requests in the service-side protocol implementation, contact Microsoft.
- File a feature request for additional features you would like to see in the protocol.
- Create a support request if you find an issue where the Microsoft identity platform endpoint is not compliant with OAuth 2.0 or OpenID Connect 1.0.
