Microsoft identity platform code samples

  • Article

These code samples are built and maintained by Microsoft to demonstrate usage of our authentication libraries with the Microsoft identity platform. Common authentication and authorization scenarios are implemented in several application types, development languages, and frameworks.

  • Sign in users to web applications and provide authorized access to protected web APIs.
  • Protect a web API by requiring an access token to perform API operations.

Each code sample includes a README.md file describing how to build the project (if applicable) and run the sample application. Comments in the code help you understand how these libraries are used in the application to perform authentication and authorization by using the identity platform.

Samples and guides

Use the tabs to sort the samples by application type, or your preferred language/framework.

Single-page applications
