A lightweight OAuth 2 library that does not depend on any framework. It includes a server with the client credentials, authorization code and refresh token grants, token storage in a database through PDO or in the session, and providers for Google, Microsoft and Keycloak.

Design

  • Interfaces instead of hard-wired classes. Grants and storage sit behind interfaces, so another grant type or a custom storage can be added without touching the core.
  • A shared base for providers. Google, Microsoft and Keycloak all extend the same abstract provider.
  • JWT. Access tokens can also be issued as JWT (firebase/php-jwt).

Built with

  • PHP
  • OAuth 2.0
  • JWT
  • PDO

Type the words anywhere outside the form; case and spaces do not matter. With reduced motion you get a short note instead.
