## What it is
A PHP library providing a base client for integrating with OAuth 2.0 service providers per RFC 6749. It includes a GenericProvider for Bearer-token providers and supports extension via official and third-party provider packages.

## Use cases
- add 'Sign in with Google' to a PHP web app
- implement OAuth 2.0 login flow with Facebook or GitHub
- connect to any OAuth 2.0 provider using bearer tokens
- build a custom provider client for a proprietary API
- add single sign-on to a PHP application

## When to choose
- you need OAuth 2.0 client functionality in a PHP project
- your provider conforms to the OAuth 2.0 Authorization Framework
- you want a well-maintained, PSR-compliant base with an ecosystem of provider packages

## When to avoid
- you need OAuth 1.0a support
- a dedicated provider client package already covers your provider without needing the base
- you need a full identity/SSO server rather than a client

## Facets
- artifact type: library
- maturity: stable
- function: auth, http-client, sdk
- domain: security, web-development, apis
- platform: php
- tags: oauth2, sso, authentication, composer, psr-compliant
