## What it is
A Ruby gem implementing OAuth 2.0 and 2.1 client functionality, including OpenID Connect (OIDC) support. It handles token requests, grant types (client credentials, authorization code, etc.), and authentication schemes for Ruby applications acting as OAuth clients.

## Use cases
- add oauth2 login to a ruby app
- get access tokens via client credentials flow in ruby
- implement openid connect client in ruby
- exchange authorization code for token in rails
- authenticate against microsoft azure ad from ruby
- refresh oauth tokens in a ruby application

## When to choose
- your Ruby app needs to act as an OAuth 2.0/2.1 client to obtain tokens from providers
- you need OIDC support or multiple grant types and auth schemes in Ruby

## When to avoid
- you need to build an OAuth authorization server or provider in Ruby
- your project is not written in Ruby

## Facets
- artifact type: library
- maturity: active
- function: auth, authorization, http-client
- domain: security, web-development, apis
- platform: ruby, jvm
- tags: oauth2, oauth2-client, oidc, openid-connect, token-management, rubygem
