## What it is
Ueberauth is an Elixir authentication framework for Plug-based web applications, providing a two-phase authentication API inspired by Omniauth. It handles the initial authentication challenge (e.g., OAuth flows) through pluggable community strategies, while leaving per-request authentication to the application or companion libraries like Guardian.

## Use cases
- add GitHub OAuth login to a Phoenix app
- support sign-in with multiple third-party providers
- implement social login in a Plug-based Elixir web app
- build custom authentication strategies for Elixir
- integrate OAuth2 flows with phx.gen.auth
- collect credentials from a login form in a standardized way

## When to choose
- you're building a Phoenix or Plug-based Elixir app and need third-party provider login
- you want a consistent API across many OAuth/OAuth2 strategies
- you need to pair initial authentication with JWT sessions via Guardian

## When to avoid
- you need per-request session authentication handled for you
- you're not using Plug-based Elixir web frameworks
- you need a full turnkey auth solution with user management out of the box
