pow-auth/pow

Pow is an authentication library for Elixir and Phoenix applications, providing a modular framework for managing user sessions, credentials, and account workflows. It offers a suite of extensions including email confirmation, password resets, persistent sessions, and user invitations, each with dedicated Ecto schemas and Phoenix controllers. The system also includes Mix tasks to automate the generation of migrations, templates, and configuration, streamlining the integration of authentication features into web applications.
