Pow is a robust, modular, and extendable authentication and user management library for Elixir, built for Phoenix and Plug-based applications. It provides out-of-the-box user registration, session-based authorization, and optional extensions like password reset, email confirmation, persistent sessions, and invitations.

Use cases

• add user authentication to a Phoenix app
• implement user registration and login with sessions
• manage user accounts and roles in Elixir
• add password reset and email confirmation flows
• support API token authentication in a Plug-based app
• add multitenancy and user roles to a Phoenix application
• enable social login via OAuth providers with PowAssent

When to choose

• you are building a Phoenix or Plug-based Elixir app that needs authentication
• you want a batteries-included, production-proven auth solution with strong defaults
• you need a modular system where each part can be customized or replaced
• you want extensions like password reset, email confirmation, or invitations out of the box

When to avoid

• you are not using Elixir, Phoenix, or Plug
• you need a fully managed hosted authentication service
• you require OAuth multi-provider sign-in without adding the separate PowAssent library
• your app has no user accounts or authentication requirements
