Clearance

Clearance is a Ruby on Rails authentication library that provides flexible, opinionated defaults for email and password-based authentication. It is designed for Rails developers who need a simple, well-tested solution for user sign-in, password reset, and session management, with extensive options for customization, controller/view overrides, and integration into Rails applications. Clearance is especially suitable for teams looking for an easy-to-install, minimal, and extensible authentication solution in their Rails projects.
