A Rails authentication system generator that creates customizable, secure authentication code directly in your application.
Authentication Zero is a Ruby gem that generates a complete, production-ready authentication system directly into Rails applications. It solves the problem of implementing secure, customizable authentication without relying on rigid third-party libraries by providing generated code that follows Rails conventions and security best practices.
Rails developers building web or API applications who need a secure, customizable authentication system without the constraints of external libraries.
Developers choose Authentication Zero because it provides full ownership and modification rights over the authentication code, integrates seamlessly with Rails, and includes advanced security features like breach detection, 2FA, and WebAuthn out of the box.

Generates authentication code directly into your Rails app, allowing unlimited customization to fit specific use cases, as emphasized in the philosophy section for complete control.
Includes breach detection for passwords, signed HTTP-only cookies, and sudo mode, following security best practices outlined in the features list to mitigate risks.
Supports cookie-based and token-based auth, 2FA with WebAuthn, passwordless login, and social login via OmniAuth, catering to both web and API applications as detailed in the features.
Provides features for multi-tenant apps, user invitations, and masquerading, making it suitable for complex SaaS projects, with options like --tenantable and --invitable.
Generated code does not update automatically; developers must manually port improvements from the gem, as stated in 'Developer responsibilities,' which can lead to security gaps if neglected.
Implementing features like multi-tenancy requires additional steps, such as adding middleware and scoping models, which the README admits need more customization and can be error-prone.
Exclusively designed for Rails applications, so it cannot be used with other frameworks, limiting its applicability in polyglot or non-Rails environments.
