Rails 8 Authentication: Why the New Built-in Generator Matters (and What It Means for Devise)

Rails 8 introduces a built-in authentication generator that creates a secure, convention-based auth system without external dependencies. Unlike previous Rails versions that required manual setup or Devise, this generator produces database models, controllers, and views with session persistence and password reset functionality. While Devise remains relevant for complex features like OAuth and multi-factor authentication, Rails 8's native solution offers a lightweight, maintainable foundation for smaller applications.
