Passwordless authentication in Rails can be set up by implementing custom login flows using WebAuthn passkeys and magic links, eliminating the need for third-party gems like Devise. This approach manages user identities and secure sessions directly.

WebAuthn passkey authentication in Rails allows users to sign in using device biometrics or security keys instead of passwords. It integrates with token-based session management to securely persist user sessions and handle identities.

Magic links can be implemented natively in Rails without third-party gems by generating secure, token-based login links sent to users. This custom authentication system handles user identities and session persistence with minimal code.

The best way to add WebAuthn passkeys is implementing a custom passwordless authentication system that handles passkey registration and login. This system manages secure token-based sessions and socialized login flows for web apps.

You do not need third-party gems like Devise to build secure Rails session handling. A custom passwordless authentication system can manage secure token-based session persistence, user identities, and WebAuthn passkeys independently.

Magic links and WebAuthn passkeys provide a passwordless authentication experience that enhances user convenience and security. This custom Rails setup avoids password management vulnerabilities and supports socialized login flows.
