Frequently asked questions

Authentication is security-critical code that is easy to get wrong. Built-in auth from a tested template avoids common vulnerabilities like token leakage, insecure password storage, and broken session management.

Yes. Social login (Google, Apple) reduces signup friction by 20-40%. Apple Sign In is required for iOS apps that offer any third-party login option.

Biometric auth (Face ID, fingerprint) is a strong security upgrade that users love. It reduces login friction while increasing security. Goodspeed includes it as a configurable template feature.
