Passkeys are becoming the default answer to a long-standing mobile product problem: users dislike passwords, password reset flows are expensive, and weak credentials create security risk that your app has to absorb later.

For React Native teams, passkeys are not just a new login button. A production implementation touches native platform APIs, your backend authentication model, domain association files, account recovery, QA devices, and store release testing.

Supabase can be a strong backend for React Native apps when you want PostgreSQL, SQL, Row Level Security, Auth, Storage, and Edge Functions. The key React Native detail is session persistence: configure storage and URL handling before building screens on top of the Supabase client.

Facebook Login can still be useful for apps whose audience already uses Meta accounts, but the setup is more sensitive than it used to be. React Native apps need Firebase Auth, a Meta developer app, native URL handling, valid redirect URIs, and special care around iOS Limited Login.

Google Login reduces onboarding friction because many users already have a Google account on their phone. In React Native, the reliable pattern is to let a native Google Sign-In library collect the Google identity token, then pass that token to Firebase Authentication.

Biometric authentication can make a React Native app feel faster and safer, but it should be designed as a local unlock step, not as a replacement for your account system. The device verifies the enrolled fingerprint or face; your app decides what to unlock after that verification succeeds.

Expo's expo-local-authentication package gives React Native apps access to Face ID, Touch ID, Android Biometric Prompt, and device passcode fallback.

Sign in with Apple is a common requirement for React Native apps that offer third-party login options such as Google, Facebook, LinkedIn, or Amazon. It also gives iOS users a privacy-friendly authentication option that works well with Firebase Authentication.
