I need social login on iOS and Android

To add social login on iOS and Android, you typically integrate one or more identity providers like:

• Google
• Apple Sign In (required on iOS if you offer other third-party logins)
• Facebook
• Microsoft / LinkedIn depending on your audience

Common implementation options

1) Use a backend auth platform

Simplest and most scalable option:

• Firebase Authentication
• Auth0
• AWS Cognito
• Supabase Auth

These handle:

• OAuth flows
• token exchange
• user linking
• session management
• secure backend verification

2) Native provider SDKs

If you want full control:

• iOS: AuthenticationServices (Apple), Google/Facebook SDKs
• Android: Google Sign-In, Facebook SDK, etc.
• Then send the provider token to your backend to create your own session

Recommended approach

If you want fast cross-platform support:

• Use Firebase Auth or Auth0
• Implement:
  • Google Sign-In
  • Apple Sign In
  • Facebook Login if needed

Important iOS note

If your app uses Google/Facebook/etc. as sign-in options, Apple App Store policy generally requires you to also offer Sign in with Apple.

Typical flow

1. User taps a social login button
2. App opens provider sign-in
3. Provider returns an auth code / token
4. App sends it to your backend or auth service
5. Backend verifies it
6. User gets logged in and receives your app session/JWT

If you’re using Flutter / React Native / native

I can give you exact setup steps and code for:

• Flutter
• React Native
• Swift (iOS)
• Kotlin (Android)
• Firebase
• Auth0

If you want, I can provide a complete implementation guide for your stack.
