Not always, but usually yes if your app has user accounts, sync, payments, private data, or any kind of backend.
You probably need an auth provider if you want:
- Sign in / sign up
- Social login (Google, Apple, etc.)
- Password resets / email verification
- Secure token handling
- Session management
- Multi-device login
- Protecting API/backend access
You might not need one if:
- Your app is fully offline
- It’s a simple local-only app
- It has no user accounts
- You’re okay building auth yourself with your own backend
Common options
- Managed auth provider: Auth0, Firebase Auth, Supabase Auth, Cognito
- Faster to ship
- Less security/auth complexity
- Usually the best choice for most apps
- Roll your own
- More control
- More work and more security risk
- Only worth it if you have a strong reason
Rule of thumb
If your app needs users to log in and you want to launch quickly, use an auth provider.
If you want, I can also help you decide which auth provider fits your mobile app based on your stack and features.
