No — you do not need AWS Cognito for mobile sign-in.
You have a few options:
-
Use your own backend
Build sign-in yourself with a database of users, password hashing, token issuance (JWT), etc. -
Use another identity provider
- Firebase Authentication
- Auth0
- Clerk
- Azure AD / Entra ID
- Google / Apple sign-in directly
-
Use Cognito Good choice if you already use AWS and want managed user pools, federation, MFA, and token handling.
When Cognito makes sense
- You want managed auth without building it all yourself
- You need social login or enterprise SSO
- You already host infrastructure on AWS
- You want built-in support for MFA, password reset, account recovery, etc.
When you may not need it
- Your app is simple and uses Apple/Google login only
- You already have an auth provider
- You want more control and are comfortable building auth yourself
Bottom line
Cognito is one option, not a requirement.
If you want, I can also help you choose between Cognito, Firebase, and Auth0 for your mobile app.
