Can I use Firebase Auth as an authentication provider with Supabase?

Yes. You can use Firebase Auth as an authentication provider with Supabase.

If you have an application using Firebase Auth and want access to the Supabase Platform, use the Firebase Auth integration with Supabase.

If you have an application using Firebase Auth and want a new authentication provider, consider migrating from Firebase Auth to Supabase.

If you are building an application using Firebase Auth and need a standalone Postgres database, you can also use Supabase. In this case, you would set up your own authentication and authorization flows using any provider.

If you are building a new application, consider building it all on Supabase, which includes Auth, a full Postgres database, a Data API (REST and GraphQL), Storage, Realtime, Edge Functions, and more.
