Hello everyone,

I’m doing final tests for my app and running into a serious issue with authentication.

When I try to sign up, I get this error:

**“Firebase: The supplied auth credential is incorrect, malformed or has expired. (auth/invalid-credential).”**

I’ve already rebuilt the blocks and double-checked the API key, but I still can’t solve the problem.

Could someone with more experience please help me out?

Thanks in advance!

@claudiaaradas Can you confirm you have set up a Realtime Database and are using the credentials from that? Common issue here is users setting up a Firestore database, which we do not support natively.

I created a new project and changed the blocks, and now is working
