Hi   Rubem Andrade,

Got it — thanks for the heads-up. This sounds like a recent issue with SAP Build Apps (web version) where it's no longer connecting to Firebase, and all users are seeing a "login/password is incorrect" error.

A few things to check and try first:

1. Firebase Authentication Method:

   • Double-check if you're using Email/Password authentication in Firebase.

   • Sometimes Firebase projects have disabled certain auth methods by accident or due to policy updates.

   • Go to: Firebase Console > Authentication > Sign-in Method and ensure Email/Password is enabled.

2. Quota or Billing Issues:

   • Check Firebase usage/billing. If your Firebase project hit its quota or if billing was paused, auth requests may fail.

   • Check: Firebase Console > Usage & billing.

3. Check the Firebase Config in SAP Build:

   • Make sure the Firebase project config (API key, authDomain, etc.) hasn’t changed or been reset.

   • Compare the config in SAP Build Apps under App Settings > Data > Firebase to the one in Firebase Console > Project Settings > General.

4. Recent Changes in Firebase API Rules or SAP Build?

   • Firebase occasionally deprecates APIs, and SAP Build might need an update to support the new rules.

   • If the problem started exactly two days ago, it could be due to a Firebase update or a backend change in SAP Build.

5. Try Logging In Directly to Firebase App:

   • Use the same credentials on a simple test page that uses Firebase Auth directly (or use Postman).

   • This helps rule out whether the issue is with Firebase or SAP Build’s connection to it.

Workaround Suggestions

• Try creating a new Firebase user manually from the Firebase console and logging in with that one.

• Create a new Firebase project and connect SAP Build to it temporarily for testing.

Thanks & Regards

Hello, I had already reviewed the options described above. I even created a new project with just the login screen. the behavior was the same. I believe we have a bug.

Hi

The launch of Firebase Studio (and merging the IDX with it) may have changed things at their end, may be.

[AbdulLatif]

Hi

Hi all,

build service has 4.12.236 build tag which contains the needed change. The corresponding change is also in 4.12.236 web preview.

BR, Timo Kapanen

[RubemAndrade]

Good morning, today we got the same error again. can you check?

[timokapanen]

Hi, could you provide bit more information about this issue. Does it happen with preview app or standalone web build or both? You are using 4.12.236 version, right? In addition would be great to understand if this was working earlier in the week since we provided the patch? We haven't done any other updates since the patch early in the week
