🐛 [firebase_auth] [firebase_auth/invalid-credential] The supplied auth credential is malformed, has expired, or is not currently supported error after credential-already-in-use exception

ashu2902 commented 11 months ago

Bug report

Describe the bug this is the exact description of the problem:

After the anonymous sign-in, when I try to link the credentials of the anonymous account to PhoneAuth credentials. If the PhoneAuth credential is an already existing account, it throws an exception "credential-already-in-use". in the catch block, I delete the anonymous account and use the signInWithCredentials(), which I receive in the catch block. (since the error is thrown by 'linkWithCredential()', I receive the credentials along with the token). At the third step it started throwing an error: [firebase_auth/invalid-credential] The supplied auth credential is malformed, has expired, or is not currently supported. Also, this is happening only on my iOS devices and it is working perfectly on Android.

Steps to reproduce

Steps to reproduce the behavior:

1.Sign in the user with anonymous provider

Try to link the credentials with phone number of an account that already exists in the firebase authentication
in the catch block of linkWithCredentials, attempt signInWithCredentials and use the credentials provided in the error.credentials
it throws the error: [firebase_auth/invalid-credential] The supplied auth credential is malformed, has expired, or is not currently supported.

Expected behavior

The expected behavior is that the user would be logged in with the credentials received in the catch block.

@nohe427 Could you please take a look at this?

Hi @ashu2902, please provide a complete minimal reproducible code sample in a repo that we can clone so that we can investigate this issue.

Thank you

MirceaX2Mobile commented 11 months ago

I can confirm this. I'm facing the same issue.

Hello @danagbemava-nc @ashu2902 @russellwheatley @darshankawar! So I made a reproducible code. But you will need a Firebase Project with PhoneNumber Auth enabled. I will attach the code bellow. There are 2 textfields one for the phoneNumber, one for the otpCode, each textfield has a button for sendingSMS and sendingOTP.

After that you get credential-already-in-use error and then you use the credential from the error to log into the existing account.

logInToExistingAccount will throw The supplied auth credential is malformed, has expired or is not currently supported

Thanks @MirceaX2Mobile, for the repro.

I can reproduce the issue.

Triage report.

These are the steps I used to reproduce the issue.

Use the code sample from https://github.com/firebase/flutterfire/issues/11841#issuecomment-1806810498
The app will sign in anonymously.
Link the account to a phone number
Logout and restart the app
The app will sign in into a new account
Try to link using the old number that was used in step 3

You will now get the exception [firebase_auth/invalid-credential] The supplied auth credential is malformed, has expired or is not currently supported.

There's another case of this in https://github.com/firebase/flutterfire/issues/11877, although it uses a different sign in method
