Firebase Auth Convert an anonymous account to a permanent account Error

[davidarice]

Description

I'm trying to convert an anonymous user to a permanent user.

// link anonymous user to new credential let credential = EmailAuthProvider.credential(withEmail: email, password: password) try await auth.currentUser?.link(with: credential)

I would expect to see that the user has been converted to a permanent user, but I get an error: Error Domain=FIRAuthErrorDomain Code=17006 "Please verify the new email before changing email." UserInfo={NSLocalizedDescription=Please verify the new email before changing email., FIRAuthErrorUserInfoNameKey=ERROR_OPERATION_NOT_ALLOWED}

Reproducing the issue

// link anonymous user to new credential let credential = EmailAuthProvider.credential(withEmail: email, password: password) try await auth.currentUser?.link(with: credential)

I've used both the async/await functionality as well as the callback. I've also tried updating the user's email using updateEmail(to: <String>) with the same error, though I shouldn't need to do this.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reporting, @davidarice. Per checking, it seems that the error is caused by the sign-in provider not being enabled in the Firebase project. With this, could you confirm if the Anonymous and Email/Password provider is enabled in your console?

[davidarice]

I can confirm that both Anonymous and Email/Password provider are enabled.

This issue is confirmed on recently created projects. The backend issue is internally tracked at b/302725971

[paulb777]

See https://cloud.google.com/identity-platform/docs/admin/email-enumeration-protection for context and a possible workaround

[davidarice]

Thanks, Paul. I’ll disable email enumeration and see if that helps.

EDIT: I've confirmed that after disabling email enumeration in google cloud console I'm now able to convert from anonymous to a permanent account using email provider.
