fetchSignInMethodsForEmail returning nil when email has providers associated.
#11810

As an FYI; this API appears to work on our emulators but not when using Firebase server. |
|
Hmm, I've just confirmed that the corresponding sample at https://github.com/firebase/firebase-ios-sdk/blob/master/FirebaseAuth/Tests/Sample/Sample/MainViewController%2BUser.m#L113 works for me, so not sure what is going on. We may need a full repro.

Related: firebase/firebaseui-web#1040 (same issue on the web; seems to affect new projects). Has something changed with the backend https://identitytoolkit.googleapis.com/v1/accounts:createAuthUri recently? |

We have another issue related to this problem. This user reports that the issue can be replicated by enabling "Create multiple accounts for each identity provider". However, I was able to replicate across web, android & ios without it enabled. It appears to be a Firebase server issue so not sure if this is in the right repository, and apologies for flagging here. I've created a quick web script to demonstrate. It requires:
As a sanity check, I've also included sign-in. import { initializeApp } from 'firebase/app';
import {
getAuth,
fetchSignInMethodsForEmail,
signInWithEmailAndPassword,
onAuthStateChanged,
} from 'firebase/auth';
var config = {
//INSERT FIREBASE CONFIG
};
var app = initializeApp(config);
const auth = getAuth(app);
const email = 'INSERT EMAIL ADDRESS';
const password = 'INSERT PASSWORD';
onAuthStateChanged(auth, async (user) => {
if (user) {
console.log('user', user);
// ...
} else {
console.log('Signing in.....');
let userCred = await signInWithEmailAndPassword(
auth,
email,
password
);
console.log('userCred', userCred);
}
});
const button = document.getElementById('button-id');
// Attach an event listener to the button
button.addEventListener('click', async () => {
fetchSignInMethodsForEmail(auth, email)
.then((signInMethods) => {
// This produces an empty array
console.log('signInMethods', signInMethods);
})
.catch((error) => {
console.log('error', error);
});
}); |

thanks for the invsestigation @russellwheatley. Backend issue tracked internally at b/301111687 |

I have the same issue with the javascript web sdk, except that the promise resolves to [] instead of giving me the correct signinmethods. I need to use the feature to decide whether I should link a currently signed in, anonymous account with a new email link sign in method or if I should just sign in the existing account and throw away the old account. Would be very glad if this were to be fixed. |

@paulb777 Hello, can we downgrade to a specific version to make it work ? It blocks our authentication logic |
|
@tolotrasamuel The issue is on the server side so changing the SDK will not help. |
|
@paulb777 Hey, has there been any movement on this issue? It seems that implementing proper email/password auth flows has been broken for new projects for the past couple of weeks |
|
@sgb-io There is ongoing progress. Hopefully, we can share something soon. |
|
See https://cloud.google.com/identity-platform/docs/admin/email-enumeration-protection for context and a possible workaround |
|
I can confirm once I disabled email enumeration protection via this API call: The provider list returned. I would say that the project I am testing against was created before the date specified this feature would be default enabled - September 15, 2023. I am going to put a note in the Firebase Flutter documentation here: https://firebase.google.com/docs/auth/flutter/email-link-auth#differentiating_emailpassword_from_email_link regarding this protection and put the PR up for review. |

I believe we can close this issue @morganchen12 |

API deprecation is in progress at #12081 |
