Enable email enumeration protection

[zjamshidi]

Recently received an email from Firebase that recommends enabling email enumeration protection on our projects. The email also mentioned that if we currently utilize fetchSignInMethodsForEmail, our projects will be affected.

We are using FirebaseUI Auth in our iOS project (providing sign-in with Apple, Google, Facebook, email/link). I didn't find anything in your documentation in this regard. What should we do and how we are affected?

We used to have email/password. What would happen to old users trying to login with email/link?

Until this issue is resolved, disable Email enumeration protection (recommended) in Firebase Authentication Settings. This is the same issue as #1171 and #1180 as well.

Any update here?
