firebase-authentication

问题 I'm currently experimenting with Social Media Sign-in and have realised something slightly strange on how these logins are delivered which is stemming from the fact that my workplace, like most offices, blocks 3rd party cookies as a security policy. Google Firebase Authentication uses 3rd party cookies and so if I try to use Firebase, I'm redirected to the Google page (as expected) but when I'm redirected back to the originating webpage after logging in (and Firebase tries to set cookies), I

The problem I'm having is that authUI is not being called. @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate, FIRAuthUIDelegate { var window

问题 Given a email address, is it possbile to get userID of a person? For example, If I have a variable email that has email of the person. Can I get their ID by doing something like String userID = mAuth.DatabaseReference.getuID.(email); Sorry if this a stupid question. Edit: note, I am looking to get ID of a person who is not the current user. So I can't use FirebaseUser user = mAuth.getCurrentUser(); The structure of my database looks like this, so the ID will be stored in database already. I

问题 Please does anyone know how to catch firebase Auth exceptions on flutter and display them, Note: I am not interested in the console ( catcherror((e) print(e)) I need something that is more effective, e.g " user doesn't exist" So that I can then pass it to a string and display it. Been dealing with this for months. Thanks in advance i have tried replacing print(e) with // errorMessage=e.toString(); and then passing it to a function, all efforts have been frutile FirebaseAuth.instance

问题 I am implementing custom (Email) and Facebook login authentication in swift using Firebase. Since, I enabled multiple accounts per email address, a same user using his email as well as his facebook account can sign in to the app. Firebase considers them as two separate users, but I want to merge them as long as the email address is same.
