firebase-authentication

问题 I am using FirebaseAuth in my app with Google/Facebook social logins and we allow user to change his email after first login because we have our own backend with user management and we prefill this email in the registration form. It seems that all of a sudden I can't retrieve user's email address from FirebaseUser.getEmail() method. When I try to retrieve email using Facebook/Google login SDKs I can retrieve it so it's not a privacy issue. My email is verified so this should not be problem

问题 Working in Eclipse, & using the provided methods in Firebase' docs, I was able to setup logins for several providers such as Google and Facebook, using the redirect option. I basically click on a button for the provider on my web page, & it takes me to the login screen where I can enter a UID and password (e.g. Google sign-in) However, once I authenticate properly with a valid account, and even if I sign-out, I get logged into the same account, without ever getting the screen prompting to log

问题 I'm currently developing an authentication system with Firebase. I'd like my system to accept email/password, Google and Facebook as sign-up and sign-in methods. So far, so good. Everything works good when the user signs up with each method separately. The problem begins when a user wants to sign up with another method and I need to link the new method to same account that was previously registered by the same user using another method. My examples will mention only the email/password and

问题 Working on a project that uses Firebase for some data storage, and our client requests that the server be implemented with C#.NET. We're setting up REST endpoints on the server so that the client is able to communicate with it for a few purposes (for example, triggering an algorithm to run which can only occur on the server). Firebase recommends we identify users via an ID token, as noted here: https://firebase.google.com/docs/auth/server/verify-id-tokens#verify_id_tokens_using_a_third-party

问题 Auth state changes when a new user is created with email and password. I implement firebase.auth().onAuthStateChanged() observable to watch login state in my app. But it have tool for creating new users that reproduces de issue.
