问题 Is there a way to add a "Full Name" field to the Email/Password authentication on Firebase? (Using Swift) 回答1: You cannot add your own custom field to the Firebase Authentication social providers (Facebook, Google, etc) or email+password. You can of course store such information in your Firebase Database, keyed by the user's ID: users uid_209103 fullName: "Frank van Puffelen" Note that Firebase Authentication already has a displayName property for each user, which may cover your needs. 来源：

问题 I'm struggling with firebase custom claims. I have tested a lot of approaches nothing works. Obviously, I miss something important in the concept itself. So I'm back to the root. This script from the google example should apply customs rule on a newly created user exports.processSignUp = functions.auth.user().onCreate(event => { const user = event.data; // The Firebase user. const customClaims = { param: true, accessLevel: 9 }; // Set custom user claims on this newly created user. return

问题 is there a way in Firebase to limit the number of logins by the same user at the same time, says I want to put a limit of 3 devices at a time for one single account, how can I achieve that ? 回答1: That is not supported by Firebase. The best you can do is keep track of the token auth_time . This is the time of sign-in. You would keep a queue of 3 entries for that. Each time you sign-in a user, send their ID token for verification, add the auth_time to the queue (if it is not there already) and
