firebase-authentication

问题 Using Flutter with plugins firebase_auth and firebase_database. Authenticating with email and password. This is code extract for authentication and handling auth change event.

But, with standard database write rules (auth != null), app throws DatabaseError: Permission denied. It appears that database plugin is not aware of authenticated identity? Any ideas

问题 I tried to create a user using Firebase Auth by sending an email and a password. Now I want to store the first name and last name after a user is created.

问题 Setting up Facebook Authentication with Firebase on Android and getting the following pesky error: com.google.firebase.FirebaseException: An internal error has occurred.

At the moment, even though I seem to able to

问题 I am developing an app under the Ionic Framework and I am also using Firebase. Now, it happens that after a few hours or for a crash of the app or restarting the device, the Authentication is lost. How can I manage to have my user ALWAYS logged in, no matter what happen ? (Like Facebook for example) Here is my Login Controller from the page login.html : .controller('loginController',['$scope', '$firebaseArray', 'CONFIG', '$document', '$state', function($scope, $firebaseArray, CONFIG,

问题 Does Firebase have any trick like { merge: true } to set extra/more custom claims without delete/override the old variables? Step to reproduce: admin.auth().setCustomUserClaims(uid, { a: 'value' }) // Run this first admin.auth().setCustomUserClaims(uid, { b: 'value' }) // Then run this after Result: { b: 'value'} Expected result : { a: 'value', b: 'value' } Or I did something wrong? 回答1: The Firebase documentation for setCustomUserClaims states: customUserClaims : Object The developer claims

问题 I'm building an app that uses firebase auth (and firestore database) but only facebook login. The user only has to login once with my app and from then on when they continue to open the app I check if Auth.auth().currentUser != nil { } And so if there is a logged in user already then i don't make them re-login. But when they want to delete their account from the app the error message pops: Error Domain=FIRAuthErrorDomain Code=17014 "This operation is sensitive and requires recent

问题 I want custom firebase authentication where a user manages the roles of subordinate users. I need guidance on understanding on how to implement my own backend authentication system. Everywhere the documentation keeps mentioning that 'send the username and password to your backend that will generate a custom token'. What is this backend? where do I pursue this?
