firebase-authentication

问题 I'm using firebase's pre-build auth UI and which seems very helpful to me reducing a lot of boilerplate code. But I'm facing some limitations. For email registration using prebuild auth UI, there are only the three fields I'm getting ( Email, First and last name, password ) showing the attached image below. But I need to add some extra fields ( Address, Postal code, etc ) and apply some business logic like confirm password , password strength check , etc. I got a solution from another

问题 I am learning Node.JS and I am trying to bring Firebase Auth into my application. With client-side firebase auth, you can just do firebase.auth().currentUser but in node, as the script is not run on the client, but once on the server, you cannot use firebase.auth().currentUser . Is there a way involving sessions or cookies (I think) to get user data and use normal Firebase Auth operations from node just like client side Firebase Auth? (I am using express with Node) 回答1: As you've found there

问题 I developed two different Flutter applications. An Admin Version and another Client Version. I would like to use the same login (auth) and access to Storage for both Apps. 回答1: It's definitely possible to access the same Firebase project from two different apps.

A few things to keep in mind though: Firebase Authentication does not have the concept of an administrator user. It "merely"

问题 I'm setting up my Android app to support email authentication and as part of the task I need to create a dynamic link, which I did in the Firebase console. However, when I tested the link (https://chiaramail.page.link/.well-known/assetlinks.json, I just got back empty data ("[]"). Is there something else that needs to happen? 回答1: I had the same issue.

问题 I am currently looking for the best way to create a user with additional information in a cloud function. The obvious possibility seems to create a trigger which creates a user document: functions.auth.user().onCreate((user) => { /* Create user document in firestore with base information*/ }); And afterwards add the information to the created document. (Handle the promise) But one way or another I don't feel really satisfied with this solution. I would rather do all this stuff in one go. Does

问题 Apart from the existing providers, is it possible to use an additional provider for firebase authentication? I am using Flutter . Any detail explanation will be highly appreciated. 回答1: You can indeed create a custom provider for Firebase Authentication.

The Issue At the moment, the registration screen accepts any email address that is entered, whether or not it is real. For example, if I were to type in gvevg@gverwbgw.com, it would allow the user to register. This is obviously an issue, when it comes to fake accounts and spam etc.
