How do I return a list of users if I use the Firebase simple username & password authentication
(7 answers)
Closed 5 years ago.
How can I retrieve the list of users from Firebase Authentication? I can get the 'current' user but that's it. Or do I have to add users to database first and get the list from there?
If you have a nodejs project, use the firebase auth:export to export users from Firebase Auth. Users can be exported in csv or json format:
firebase auth:export users.json --format=json --project projectname
It's not possible to retrieve a list of users from Firebase Authentication.
The explanation is in this thread
The only way to do that is to save the user to the database once they are registered.

Just you have to add a role node in the firebase database saving the user's unique id like uid seprated by it their role.
"role" : {

"uid_2" : "manger" }

How to get userID by user Email Firebase android?
(6 answers)

I am trying to know if a user exists in Firebase (Email/Password Authentication) y only knowing the display name.
I am doing this is Android (Java).
Thank you so much!
There is no built-in support in Firebase Authentication to look up users by their display name. Given the loose definition of the meaning of the display name, it would be of limited use. Display names can't be required to be unique, since it's just a value that says how the user wants to be addressed: "When you show something from/to me, show this name next to it".
Many developers end up allowing their users to pick a username/nickname, which they then do require to be unique. If that approach make sense for your use-case too, I recommend reading some of these questions about how to accomplish this with the use of the Firebase Realtime Database:
Firebase android : make username unique
Enforcing unique usernames with Firebase simplelogin
Firebase query if child of child contains a value (a more general explanation of uniqueness in the Firebase Realtime Database)
How do you prevent duplicate user properties in Firebase?
I done all the implementation of Firebase Invites in my android app through Firebase invites.

- How is validation done for user who has already installed the app?
If the validation is not done from Firebase end then is there any way to do it??
Do I have to generate my own reference code or will it be generated by firebase?
See documentation here :- https://firebase.google.com/docs/invites/android
You will get appinvite id which is auto generated by the firebase and its upto you,how you use it.
You can save this id in the database such that it will saved in both profile
,invited person profile and the person who invites such as you will access these ids easily inside the database.
Or put id as a key and put both person proile id inside it.
Hope this will help!!.

How do I return a list of users if I use the Firebase simple username & password authentication

I am storing user's display name in Firebase Auth. Fetching from Firebase Auth is simple when the same user is logged in. But, when another user is logged in, how do I fetch an account's display name when I have their unique UID (User ID).
One solution is when you register a user add his details in database also
Example
Once you are under createUserWithEmailandPassword()
DatabaseReference db=FirebaseDatabase.getInstance().getReference();
DatabaseReference users = db.child("Users").child(mAuth.getCurrentUser().getUid());
users.child("Name").setValue("<NAME>");
Now when the user signs into your database retrieve the Name from the database from child Users
You can't get the name, or any other details of a user that is not currently signed in using FirebaseAuth.
Instead, you must create a node in your database where you store the name, and any other necessary details by querying the database.
I'm really curious to know how you have the UID of any other user without doing this.

How do you include a username when storing email and password using Firebase (BaaS) in an Android app?

I started using Google's Firebase because, as you know, Parse is shutting down :-/
but I'm so lost in it.
I'm using registration by email / password and it is all good, but I want to add a simple username (not an email address) to this.
Could someone help me, please?
You can add the username field on the input form on your client and then, after the standard email / password authentication process is completed, use Firebase Database to store the user informations in the path /users/<uid>, adding the username and all the other fields you need.
