Is it possible to implement user search function using firebase auth?

I wonder how to do user management using Firebase. I have completed the implementation of the authentication process using firebase auth, but is it developed in a way that additionally stores user information in Firestore to perform a user search function? I wonder if general users can use the user search function using the Firebase auth SDK.

Also, I'm curious about how the user operation on the client-side using Firebase is currently performed.

Solution 1:

You can only register or verify the user using auth service and if you want to search user you have to store user data in real-time or firestore.
