I'm working on an Android application that uses Firebase Authentication, for the signup I intent to store the username, email and password. Is it possible to store the username in the Firebase authentication file instead of having to create a db? For instance is it possible to avoid creating a Firestore user database by just capturing their information through the Firebase Authentication and storing it along with the email and password?
I tried sending the username to Firebase Authentication along with the email and password but got an error.
