title: How to get UID and add user information with Firebase email/password authentication
body: <p>I am using firebase Email/password authentication for both signup and sign in. However during the Sign up process I would like to get the user UID and use that to create a new database in firebase with other user information like Name and phonenumber. I know its easier to get the UID with a login process, however is there a way to do this with signup, assuming sign up has been successful.  I am using android studio.</p>
