Firebase Auth Anonymouse Registration/Login for Android java

Question

I want to make firebase auth anonymous login for my application. I store this information in firebase realtime. FirebaseAuth.getInstance().signOut(); when this person logs out of their account Is it possible to get it back into the same account? I don't want to create a new account, I want to make it login to anonymous account. I am saving uuid during registration. How can I do that?

Once a user signs out of an anonymous account there is no way to regain the same UID for that user. If this is a requirement for your app, you will have to implement a custom provider somehow tying the UID of your users to the app instance.
