Android pass firebase auth object to another activity to logout

I am logged in to login to the main activity, but I want to log out to another activity with a button. However, I am unable to pass the object to FirebaseAuth

another activity.

PutParcelable and PutSerializable won't work because I can't control the class itself. General preference only accepts primitive types. Should I get a new instance in a new activity and log out of the user account in a new activity? Does user state persist even if I get a new instance?

here is the code

mAuth = FirebaseAuth.getInstance();
        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    // User is signed in
                    Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
                    Toast.makeText(getApplicationContext(), "You are logged in!!!",
                            Toast.LENGTH_SHORT).show();
                    Intent intent = new Intent(MainActivity.this, CameraActivity.class);

                    startActivity(intent);
                } else {
                    // User is signed out
                    Log.d(TAG, "onAuthStateChanged:signed_out");
                }

            }
        };
