I have an app that when installed and logged in by firebase, the user will not be able to use your account on another device. In case, if you need to change the device the user will have to ask for the release to a supervisor.
I’m using native Android, firebase auth e firebase Realtime database.
I couldn’t think of an uncomplicated way to do this... Can anyone help me? Thanks in advance!

You can store user session information (such as device serial, date and time of access, etc.) in a Realtime Database node and manually control from this information whenever a user is authenticated in the application. This answer (in English) details an implementation of this approach.
