My friend therefore has with him the Google Pixel 3a from his partner. She did back to factory settings and gave it to him before leaving for a semester abroad. However, she forgot to delete her Google account before performing the reset.
The phone works on Android 9. Now when my friend tries to configure the device, he is asked to log into an account that was previously associated with that particular device. Since he does not know the password of his partner's account, he cannot use the device as his own.
Is there a way to fix this without having to ask for the password?
