New iPhone keeps asking me for Apple ID password for unknown to me apple ids.
I have bought a new iPhone SE via online apple store. During phone initialisation I used my previous iPhone and chose an option to use iCloud backup and now the new phone keeps asking me for Apple ID passwords for a set of unknown to me emails.
My previous iPhone is still working fine using my Apple ID, while new one is logged in with my Apple ID according to settings but still asks for password to other ids.
What the problem is about and how to fix it?
iPhone SE, iOS 13
