Multiple, old Apple IDs keep asking for password on new iPhone
I just bought a new phone and restored a backup I just ran. The backup (and my old phone) had what I assume are some songs that were purchased and authorized by several friends, a long time ago.
When I was setting up the phone from the restore, I signed into my Apple account, but skipped the other 3 that I do not have the passwords for.
Now, the 3 other Apple IDs keep popping up asking me to sign in. It seems to happen more while in iTunes and Messages, but it's not limited to those apps.
I don't know what songs/apps/etc. are tied to these old accounts. I've tried looking online for this, but can't find this specific issue.
Has anyone come across this or know how to stop it?
Thank you
iPhone 7, iOS 12
