Passwords and Id

Each person should have their own ID. You can set up unique user accounts for each person who uses it on a Mac.

iPhones and iPads are NOT multi-user devices. If one person has more than one device, such as an iPhone and iPad, they should use the same ID on both of their devices.

"Passwords and Id: Does every device you have supposed to have a separate id and password? We have 4 devices , does each one have its own Id and passwords. 2 iPhones and 2 iPads . It is not showing my new iPad Air in my devices"

Apple IDs

No. Not necessarily. You can use a different Apple ID of each, or you could the same Apple ID for all devices, or something in-between.

You are welcome.
