sign in with apple ID

It is much simpler to have one Apple ID, although you can create up to three Apple ID's using your same device.

If you wish to share purchases amongst your own Apple ID's you can enable Family Sharing

Create a new ID (if necessary) and sign into iCloud using the same Apple ID on another Apple device/computer. You should then be able to sign in.
