I must be “slow on the up-take, because l have always thought having one Apple ID was all that was needed… signing on to iCloud ( the new one) I read that I can have 5 email addresses . When I chang -ed my password for my Apple ID, it showed email address@.com.! I wrote it the way I alway do with the email address @google.com. From now on, I guess 5 “@icloud.com(s) are all I need, but which one will be my Apple IDi, the first one that was my AppleID all along’, but has “iCloud.Com at the end?
