Unfamiliar devices logging into my Apple account
Unfamiliar devices keep logging into my Apple account through an iMac. I keep changing my password yet they continue to get in. How can I solve this issue?
Don't you have two-factor authentication for your Apple ID? If not, then please activate 2FA. Else are you sharing your Apple ID with others? If yes, please avoid it.
With 2FA and not sharing your Apple ID & password, no one can ever log into your Apple ID on your Mac without your knowledge.
