I thought the same thing, I do think it's Apple not liking us NOT using the 2 step verification
Is anyone here having the issue with the 2 step verification on?
Or are we having the same issue because we have this feature off?
I am having the same issue, I log into my Mac, it says the account associated with the Apple ID cannot connect, please re enter password!
So you re enter your password (and it is the correct passward)
It says the account is now locked please reset your password, so you have to reset your password using the security questions
re enter your newly created password.
This should be fine for maybe a day or so.
You will then log onto your mac again after maybe 2 days, same thing again.
AppleID cannot connect using this account, please enter your passward, account gets locked again (even though the password is correct) and so it starts again & again & again & so on.
It's a vicious loop.
So basically I have tried EVERY solution out there to fix this, nothing has worked, nothing is conflicting, internet connection is secure, no one is hacking my account (or pretty sure there are not, bit sad if they are for this long and being unsuccessful) etc etc.
So until this has been fixed, I have removed my AppleID comepletely from my mac.
