Hi there,
Your Apple ID becomes disabled when someone tries to access your account and the questions answered are incorrect and this happens multiple times.
Apple locks or disables your account and as a result, you can not login to any Apple services.
To fix this issue go iforgot to unlock your account with your password, you use now or reset your password. In the event of multiple unsuccessful attempts, unfortunately, you will have to wait until the next day to try again and reactive your apple account.
I recommend setting up two-factor authentication so when you some tries to log in to your account you are aware where the account login is coming from and verify if it is you or not.
I hope this helps and let me know if you resolve this issue. Have a nice day.
