icloud password out of date

Hi there, deetroy12!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue with a message that your iCloud password is out of date and I am happy to help out! Since your Apple ID password is going to be the same as your iCloud password, I recommend starting by following the steps to Change your Apple ID password.
Once you have changed the password, check out this article for What to do after you change your Apple ID or password. Then, test to see if you still see the message when you try to sign in. If you still see the error, please let me know where you are trying to sign in.
Have a great day!

If you are using a Windows computer or a non-Apple Mail program, you need to enable 2 Factor Authentication on your Apple ID and create an app specific password to use. If your account won’t allow 2 Factor Authentication, try 2 step verification.
