Changing apple password
When I change my password it says incorrect and then for a new password it says can’t use the same password. When I put in my passcode to unlock my phone as a secondary it says incorrect passcode.
iPhone 8, iOS 14
When changing the password, you can't reuse the same password for approximately a year.
See the Apple Support article(s) below.
Passcode - If you forgot the passcode for your iPhone or your device is disabled. *
