On macOS, there is an option to reset a user’s login password using their Apple ID. If you want to keep this backdoor open, the corresponding option must be activated when creating the respective user or in the “Users & Groups” settings. The personal Apple ID then works as a kind of second key if you forget your user password on the Mac.
If you want to take advantage of this opportunity, it is recommended to take a look at the corresponding section in the system settings. According to a letter from a reader, the setting has been disabled for at least some users in connection with one of the latest macOS updates.
After the last Mac update, the “Reset password using iCloud account” feature in the settings was disabled by default for both me and my boyfriend and partner.
Apple’s Mac manual explains the settings
Under macOS, user management is in the hands of the appropriate administrator of a computer. Apple has published an overview and explanation of the associated settings in the online manual for macOS.
Related to this, Apple’s guide to the Mac operating system also notes that the “Allow user to reset password using Apple ID” setting is only available if iCloud is configured on the Mac in question. In addition, the option cannot be used if FileVault encryption is enabled on the computer and it is specified that the affected user can reset their password when they start using their Apple ID.
With regard to the latter connection in particular, it is difficult to say whether it is a general error or a discrepancy in the interaction of the individual Apple services with each other. In any case, it is not a mistake to check the personal Mac user account settings set here.
