What can a user use in macOS Recovery to reset their password if their Mac has FileVault turned on?

In macOS Recovery, when a user's Mac has FileVault enabled, they can utilize the personal recovery key to reset their password. FileVault encrypts the data on the disk, and the personal recovery key serves as a safeguard allowing users to regain access to their encrypted data if they forget their password. This key is a unique alphanumeric string that users should store in a safe place when they enable FileVault.

The personal recovery key is specifically designed for situations like this, where access is necessary without the original password. While Apple IDs can be linked to user accounts for password resets, they are not a direct method available within macOS Recovery for FileVault-protected devices. The professional recovery key is not commonly utilized by end-users and pertains more to enterprise management scenarios, while security questions typically apply to user account recovery processes, not specifically for recovering FileVault access. Thus, the personal recovery key stands as the appropriate and effective method for password reset in this context.
