Other ways to reset your Mac password

Fortunately, this is far from the only way to reset your Mac password. While none of these are very convenient, Apple has provided a few tools to make changing your Mac password possible. These include the following:

• Use a different admin account to reset your account’s password.
• Reset your Mac password using your Apple ID. Just enter the wrong password a few times and you should see this option show up.
• FileVault can help you recover a password if you’ve set it up. If you haven’t, then you can’t use this option. And even if you have, this is a bit technical, so proceed with caution.
