Use your Apple ID to reset your password
Ideally, you'll have linked your Apple ID to your user account on your Mac during the initial setup, which will make it possible to reset your user password with just a few clicks.
Using your Apple ID to reset your Mac password is an easy process.
After entering the wrong user password three times, you'll be asked if you want to reset the password using your Apple ID, if it's linked to your account. If you don't see the message after your third attempt, your account isn't linked to your Apple ID and you'll need to use the method outlined below.
Here's what to do:
Enter your Apple ID email address and password, and follow the rest of the prompts to create a new password. When you change the password, you'll see a prompt letting you know a new login keychain -- what MacOS uses to store your passwords will be created, but your old keychain will remain saved on your Mac. If you ever remember your old password, you'll be able to unlock the old keychain.
