Enter your password incorrectly 3 times.

1. If you see the option to restart and show password reset options, click it to restart your Mac. Then take one of these steps:

• • Sign in with your Apple ID, if asked. You might also be asked to enter the verification code sent to your other devices.
  • Enter your FileVault recovery key, if asked. It's the long string of letters and numbers you received when you turned on FileVault and chose to create a recovery key instead of allowing your iCloud account (Apple ID) to unlock your disk.

1. Select a user that you want to reset the password for, then click Next.
2. Enter your new password information, then click Next. 
3. When the password reset is completed, click Restart.

1. If you see the option to reset using your Apple ID, click it.

• • If your Mac restarts, follow the steps for option 1, above.
  • If your Mac doesn't restart, but immediately asks for your Apple ID, enter that information and click Reset Password.

1. If you're asked to create a new keychain to store the user's passwords, click OK to restart your Mac.
2. If you're asked to select an admin user you know the password for, click “Forgot all passwords?”.
3. If you see a Reset Password window with the option to Deactivate Mac, click Deactivate Mac, then click Deactivate to confirm. This is temporary.
4. Enter your new password information, then click Next.
5. If this window shows multiple user accounts, click the Set Password button next to each account name, then enter the new password information for each account.
6. When the password reset is completed, click Restart.

1. Click the option to reset using your recovery key.
2. Enter your FileVault recovery key. It's the long string of letters and numbers you received when you turned on FileVault and chose to create a recovery key instead of allowing your iCloud account (Apple ID) to unlock your disk.
3. Enter your new password information, then click Reset Password

If you aren't able to use any of these reset options, you may need to reset your MacBook.

*Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps to start up from macOS Recovery:

• Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Select the gear icon labeled Options, then click Continue.
• Intel processor: Turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

Keep this in mind for the following steps.*

If no other solution is successful, you have the option to reset your password by erasing your Mac.

1. Shut down your Mac, then start up from macOS recovery as described previously.
2. When you're asked to select an admin user you know the password for, choose Erase Mac from the Recovery Assistant menu in the menu bar.
3. From the Erase Mac window, click Erase Mac, then click Erase Mac to confirm. 
4. If your Mac restarts to a flashing question mark, press and hold the power button for a few seconds until your Mac turns off.
