How do I reset password on Mac air m1

Greetings Rlj6912,

Welcome to Apple Support Communities. You can find the guidance needed to reset your Mac login password in the Apple Support article: If you forgot your Mac login password

Make sure that you're at the login window

The login window appears after you turn on, restart, or log out of your Mac. It's not the same as the window you might see when waking your Mac from sleep or stopping the screen saver, though it uses the same password.

Enter a password up to three times

After making sure that you're at the login window, enter any password up to three times until you see one of the password-reset options below.

Choose a password-reset option

After you enter a password up to three times, your Mac should show one of these password-reset options.

Option 1: Restart and show password options

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.

2. Select a user that you want to reset the password for, then click Next.

3. Enter your new password information, then click Next. 

4. When the password reset is completed, click Restart.

Let us know if this helps you.

Best regards!
