If you are the administrator and you forgot your password to you computer, there is a method to reset the access password. Check out this support article for instructions: https://support.apple.com/guide/mac-help/reset-your-mac-login-password-mh35902/mac
Just so you understand, that using the Apple ID to reset your computer password will reset and erase the entire keychain in iCloud, so you will lose any saved passwords and certificates, and will have to re-login to all your devices and start any Safari passwords from scratch.
