How to recover a forgotten passcode on MacBook Air
I’m locked out of my Mac airbook and it’s not recognizing my passcode. I might be entering it wrong but I don’t remember it now as it’s been a while since I last logged in

The login password does not exist in a readable form anywhere on a Mac, so there is nothing to recover. It can only be reset.
If you forgot your Mac login password - Apple Support describes what to do, including options If you can't reset your Mac login password.
Follow all those steps all the way through to the end.
