Original Title: Lock on screen MacBook Air 2017
Sounds like it's asking for a firmware passcode. If that's the case, you can' "bypass" it. If you don't remember the firmware passcode, you'll have to take the machine and the original proof of purchase to Apple to get it unlocked.
Where and when did you buy the machine?
