This is Firmware Lock, or EFI Lock. You cannot do anything until you get this password that it is prompting you for.
Here is what Apple says "If you can't remember your firmware password, schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider. Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase."
