Hi and Welcome to the Community!
Please refer to this KB:
From your description, it is this user-controlled device lock password that you are asking about. But, your post confuses me a bit...for it's the exact same password you must enter when you connect to your PC. Is that not working perhaps? Or do you truly not know your device lock password?
Good luck and let us know!
