Default [Q] Is there anyway to remove the PIN?

Dammit, old age sucks!

Got my N7 2013 all set up with the newest OTA update yesterday, re-rooted and unlocked....all my apps reinstalled, the WHOLE NINE DAMN YARDS. I use facelock with liveness check and a pin and have always used the same pin and THIS time, I did not put it in like I always have and now it is complaining that my pin is WRONG!

Is there anyway to remove or change that pin with out a factory reset?

I am able to get in it with face\blinking, but the lighting ain't always ideal.

Any ideas and\or suggestions are much appreciated.

If a mod wants to delete these, that would be fine.

And, it worked like a charm.
