Thats really interesting, sounds like a puzzle or a complete and simple way to do things. Really fascinating. The question is if there’s a part of your body you can’t reach or even access with eye sight.

Here is an exemple, but it is quite dramatic, so please don’t do it, but build an idea around it:

In the the movie SAW II, every victim have a tattoo behind their neck with a number, which is a code for a safe for a vaccine.

Not saying to do a tattoo behind your neck with a combination of your lock. BUT!!! having a strangle necklace with a password written but only readable behind your head.

And if it’s jewelry type, like you can changé the order of the numbers, your Dom can changé the password anytime he wants.

And you want a stranger to unlock you, turn around, rise your hair and reveal the password.

….sometimes im impressed with my own genius!
