@bram @glitch25 LOVE this. Reminded me of a diff knowledge security:

I used to work with a programming console had a one motion enable/disable screens & buttons shortcut that was the same on every install of that device.

There were optional username/password features, but the shortcut was generally accepted as secure enough because anyone who’d activate it would have at least a basic knowledge of what they were getting into.

Security: terrible in theory, effective enough in practice.
