Two-factor authentication

I think that’s a 3 factor authentication 😁

Hm, if we're not talking about the shelf, but its contents 🤔

hmm i wonder how a robot can possibly figure this out autonomously

It would use brute force

Still only single factor because all three are something you have and solution doesn't rely on anything from another category (e.g. something you know (password, PIN), something you are (biometrics), somewhere you are (geofencing)).

Indeed

😅 I feel it
