My brain went here too. I'm guessing that one box missed the truck (either it was damaged during loading or had a manufacturing defect), so a full shipment is 3 x 3 x 23 x 2000. So my SWAG:
I'm not a security expert, but I have an opinion on passkeys: I think we should stick to using them only for 2FA. At least for any site where the security really matters.
In my mind, a passkey authenticates the device, while the password authenticates you, the user. Passkeys let us limit which devices are allowed to connect with our credentials. A hacker in Eastern Europe could steal my login, but if their laptop isn't authorized, it makes an account takeover much harder.
(Side note: This is also why I'm uncomfortable putting TOTP codes and passkeys in the same password manager as the regular login credentials. It effectively defeats the whole purpose, turning multi-factor authentication back into single-factor again.)
1 box = 3 x 3 x 23 bars
1 pallet = 10 x 10 boxes
1 truck = 20 pallets
