A is a realistic case of security by obscurity - there's a sizable amount of people who believe that to be secure.
B is in my opinion much less realistic: very few people believe a password two bytes long (or better, with two bytes of entropy) to be secure. Even a trivial password like "TelnetSucks" scores 31 bits of entropy with https://apps.cygnius.net/passtest/.
