But I admit the same as really passwords are hard to remember and we are
often told not to record them anywhere, which means they need to be
something memorable in the life of the person concerned, so if somebody knew
me intimately they could probably get it in three or four tries.

Most "security" is really theatre. However pointing it out immediately
makes you a suspect, so it's best to keep mum ....

As Richard Feynman pointed out in one of his books. During the war he
got a bit of a rep as a safebreaker largely because he could often
figure out what the safe's owner (often a bigwig general) or scientist
would set it to.

The generals usually left them at factory default, the scientists very
often to e or pi.
