I didn't like it when LJ told us to lose our old passwords and replace them with meaningless, unmemorable combinations of letters and numbers. I fixed on a formula (it has a key) and wrote it down and promptly lost the piece of paper. Oh, well, I thought, I'm permanently logged in so I'll never actually need the damn thing anyway. But- of course- the time came and with it the judgement and I was asked for my password and didn't know it, but- did I panic? No, I went and fetched the book that holds the key and retraced the steps by which I'd devised the password in the first place and- bingo- worked it out at the first attempt.
I'm so pleased with myself. Fetch me a crown of tinsel and holly. I am the Conquistador of cryptograms. The Caesar of seasonal smugness.
