Re: Passwords need to be rethought
Thumbs up to the initial letters method.
I favour lines, couplets, or even stanzas from poems or Shakespeare plays. You can include punctuation, it's far more memorable than horses, batteries and staples, and it's moderately incomprehensible to anyone who doesn't know the source quotation. If numerics are required, it's easy to add a bit of 1337 substitution.
For example: Nadwh,nafn,4hcttrwh - long and obscure, yet absurdly easy to remember when you know the secret. You can probably guess it, but it may take a while.
