Fuck passwords
There is a (mildly) compelling reason for every bank to have a stupid password rule which is mutually incompatible with every site in existence: it means that compromising that other site's identity:password dictionary and then running it against your bank results in zero successes.  Regular users reuse passwords given the opportunity to do so, and most of them will happily cough up their bank password to, quite literally, any site on the Internet.There's got to be some weird game-theory solution for "Maximize for security while simultaneously minimizing the sum of all accounts on the Internet which have a password that could possibly collide with a valid password on this site."
