At least Sparkasse and HypoVereinsbank and IIRC also Postbank allow
changing at the ATM terminal.
And a birthday isn't as idiotic as 1234 or 1111, as long you assume a
standard pickpocket doesn't know you personal data (OK, your ID-card
within the same wallet... maybe no good idea. Then not your own
birthday but from a person or your cat you can remember, or better
your wedding day, which normally would be forgotten always ;-)

MY use case would be: I have, let's say two bank accounts at
Sparkasse, one at Postbank, one at HypoVereinsbank (possible reason:
two bussines accounts and one private account and one from a
inherited account) and I can remember ONE good "random-like"
4-digit-PIN, but would mangle definitely four different PINs (been
there, done that...). Then I chose one and the same "good" PIN for
all four cards which I don't need to write down anywhere and
everything is OK.
