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 ;-)

Example 3

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.
