• phone: 6 digit pin
  • bank A: 4 digit pin
  • bank B: 5 digit pin
  • bank C: max. 6 character long alphanumeric pin
  • bank D: 6-12 character long alphanumeric pin
  • bank E: 4 digit pin, do not use the same number twice

This is so annoying. Also, I should probably get rid of 4 bank accounts.
