I let my password manager create 32 char passwords, that should be enough for a while. But of course then you have websites that throw you a 'your password is too long' message and have you find out by trial and error that they only accept 12 characters.

Or the off-by-one errors where they insist that 24 chars are the max, but in reality they accept 23. Probably never tested the limit.

Or websites that truncate your password after X characters when registering, but not when logging in, so you end up with an incorrect password and good luck finding out which limit the registration page actually uses.
