I created a new TypePad account today to test our service that migrates TypePad data to WordPress—check out tp2wp.com if you haven’t yet.

Anyway, I was amused to find that TypePad wouldn’t accept the password I chose for my new account, but not for the typical reasons, like the password being too short or not containing a number.  Instead, it was because the password was too long!  TypePad seems to have a 12 character limit on passwords.

The XKCD cartoon above explains why imposing a maximum password length is doing your users a disservice.
