Paypal did this with 20 characters. I can't even remember how I figured it out so I could login.

I don't know if it truncated it automatically or it just stopped accepting input after 20 characters and I of course did not notice since the password entry fields were masked.

Their password reset form didn’t have the restriction, so you could reset your password to 21 chars, and then never log in again
