Paypal.

Paypal's password policies are shitty.

• NO spaces.
• NOspecial characters (they refuse to define special characters, though.)
• must be between 6 and 20 characters.
• refuses to allow ANY dictionary words (so diceware passphrases wont work.)
• They do not tell you their password policy until you get it wrong.
• They deny you the ability to paste passwords from a password manager.
