Yup, the field will need to be bigger. Not only is a passphrase easier to remember, it's more difficult to crack.

>Ok, so the password, known as pass phrase, is then much longer and this seems to fit better in certain places where users are more into remembering a pass phrase then a password. Is this pretty much how it is? I would then assume the encrypted field in the table would then be much longer as a phrase is usually much more than a password.
