Sounds like you've misunderstood the purpose of this.
I usually just use a single password across most services, so they all know your password, even if you trust them not to store it in plain text. It's infinitely more secure to use something like PW, never entering your main/master password into any other services and then have a generated hash that really means nothing to anyone (can't be decoded or anything stupid). The length factor here makes very little difference, and only you need to know that you use 40 character password (yes, 40, which I bet is longer and more secure than your current password(s))
