    Sure just if fully given in this way it’s basically the same as an 11 character password. And more damning is it’s not really random. I’d use this as a case of more education on longer passphrases aren’t always longer entropy on their own if they are non random phrases is all. And there’s a lot of different word lists out there. I’d give this a go on my system and see if a guided run with the knowledge of how things were built can brute force it.

    The big thing is a secure passphrase or password should be resistant to attacks even if there is perfect knowledge of how it was generated. In this case all lower case English words in a non random phrase works against that.

      Only of the attacker knows whether it’s a password or phrase. I’d argue that passwords are far more common and that’s what a cracker would focus on first.

      As far as I know there still is no way to create actual randomness. You’ll still have some pseudo-random number generator and a hopefully unguessable seed. If you have “perfect knowledge” about that, cracking the password is almost trivial.

        Morden computers have hardware that generates entropy. It is used for cryptography.

        Also, when creating password for yourself, you can use a simple physical dice, it’s truly random.
