Some millionaire in my office: "Hey, Sanctus, what's my password for my computer again?"
Me, who can barely afford to fix my car: fights the urge to use a letter opener as a weapon
That’s a really long password no wonder they forgot it.
Sick entropy, though.
Horse battery staple moment
Correct
Depends, if you treat the individual letters sure but if you look at the words as the atom of information most password crackers wouldn’t take long.
There are ~100 symbols on the US keyboard, many not permitted in a lot of online passwords (stupidly).
There are 11 words in the "passphrase". Fight, letter, open, urge, weapon are not in the 100 most common English words. Urge is not in the 1000 most common English words (let alone fights vs fight, or opener vs open).
I think it would be a fairly strong password. You can reduce the entropy a bit by predicting likely next words in a sequence, but that would be defeated by adding some non sequitur(s). "fights the urge to use a letter opener as a scooter" or something.
Capitalization, intentional typos, spaces or not, ending punctuation? There a for sure ways to improve it as a password while still keeping the easy to remember, easy to type aspect. Overall it's a great strategy to teach people for making passwords.
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.
