UUIDs are good passwords.

V4 - yes. V1 and v2 - nope

A password that you can remember is way better. An UUID or half UUID does not even make a difference security wise. That thing is more unique than every grain of sand on earth. Why would you want that.

Password only stored in brain is the safest. Include a swastika, i'm sure it won't get hacked by brute force.

But no, UUID's are terrible passwords, especially because it requires you to store them, and storing passwords is incredible bad idea.

And if you don't give enough fucks about the password, why the fuck would it be an UUID?

The logic these days is like AAAAAAAAARGH

Remembering passwords is stupid, has less entropy, bet you reuse it across a bunch of sites, and is still vulnerable to phishing

On top I want to add, an UUID has no special chars enough or is too long for a password field. So much flaws.

@devRancid some people have the capacity.

Not remembering, but on occasion you must be able to copy certain passwords by hand. Especially if you follow your earlier advice and store them in a paper notebook.

@tamagotchi If a UUID is too long for the password field there's something piscatorial in the works.

I just want to note that passwords are actually meant to be text that you can remember.

If it’s something generated with random symbols then it‘s more of an auth key.

@Lensflare I feel like this is where passphrases came around. From security perspective they're the same as passwords, but from user perspective they might be better.

I like a good passphrase.

The best ones are grotesquely obscene. Makes them more memorable and also gives you a powerful incentive not to accidentally type them into that teams chat on the other screen.

Whoops…

@tamagotchi

Upvote as in it's better to have something you remember, yes.

Besides that, UUIDs are indeed more entropy than atoms in the solar system. So they make good passwords that don't need hashing nor salting. (Bear in mind you still wanna do this if only to maintain secrecy).
