        Many PW managers let you generate passphrases, which are all around better than random strings. Length is the most important factor so

        finance-caffeine-utopia-redress-unseen

        Is way stronger and easier to remember (and type) than

          Huh, TIL. I had no idea that was an option but that’s super useful for things I need to type in on a device with no keyboard, or even things I can’t access my password manager for. Thanks for the protip there!

          Is it really safer? I mean when trying to bruteforce a password, one would have to make a guess whether it’s a passphrase or not. But if you decided to check for pass phrases, wouldn’t the one you posted be cracked in 5 times the amount of words in that dictionary? I’m not sure how large the vocabularies of the generators are, but I would guess a random 17 char password might be safer than a 5 phrases password?

            And you would be very wrong about that. A 5 phrase password has entropy. “finance-caffeine-utopia-redress-unseen” is 28 characters. If you add in a different symbol between the words and add a number somewhere, this password becomes incredibly difficult to brute force.

            I’ll let xkcd explain it better.

              Youre right,different separators, numbers and even capital letters change my theory alot

          And pass phrases are faster to type and with less typos even though they need more characters than passwords to be the same secure.

          For symmetric keys, since they cannot be weakened using quantum computing, their strength can be assessed by their bit-equivalent amount of entropy:

          • 40 bit or less - easily breakable
          • 64 bit - not so easy, but doable
          • 128 bit or more - basically unbreakable

          Those are equivalent to, respectively:

          • 0-9 - 12, 19, 38 characters
          • a-z - 9, 14, 28 characters
          • a-z0-9 - 8, 12, 25 characters
          • A-Za-z0-9 - 7, 11, 22 characters
          • A-Za-z0-9+special - 7, 10, 21 characters

          Moral of the story: drop the special characters, and even the numbers… and even the uppercase. A 30+ character long all-lowercase pass phrase, is already unbreakable.

          Check @falsemirror@beehaw.org:

          finance-caffeine-utopia-redress -unseen

          …is already over 128 bits.

      Obviously any reputable password manager is better than none at all, but I strongly recommend using KeepassXC on the desktop and a suitable mobile client for phones and tablets, and syncing the database across devices with an encrypted peer to peer sync tool like Synching.

      I’ve always been nervous about being part of a large, juicy cloud hosted target, and LastPass was the proof that those concerns are well-founded.

        KeepassDX for mobile is on F-Droid and can use the same file as accessed from KeepassXC from Laptop, synced by Syncthing.

          I can also recommend Keepass2Android, which I’ve been using for years.

        Yep. If you’ve got the technical knowledge and a server, self hosting Bitwarden is quite easy. And your vault is end to end encrypted.
