      Something to note here - with AI, if you’re using any sort of heuristic for your password, it’s pretty simple to work out a pretty good set of possibilities which makes brute force even easier and puts you at risk across the board.

      Always come up with random passwords that are as random as possible. If there’s a path you took to get to a password, in theory it can be worked backward.

      For example I know some people who only change a single letter when changing their passwords which is ultimately trivial to guess if the old password was compromised (hence the need to change the password or the need to proactively work against this possibility)

        I wish more websites allowed random words as passwords instead of forcing numbers and special characters (but not THAT special character, you have to use one of the ones on this list).

        People change their passwords by one letter or digit because they’re tied to these restrictive formats. If 5-6 random words was the norm, people would update more than just one character when needing to change passwords.

        “poison navy series ruler handshake papaya” is a fantastic password.

        “Ilovemygrandkids!123” is a horrible password.

          Just use a password manager and a unique, long, random generated password for every site. There’s no need or reason to know the password to anything other than your password manager and your primary email.

                The thing is the average person either can’t or can’t be bothered to remember even a dozen actually secure passwords, so they fall back to a couple of simple derivations of a common password, meaning each and every site a user signs up on represents an additional single point of failure.

          Agreed! I also think that the next steps would be getting rid of the need for users to even know their own password and instead replace with other securities like biometrics (with sufficient permutations possible to match or exceed passwords) and a physical device or something else entirely that removes the need to let the user in on what the exact password is

          Tools like Bitwarden will let you fairly customize the randomly generated password it makes. You can tailor it to not use certain characters for those sites that don’t allow it. And each vault object can be customized like that independently so you don’t compromise all your passwords by not allowing _ or (, you can also have it do pass phrases like you gave an example of

        I use a heuristic to update my main passwords. It’s not a character but easily guessable if you see it in plaintext and now you’ve made me facepalm my actions.

        I only use that for certain things because I use Google Oauth or Bitwarden for most things and you’ve just woken me up about what could be exposed.

          The goal should usually be as random as possible, if it’s got a series of steps to create, they can be traced backward

          Now the trick I’m not telling you is that randomness is hard to get because you need a sufficient amount of entropy (basically just means randomness, chaos, formally it’s how much uncertainty there is in the system) to ensure that it’s strong enough which can be challenging sometimes. For example, if your password is only 3 characters long and has 10 possibilities for each spot in the string, you’re only looking at 10^3 possibilities to guess accurately which is nothing to pcs and people with time on their hands haha

          I also take advantage of Bitwarden’s ‘passphrase’ generation as I understand that pass phrases can be even more secure.

          If the password requirements allow longer passwords I typicallyuse a passphrase generated by bitwarden, shorter ones I use generated passwords.

            The only thing that affects how long it takes to brute force a password is length and entropy (the different types of characters used). Passphrase is designed to make it easier for a human to remember, so if you are using a PM to remember it anyway, a 64 character random password is going to be better than a 64 character passphrase.

            I usually use the password generator in the 32 character range with all of the symbols, numbers, and characters included, since it seems like a lot of places don’t like longer passwords.

              wow thanks, I always remembering hearing people talk about passphrases being better, and saw bitwarden add a feature to generate them, I just went with it.

              But given I have no interest in remembering these pass phrases, it would make sense to use generated passwords vs passphrases as you said. Good thing my effort to transition to pass phrases was recent and wasn’t done too much yet.

                The rise of a pass phrase is more to do with mitigating the human risk in security which is people using memorable passwords. So a passphrase is typically easier to remember. That’s the theory anyway.

        something I did before letting bitwarden take over my passwords, was using a phrase consisting of 2-3 words + a series of numbers and special characters. Safer than anyone I knew at the time’s passwords. Admittedly it was not the most secure, as i only changed the beginning part of the 2-3 word phrase, and left the last word, numbers and symbols the same. So if one of those passwords were breached, it wouldn’t be too difficult for AI to brute force the missing pieces. So yeah I don’t do that anymore.

        That’s why correcthorsebatterystaple is the best way to do passwords imo, just 4 random words with a random special character dividing them and a random number tacked onto the end. Good luck brute forcing that or using AI to guess 4 randomly generated words in the correct order.

          we were talking about password changes, not creation though

          Guessing someone’s password with no prior history vs with an “averaged” prior history of the world/some large dataset are two different sized sets.

          If you’ve got a feel for how the majority of people are changing their passwords, guessing those passwords is significantly easier when compared to traditional brute force

          Edit:

          Passphrases are fairly good too but I want to see some real word examples of AI trained on some password dumps to see how much better it performs in comparison to traditional brute force and through targeted info gathering. I’m curious to see if there’s any user friendly techniques that’d work against AI specifically and it’s ability to find patterns most people wouldn’t pick up on

      As first spotted by VX-Underground, the scraped 2.6 million user dataset was released yesterday on a new version of the Breached hacking forum for 8 site credits, worth only $2.13.

      “Today I have uploaded the Duolingo Scrape for you to download, thanks for reading and enjoy!,” reads a post on the hacking forum.

    “Scraped” data suggests that it’s data available on public profile pages. However, the article also says the dump is a mix of public and non-public info. So which is it, scraped or not? It’s an important distinction, because data collection by scraping is technically not a breach.

      Take this with a pinch of salt but what I’m gathering is that it’s essentially just taking people’s public profiles but the Duolingo api also exposes users’ e-mail addresses (and possibly other info) that isn’t normally displayed as part of the user’s public profile via their app.

      In essence, they’re exposing more data than they probably should be and users were not really aware that data was being made public - that’s why people are upset about it.

            Finding the right email provider is what took me the longest, really. Went over all the options multiple times, constantly finding new alternatives and adding them to my list.

            There’s nothing right, and there’s nothing wrong when it comes to this. You’re gonna have to try out a few, and see what feels right for you.

            You should take into account what’s the most important for you;

            • Lots of space?
            • Lots of aliases?
            • Custom domain support?
            • Clean user interface?

            You’re probably gonna have to come to the realization that you will need to pay for it. You know, the old saying “If you’re not paying, you are the product”…

            If privacy is your number one concern, you should check out these three options:

            • Protonmail
            • Tutanota
            • Skiff

            Those are the ones that ended on my final list, and from those I chose Proton, mainly because I’ve used them for a long time already, and they have really good apps.

            Tutanota is the more simple alternative, which is also the cheapest option. They recently changed their premium packages, but you can still buy the old ones using a small trick.

            Skiff actually came after I already decided on Proton, and I’m not sure I’d have gone with Proton if I saw Skiff a bit earlier. Really looking like a great alternative, and they are offering enough in the free tier to be completely viable, even without a subscription.

            To prevent spam, and protect your email, you need an aliasing service, and fortunately this is more simple, since there’s only 2 on the market;

            I went for AnonAddy, because of the price and it being independent. You can get SimpleLogin included with the expensive Proton subscription, but I’m not really prepared to spend 10 bucks a month for email.

            My setup is to use a unique alias for every single website. These aliases are generated through addy.io, using my custom domain. That way I can easily toggle off an address, if spam starts coming in, but I can also change provider to for example SimpleLogin, if anything happens with addy.io.

            That’s just my setup, which I understand can seem a bit complicated to some, but it gives me the freedom, security, and peace of mind that I’m looking for.

          I’m in the process of doing that. It’s not a quick and easy process. I was so lazy with password, that I would just use a variation of 3 different passwords for everything because that’s all I could remember. Then I had a password exposed, so I decided to change all my passwords to unique passwords and use a password manager. I was shocked to see that I had 126 passwords saved in my browser. That took a long time to go through and change the email and passwords to everything.

            I totally understand you. It’s indeed quite an enormous task.

            I’ve been on the internet for 20 years, and just like you I used to use the same username, email, and password for everything. Slight variations for some stuff, but generally the same.

            A couple of years ago, I took the problem by the root, and went into my browser’s saved passwords, which I’ve migrates over a couple of times from Chrome and Firefox.

            I was shocked to find over 1200 unique entries, scattered over so many sites. Many of them I did not even recognize.

            I took it from the top and went down the list. Every site I would open, sign in to, and then change the password. If the site did not exist any longer, I would just remove it. If the site looked spammy, I would delete my account. If I couldn’t find a way to delete my account, I would change the email.

            Took me around 3 days to get through the list. There were quite a few duplicates, but also many that just didn’t exist. Ended up with around 500 entries, which I then exported and out into my new password manager Bitwarden.

            It feels good getting it done, but I also understand it’s a daunting task. To me it was fun to relieve some of the memories from my childhood.
