    And despite security recommendations, too many IT depts still force password resets every 90 days…

    And people confronted with this change their password from “p@55w0rd!1” to “p@55w0rd@2”. Yep extra-secure!

      I work in the IT section of a bank and they force a change every 30 days and can only have an 8 character password no more no less 🙃

      Some IT guys have caught on to this and require 2 digits difference.

      So “ThisJobSucks#11” becomes “ThisJobSucks#22”

          Well they don’t need to store it to a drive. You just entered your old password in order to login and authorise your password change.

          It’ll still be in memory against your session.

          Used to have monthly changes for a Microsoft account. When trying to change, it said “You used this password 6 months ago, please use another”, besides the “passwords needs to be at least this different” message. Clearly they are storing them, not sure if they’re stored cleartext or they’re decrypting them on the fly somehow

            You should not be able to decrypt a password, passwords aren’t encrypted but hashed, they would be insecure would they be encrypted.

            Hashing differs from encryption in that it is irreversible, because two or more strings might result in the same hash if the hashing function is applied to them (hashing is not injective).

            But since your password will always yield the same hash you can compare the two hashes and if they are equal you are considered authenticated. If you try to log in with a different password (or even the hash of the correct password) then it will produce a different hash resulting in a failed authentication attempt

            The way crackers get a password if they have the hash is by guessing pw candidates and using the hash function on them, if its the same as the hash they have they found the/a valid password. The guessing can be quite involved and with enough time and data about a victim often 12-13 digit passwords with special characters and all can be cracked - If the victim used a somewhat mnemonic pw that is. Generated pws from a password safe are much safer (but usually also longer).

            In your case I suspect MS was storing a history of hashes which is not advisable as it gives potential crackers more to work with, but its way less bad then storing plain text or encrypting passwords

      A job I quit about 6mos ago required monthly changes. It was awful. And, yes, it absolutely led to me just incrementing a number at the end. I knew it was time to quit when I was about to hit double digit numbers.

          It was a joke.

          But also, holding a shitty toxic job for 10mos took a mental health toll.

          But also, I don’t know, in some cases that might be good advice. Since 2020 I’ve changed jobs every 6-10mos and I’m making triple what I made in 2019, so that’s nice.

        I college we had to change our password every semester. Guess who added the semester number onto the end of their password. Hint: everyone.

        Same as a government job that required monthly password changes. Well, at least those people had more security than the post-it note on the monitor people

          Then you finally do the password change, go to login and now the new password doesn’t work because you copied it to clipboard and overwrote it somehow in that small time frame goddamn shit! I always win+r and put it there until I know everything is all good.

        If I recall, a few (most) security experts now support written-on-paper passwords. Why? Because it is the solution for users who would otherwise commit far a more egregious security faux pas otherwise.

        In most circumstances, it is easier to keep the notebook secure than your wallet, your car, etc. And let’s be honest, the list of suspects are REALLY short if someone breaks into your house, opens the third drawer, grabs the notebook and runs. And if it’s more than that and somebody ransacks your entire house, I guarantee having to change your passwords is the least of your headaches.

        Ultimately, physical compromise is the lowest possible security risk for most people throughout their lives. Yes, it happens. Yes, it sucks. But having your bank password out in the wild with nobody realizing it is possibly far more dangerous.

        That’s even more reason to use a password manager. You’re far more likely to have unique passwords per site. If one gets compromised, others don’t.

          Idk who is safe to use for password mgmt. I haven’t seen data leaks for my banking institutions who probably have enforced regulations for IT security. Are there standards in place for password manager products? What brands are reputable?

            Yourself. I use Vaultwarden on a Raspberry Pi. Lots of people use something like KeePass and sync it with Dropbox or something similar. As far as someone else hosting it, Bitwarden seems like the go to (and is the project that Vaultwarden is based on).

      I promise you that does not help.

      I suspect a large number of these incidents are due to the password field in the login page allowing fewer characters than the field in the sign up page, so the password gets truncated. A couple of help desk meat shields have confirmed that for me, but mostly I think this because it seems to fix itself if I use a shorter password.

      How short, you ask? Who tf knows! They sure as shit won’t tell you! Just spend the next 20 minutes trying shit til it works, because you have nothing better to do with your time!

        I won’t say where I work but we have strict password requirements including that they have to be exactly 8 characters long.

        Yeah our passwords aren’t very secure as we also have to change them every 90 days and if you miss the window by 3 days you have to call the IT desk to reset it which takes about 45 minutes to an hour. And in that time you basically can’t get anything done.

        At home I use a password manager and all my passwords are randomly generated and whenever possible 2fa is enabled.

          Not sure if you’re in the US. But if you are, you should leave this anonymously on the security team’s desks.

          > Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically). However, verifiers SHALL force a change if there is evidence of compromise of the authenticator. - NIST control SP 800-63B Section 5.1.1.2

          Basically a fairly widespread standard of security. All kinda of complaince you can fall out of if you do business with anyone who cares about NIST controls.

          Personally I would use a password manager for at work as well. Bitwarden can generate 8 character passwords. Easy enough to remember and if you forget it’s right there on your phone.

          Get as many people as you can to change their password on or around the same day. 93 days later either bombard IT with simultaneous requests or maybe stagger them to eat up their resources for days.

      The joke is that he set the password to the same thing he thought it was to begin with — the same password the site said was incorrect, it’s now saying was in fact his old password.

      I forget where, but this has happened to me before. I thiiiink the logic was that it compares to your last 3 passwords, not just the most recent one. So if I had the password “hunter2”, then changed it to “swordfish”, then later forgot that and tried to log in with “hunter2”, this is what would happen.

      I’ve also had similar but completely inexplicable experiences with my cell phone provider, who shall remain nameless. My best guess is that my special characters (still ASCII but not alphanumeric) broke their poor lil database. It wouldn’t accept anything until I set a strictly alphanumeric password.
