The most funny one was a professional and rather costly password checking tool.

Besides the usual other rules, it had a rule that the new pw must not be similar to the old one. For similarity, this thing checked each character in it’s place.

So you could have the old one:
“MyAssMy$1” and the new one:
“$1MyAssMy” and it was not similar at all :)

Not so much password requirements as just a completely removed implementation:

To access payment stubs in a data center (not us) that I worked at, the user account was our public email address and the password was a personal code, sorta like SSN, but that code could be easily looked up as it was public info.

I showed the director of HR, who authorized this her own payment stub as evidence that this was baaaaadddd

So she asked me to check that system for more issues

Turns out it stored passwords in blank (wtf) and would authenticate with two queries. First query would check if the username (email) exists. Second query would check if the password exists. If both exists, you’re in! So i could login to any account with MY password…

This is a tip of a very big iceberg there

Most absurd was from a job I had in college. This was the password to log into an ancient dumb terminal (literally a monochrome black and green display) on a local-only network that only handled our time clock.

Requirements:

• 8 characters exactly
• You supply the first 4, the system generated the last 4
• I can’t remember if it allowed numbers, but there were definitely no special characters and I think it was also case-insensitive

Required to change password every 30 days.

I had a wi-fi device a few years ago that would require a password up to 12 characters, but that requirement wasn’t explicitly written anywhere. The device would gladly accept a 13-character password, for example, but you would never be able to log in again (factory-resetting was the only way to undo).

More recently I purchased a Lennox HVAC system that came with their proprietary thermostat (an Android tablet with a wall mount). During the Christmas break I got myself a new wi-fi router and had to reconfigure all my wireless devices. After 2 days, the Lennox thermostat was the last device to join the new wi-fi network… and it failed because their password could have any character EXCEPT the asterisk — and my new password had an asterisk. I didn’t like the idea of redoing all my other devices AGAIN just because of this idiotic password rule, so I ended up creating a new SSID just for the thermostat. I named it LENNOXSUCKS.

Not sure if it falls under the same category, but the way Activision handles (handled? I haven’t used them since) passwords was atrocious! I had to reset my password to get back into my account, I used a random diceware password, it accepted it. However! The client on both Windows and Xbox wouldn’t let you input a password longer than I believe 20 characters. So while you can set a 25 character password, you can go fuck yourself if you actually wanna log in…

A company I used to work for is big enough that everyone reading this has heard of it. They had this wonderful security nightmare going on:

When you were hired, the company would issue your user credential with a standard password that was “CompanyName1” and require you to immediately change it at first logon. Everyone knew this password because everyone got it when they were hired.

Password policy required everyone to reset their password every 60 days. Not the worst ever but still pretty aggressive. And with the rise of all the mobile devices connecting with your corp account it was getting to be a worse and worse experience.

Can you guess yet how these two policies are linked in my story?

Well, some of the C-Suite executives didn’t have time for any of these security shenanigans. So they would have their executive support person log into an administrative console and reset the exec’s password every 59 days to the same value that it currently had, thereby bypassing the password re-use filter.

That value they were continuously setting was… “CompanyName1”

I know of at least two executives that were doing this while I worked there.

The oddest I’ve ever encountered: EXACTLY 15 characters long. No more, no fewer. 15.

Honorable mention: Various online accounts where I used my password manager to generate a long, secure password, which the website accepted without warning or error. I was then locked out because their user management system could not handle such long passwords (had to create a second account with a much shorter password to find that out) 🤣

The worst I’ve ever seen was a site that required passwords to be 4 digits.

Max length of something under 18 …

Irks my gears

My work was using some MS-based account system, but I don’t know if this was stock or something they modified. When you had to change your password, it would tell you if your new password didn’t meet the password requirements, as usual. What it wouldn’t tell you was what those requirements were…

So yeah, the requirements the system won’t tell you about would have to be the worst one i came across…

My community colleges:

Passwords must be 12 characters long, contain at least one uppercase letter, one lowercase letter, a number, and a special character; it must also be changed every 30 days. There was also some sort of alogarithm that checked if your new password is too similar to any previous password you had used, and rejected it if it was too close.

Hilariously, if you had a link to the page the password was supposed to limit access to, you could bypass the password page entirely. As such, I never changed my password.

My old bank required you to have a password 12 characters long exactly, and to login you have to give the characters in specific places.

I would ask you what are the 4th, 7th, and 11th letters of your password.

Anyone want to guess why that aren’t my bank anymore?

One special character.

Seems logic right? Until you get that it is one and one only. Took me some time.

My favorite is a major credit card company with case-insensitive passwords. They also only allow a small handful of special characters, so the total possible character space is roughly 42 characters. Needless to say, I chose to use a password that was the maximum allowed length (which was sadly also only 32 characters).
