Ameli.fr (French national health insurance)

This was very painful to find a password that works with this one and that I can actually remember (I ended-up using my bank-account number because everything else failed). It took me maybe one hour and I thought I would become crazy (and yes, the session expires frequently while you are actually thinking about a password).

The password must be more than 8 characters
But you cannot use more than 13 characters
You can only use digits
You cannot use your birthdate or your login
You cannot use a sequence of digits (if your password happens to contain 56 or 89 it will be rejected)
You cannot repeat the same character (if your password contains 22 or 55 it will be rejected)

8 to 16 characters, at least one number and one letter and last but not least NO special characters, and can't have a password that looks like your username too. Oh, and passwords are NOT case sensitive.

A real time travel adventure through the password rules of 2005!

Exactly eight characters.

Please nominate a password which contains UPPERCASE, lowercase, numbers and symbols. Password should not be the same as the user ID. Avoid using consecutive characters such (ex. abc, DEF, 678) and invalid characters such as [!#$%^&';"].

Best Buy

You can enter whatever password you like! But you probably don't want to make it too long, because you'll break us and you'll never be able to login again.

They force you to enter a password that has 8, 9, or 10 characters, then they lecture you on how to create a strong password.

Although the prompt suggests good things, after many failed attempts to set a new password, it turns out you can ONLY use the special characters shown in the prompt

"To ensure the highest level of security, your password must have... 8 digits". And it must be entered using a funny keypad with the digits in the wrong order.

California Department of Motor Vehicles

They also prohibit pasting into the password field by using a JavaScript alert() whenever you right-click or press the Ctrl button, so you can't use a password manager.

CenturyLink

So many bad ideas: a low maximum length, requiring six specific character types while not accepting common symbols, plus a weird restriction that makes random generation harder.

Charles Sturt University

Prevents spaces and a set list of characters, limits to 30 characters and can only change your password twice per day.

Chase Bank

Max length restriction (32 characters).

Chegg

Here are the (only fairly poor) rules for a new password. Enter 64 character password that matches all the rules (notice no rules on maximum length). That password you entered looks good! But we didn't change it. And your old password doesn't work. Or the new one. ¯\_(ツ)_/¯

Comcast

Deloitte GlobalAdvantage

Rules that are completely arbitrary that basically make all safe passwords wrong, instead forcing pseudo-safe password combinations.

Delta

It's a good thing they don't store personal information such as your passport number... oh wait.

DJI

The symbol \ is banned without a notice, it'll probably escape whatever you'll put in, just why...

Fidelity National Information Services

By the time I'd finished reading the rules I've forgotten all of them.

You can't use &<>'"\|´`, spaces and any other non-ascii character.

ING a dutch bank in almost 50 countries

Max 20 characters, must have one number, one upper case character and one lower case character. You can only use certain special characters.

ING Australia

4 numeric digits. "Added security" by randomising the positions on the keypad. Must be clicked.

ING Romania's Internet Banking Portal

No more, no less than 5 digits. This is the password you use to log in and to confirm online transactions. They used to have "normal" passwords and they forced everybody to change to the 5 digits versions. They said they've made it "so it's easier for you" and it's OK, because everybody has 2FA.

Inria

This is the account for those who work at Inria <https://www.inria.fr/> "the French national research institute for the digital sciences".

Intel

Izly by Crous

Izly by Crous is an imposed French payment service for the university. You can't pay your daily meal without that because yeah you know cash is an ancient dumb thing.

Your username is [email protected] or your phone number. We only allow you a fixed 6 numbers password. Oh yeah we also block your account after three failed atempts. How convenient when the only thing you need to know is the name of someone and where they study. How convenient indeed.

Oh and also look we got pages NOT TRANSLATED IN FRENCH because duh.

Jitterbit

While not the dumbest password rule, still dumb.

Microsoft (work accounts)

What doesn't seem to be a problem for personal accounts, is for work accounts from Microsoft (e.g. Office 365 etc.).

Maximum 16 characters. So forget about using your new fancy diceware password here - or really any secure passwords in general.

Oh - and besides that, please don't use any "exotic" symbols, like ¤ or €. Or the letters Æ, Ø or Å from the Danish alphabet. They all are supposedly "spaces".

Mindware

You "may use special characters", but only some of them - and we won't necessarily tell you which ones.

MKB NetBankár

It only accepts lowercase letters, uppercase letters and numbers (any other character counts as forbidden character).

Also, if your password contains any invalid character, it will get marked as "Identical to the former 10 passwords".

To make it more fun, during the registration, it allows to set a 24 characters password to login to their website.

Once you try to login with the password, it will say that the maximum length accepted is 16 characters.

What actually happens, is that they let you insert 24 characters during registration, but only the first 16 will get actually used as password.

Mobi Bike Share

Your PIN (which is the password you use to login, which lets you, say, buy hundreds of dollars worth of bike-share subscriptions off the saved credit card) must be four numeric digits. Helpfully, they even give you an example of a PIN: 1234.

Movistar

Passwords must be greater than 6 characters, and have an arbitrary set of rules we don't tell you about until after you try to set your password.

SAP Cloud Appliance Library

Passwords between 8 and 9 characters are the best.

Scandinavian Airlines

The password rules itself is fine, but, it doesn't inform about the max length of the password. Their max length is 14 characters, so even if you enter a password of 42 chars, you can login with the first 14 of it. In this case, I changed my password to Super_l0ng_password_that_fits_all_criteria, and could login with Super_l0ng_pas

Answer form SAS customer service:

> Hi,
> Thank you for your e-mail.
> Our website only takes 14 characters as a password, so somehow when you registered > it took all 49.
> But since our website only asks for 14 characters anything after will be valid.
> I would advice you to change your password.
> Have a wonderful day.

Sparda-Bank

Sparda is a group of German banks. They all use the same login form (except for Sparda-Bank Berlin, see below). Their equivalent of a password is called Online-PIN. As the name implies, only digits are allowed. (Zifferneingabe means "digit input"; it opens an on-screen number pad widget.)

Not mentioned explicitly: Your PIN is limited to 6 characters, i.e. the range of valid "passwords" is from 000000 to 999999.

The odd one out is Sparda-Bank Berlin, which has different rules:

At least 8 characters.
At most 20 characters.
Only the following characters are allowed: a-z, A-Z, ä/Ä, ö/Ö, ü/Ü, ß, 0-9, and the "special characters" @!%&/=?*+;:,._-.
Your password must use either digits only (like a PIN) or at least one digit and at least one uppercase letter.

Sparkasse

„Sparkasse“ is a group of banks which is pretty popular in Germany. It calls its passwords „PIN“ („persönliche Identifikations-Nummer“ — personal identification number), the rules are pretty horrific and its not even a number, even though it is called as such! Here is a screenshot from the branch where I am from (Jena, Germany), but since they have a central IT, I think it will be identical in other branches:

The rules are as such:

Only 5 characters
Small letters (a-z)
Large letters (A-Z)
Numbers (0-9)
„Special“ characters: ä,ö,ü,Ä,Ö,Ü and ß (Not suprising for a german Company)

After the rules there some hints on how the password should not look like:

Combinations of your initials and the birthyear
Your phone number or parts thereof
Your zipcode
Commom combinations like 123ab or 55555
Full or parts of your login credentials

Sprint

Sprint "upgraded" their security and disallow special characters.

Telekom/T-Systems MyWorkplace

Telekom's MyWorkplace is a Single Sign On / login hub for their Open Telekom Cloud which is basically an Amazon AWS clone. It's rather new and especially for business customers.

Vio Bank

The password requirement is not even fully enumerated. Upon inspection of the source code, the following lines were found, hidden by javascript: "Must include at least %MINSPECIAL of the following characters:-.~!@#&_{}|:$%^*()=[];?/+"

The actual list of special characters that are prohibited is correctly enumerated there. It's a result of a misapplication of the variable allowedSpecialCharacters found here.

It took under 5 minutes to find the bug after looking at the source for the first time. This is a bank.
