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.

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)_/¯

White label online banking provider. Typically appears as BANK.ibanking-services.com or BANK.ebanking-services.com. If your small local bank has a crappy online banking experience, these guys probably provide it.

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

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.

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.

Lloyds Bank

Max 15 characters, min 8. You cannot use ANY special characters - alpha-numerics only. This amazingly terrible password policy combines with a known phrase (The "Memorable Information") of which you will be asked for a random 3 characters of if you get your password right. This phrase has similar alpha-numeric restrictions applied.

While not the dumbest password rule, still dumb.

Kryterion Webassessor

I was quite suprised to see this when I was registering for my Google Professional Cloud Security Engineer certification. Nice part is that they don't allow quotes as special character, so I assume there possibly might be some other issues on their backends. :-)

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.

Minecraft

Using a 16 character password seems to work. Everything else above does not always work. Also, passwords that are too long are still changed, so you have to reset them by email.

Minnesota Unemployment Insurance

Locked to exactly 6 chars, alphanumeric only, not special chars.

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.

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.

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.

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

Especially because it is for business customers, there's absolutely no reason to limit a password to 16 characters. Even special characters are limited to a certain set.

Thames Water

Can only use the "special" characters on that very limited list, excluding symbols so exotic as an underscore, even. This is despite their own strength checker saying the password is strong.

Three

Password must be at least 7 characters long. The maximum length is inconsistent, however: when changing password, the maximum length is 30, but when resetting password via email link, the maximum length is 12.

Ticketmaster.de

Your password length is limited between 8 and 32 characters.

Trade Me

Won't allow spaces or single quotes. Maybe other characters as well - they do not say up front - but the password they accepted contained lots of other special characters.

TreasuryDirect

Will allow most passwords longer than 8 characters. Doesn't tell you there is a maximum length of 16 characters. Then forces you to type it with an on-screen keyboard with no capital letters.

TwinSpires

You can gamble on our site. We'll keep your money secure with a 12 character password!

Ubisoft

Only tells you the rules after submitting and clicking a link to a pop up window.

Unicaja

Username is your national Spanish ID (easy to find). Your password must be 6 characters long. You can't type, only select characters from the virtual keyboard

United Parcel Service of America

Your password must:

Be between 7 and 26 characters long
Contain at least 1 lowercase character
Contain at least 1 uppercase character
Contain at least 1 number character
Contain one special character (!@#$%*)
NOT contain first or last name

United States Postal Service

Pick from an arbitrary list of symbols, and no repeating characters.

University of California San Diego

Passwords must be between 8 and 11 characters long!

University of Texas at Austin

Because of the last two rules, which ban dictionary words and any variants using symbol substitutions, neither of the passwords presented in the xkcd comic are allowed.

University of Windsor

The password policy applies to alumni as well. Must be at least 10 characters long, with at least 1 upper case and 1 lower case character, at least 1 number, at least 1 special character. Password expires every 120 days, and you can't reuse an old one.

USAA Bank

Password cannot be longer than 12 characters but they don't tell you that until after you try a new password. To make up for this fact they've added dubious additional security features on top of this weak foundation.

URSSAF (French employers tax collection service)

When setting a new password: Password must be exactly 8 characters, at least 1 letter, at least 1 number, but no special characters.

Vancity Credit Union

Personal Access Code (or PAC–they are too ashamed to call it a password), must be between 5 to 8 digits and cannot start with '0'. (no letters or symbols)

Very.co.uk

Password field allows only the listed Special Characters ($ . , ! % ^ *). You're also forced to use both upper, and lower letters, as well as a number.

Vietnam Airlines

[[:alnum:]]{6,8}

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.

Virgin Media

Your password needs to be between 8 and 10 characters long, with no spaces, and must contain only numbers and letters. The first character must be a letter.

Feb 2020 Update: policy remains the same but the description is hidden leaving you to guess the acceptable length/chars. Users are now left with helpful hints after JS validation.

Virgin Mobile

You can only use PIN as your password.

Virgin Trains

Your password needs to be between 8 and 10 characters long. Previously this would silently truncate the password without warning, causing confusion when the password wouldn't work.

Walmart

Your password length is limited between 6 and 12 characters.

Wageworks

In addition to the following rules regarding passwords...

8-20 characters in length
Include at least 4 of the following: lowercase letter, uppercase letter, number AND symbol

After you request a password reset and you receive an email with instructions and link to reset your password, you are presented with this password reset form. Your password length is limited between 8 and 16 characters. Additionally the form breaks with an error if you use any special characters. The form does not mention anything about special characters. Waze is owned by Google.
