Sites

Table of contents

Restrict the inclusion of a % character.

Admiral

Forced to change the password during the first login. At least they could use proper grammar in their rule list.

ADP

  • Requires at least 6 to a maximum of 12 characters [sic!]
  • Allows only digits and letters without umlauts
  • Allows only specific special characters: ? ! $ €% & * _ = - +. ,:; / () {} [] ~ @ #
  • Allows no spaces

Advanzia

  • Between 8 to 12 characters
  • Should contain capital, lowercase letters and numbers

Air France

Sometimes I forget that caps-lock is on, glad it doesn't matter.

American Express

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)

ameli.fr

Their site says "All information is kept safe and secure." Just not as secure as you'd like.

User Password must be between 6 and 14 characters and contain 1 numerical value.

AmeriHealth

Your password needs to be between 6 and 12 characters long, must contain only letters and numbers.

AmiAmi

Your password needs to be between 8 and 16 characters long - no special characters allowed.

ANZBank

Between 8 and 16, so I can't go up to 20. Oh, and thanks for restricting one of the most common special characters!

AOL

Can't contain 3 or more consecutive identical characters.

Apple

Service for managing employment documents of the German company Datev.

Only the following character categories are allowed: Letters, numbers and this special charaters set: !#$%&()*+,-./:;<=>?@[]^_`{|}~äöüßÄÖÜ

Arbeitnehmeronline

Your password contains characters not listed. Therefore, they do not match.

Arlo

The only special characters allowed are underscores and hyphens.

ATT

8 to 15 chars. No special chars allowed but requires special chars. Also requires lowercase, uppercase, and numbers. Consecutive chars are prohibited. Did I mention the page hangs while you type? That eye icon tho.

Banco Mercantil

Passwords limited to 8 digits.

Bank Millennium

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!

Battle.net

Username is your national ID (easy to find) and your password must have up to 6 alphanumeric characters only.

For a bank account with all your money in one of the largest financial institutions in the world.

BBVA

Exactly eight characters.

Bendigo Bank

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 [!#$%^&';"].

BDO

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.

Best Buy
Best Buy2

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.

Blackrock

16 maximum and no special characters. Protecting your US healthcare information.

Blue Cross Blue Shield Massachusetts

Password must be exactly 6 characters long and no special character.

BMO Bank of Montreal

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

BMW ConnectedDrive

"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.

Boursorama

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.

California DMV

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.

CenturyLink

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)_/¯

Chegg1 Chegg2 Chegg3

Letters and numbers only, no symbols. Also an undocumented maximum of 12 characters!

CIBC

Your password should be difficult to guess as long as it's not over 16 characters long.

Another financial institution certainly storing passwords in plaintext.

I wonder if they cooperate with NSA to enforce the password rules.

Copyright.gov

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

DBS

Okay at least 6, that's alright i guess. Oh at least one number and one letter, bit dumb but hey not that dumb.

But hiding the fact that it has a max of 20, now THAT is dumb!

Dell

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

Delta

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

DJI

At least 8 and at most 25 characters, of which at least 3 of the characters were not used in the previous password. No more than 3 of the same characters. At least 1 upper case and 4 lower case characters. No more than 3 special characters.

It's not like hashing passwords is a thing or something.

Dutch Tax Authorities

  • At least 8 and at most 16 (!) characters

Fidelity

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.

\<>' and spaces prohibited, upper bound. Passwords of exactly the maximum length are truncated by one character. Unlisted prohibited characters.

FIS Global

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

EON

Must be exactly 6 alphanumeric characters, does not show special characters are not allowed, username is your social security number (easily searchable) and the form is sent over plain HTTP. Did I mention this company applies college entrance exams for Computer Science nationwide in Brazil?

Global Entry

Some characters are too special.

GoDaddy

Her Majesty’s Revenue & Customs

  • 8 or more characters

Okay, fair enough, but after putting in a password with some special characters this message appears:

  • Invalid characters, allowed are: A-Z a-z 0-9 ä ö ü ß Ä Ö Ü ^ ! $ % / ( ) = ? + # - . , ; : ~ * @ [ ] { } _ ° §

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

Hetzner

Max 20 characters, must have one number, one upper case character and one lower case character. You can only use certain special characters. When i asked about it they answer that it's really hard to change it. When i asked if the password is saved as a hash or just plain they send the answer to the technical department this was march 2018.

ING Bank

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

ING Australia

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.

ING Romania

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

Inria

Intel

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 firstname.lastname@youruniversity.fr 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.

Izly by Crous

While not the dumbest password rule, still dumb.

Password must have a length of at least eight characters and contain at least one: number, special char !#$%-_=+<>, capital letter, and lowercase letter.

Jitterbit

"Your password cannot be longer than 20 characters"

LibraryThing

Natalie Weiner
can't sign in because her's lastname is offensive language for the website

Maxpreps

Passwords must be between 8 and 20 characters, and some special characters are allowed. Users with randomly-generated passwords may find it particularly annoying to generate a password that works for their password safe.

Merrill Lynch

When creating a new account they enforce some password rules like: length must be between 8 and 15 characters and there must be one upper case, one lower case letter and one number.

MLB

Max length of 20 characters, no special characters allowed. Pasting into the second password field is disabled even with the Chrome extension Don't Fuck With Paste.

MetLife

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".

Microsoft (work accounts)

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

Mindware
Mindware
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.

MKB NetBankár

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.

Mobi Bike Share

Min 7 and max 8 characters for password! Also to be different than the username: the user name is automatically generated and is based on the surname of the user with some characters replaced by digits :)

Has been that way for more than 10 years.

MobileIron

You can't make this up - no dictionary words, no more than 2 repeating characters, no alphabetic sequences, no whitespace, 3 character sets, maximum of 32 characters.

PagoMisCuentas

A site responsible for protecting your investments limiting you to a four character range with a bunch of other stupid rules? Shocking.

PayPal

PizzaHut-1 PizzaHut-2 PizzaHut-3

Premera Blue Cross

Password must contain 8-30 characters, including one letter and one number. "Special characters allowed" seems to mean a very small handful of choices you can only find through trial and error -_'.@

|Premera Blue Cross|

There are a couple of password limitations when creating a new account on Raiffeisen Bank Serbia on-line banking portal. Password length is limited to minimum 8 and maximum 16 characters. Also, minimum uppercase letters 1, minimum lowercase letter 1, minimum digits 2, maximum consecutive identical characters 4 and first character must be a letter. Oh... And, no special characters!

Raiffeisen Bank Serbia

Symbols. You keep using that word. I don't think it means what you think it means.

Red Hat

A maximum password length of 12. The hidden requirements are:

  • atleast 1 uppercase letter
  • atleast 1 lowercase letter
  • atleast 1 numeric character
  • atleast 1 special symbol (which can not be ^, %)

Rediff

Roll 20

Hmmm.. why are they afraid of double and single quotes in my passwords?

Rushmore

Passwords between 8 and 9 characters are the best.

SAP Cloud Appliance Library

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.

Slovenska sporitelna is the biggest bank in Slovakia. Despite pretty new version of the internet banking (rolled out in 2018), their password policy restricts password to be 16 characters long at most and prohibits any special characters.

Slovenska sporitelna

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.)

Sparda M 1

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

Sparda M 2

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.

Sparda B

„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:

Sparkasse Jena

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 "upgraded" their security and disallow special characters.

Techcombank

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. 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.

MyWorkplace

Your password length is limited between 8 and 32 characters.

Ticketmaster.de

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.

TradeMe

Treasury1

Treasury2

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

Ubisoft

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

United States Postal Service

University of Texas as Austin

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.

University of Windsor

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.

USAA

URSSAF

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)

Vietnam Airlines

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.

Viobank
