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).

Due to Costco's short max password length of 16 characters, I strongly recommend using a password manager to make a random password to satisfy all of these conditions below:

• Use between 8 and 16 characters
• Include at least one lowercase (a-z) and one uppercase letter (A-Z)
• Include at least one special character (e.g. !@#$&) - i.e., any symbol above the 0-9 keys)
• Does not contain blank spaces or the following special characters: < > ,
• Include at least one digit (0-9)

For the record, at least Costco.com has greatly improved after the summer of 2021 - before that, the site used to prohibit copying and pasting passwords, which prevented password managers from working properly. I believe the max password length was also longer before the summer of 2021 (either 20 or 32 characters), but I cannot confirm this since I never took a screenshot.

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

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

Portuguese power distribution company, which requires short passwords (10 to 15 characters), no repetition of the same character, not using the username, the word "PASS" or the word "SAP" in the password, and limiting which special characters can be used.

Causes:

• Your two-factor authentication code must be appended to the end of the password
• Passwords have a limit of 32 characters

Effect:

If your account has a 32-character password and has two-factor authentication, their system appears to cut off the token, making it impossible to login. You must reduce your password to 26 characters in order to login with a token.

• Other issues: allows and encourages the use of sequences like "12345678", SSN, DOB, today's date
• At stake: last 4 digits of SSN, current and past addresses, and detailed work history of millions of Americans, down to how much their paycheck was in the third week of September 2007

It might not be a web site, but that does not make it less dumb. Since many don't know about IBM mainframes, it seems they don't think you need to up the policies.

Default old password policy is: 6-8 characters long, A-Z, 0-9

Over the last few years they have updated their policies a bit, but due to many of their subsystems are incompatible, they can't enforce the new options for safer passwords.

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 attempts. 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.

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.

Max of 16 character oh and please don't use any characters we don'y know how to escape properly also if it starts with ? you may break our wonderful website. What out with your password generator duplicated characters is far too insecure to allow here.

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".

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

Passwords:
