Reworded rules for clarity:

  1. Min required length must be 8 chars (obligatory), but it should be 15 chars (recommended).
  2. Max length should allow at least 64 chars.
  3. You should accept all ASCII plus space.
  4. You should accept Unicode; if doing so, you must count each code as one char.
  5. Don't demand composition rules (e.g. "u're password requires a comma! lol lmao haha" tier idiocy)
  6. Don't bug users to change passwords periodically. Only do it if there's evidence of compromise.
  7. Don't store password hints that others can guess.
  8. Don't prompt the user to use knowledge-based authentication.
  9. Don't truncate passwords for verification.

I was expecting idiotic rules screaming "bureaucratic muppets don't know what they're legislating on", but instead what I'm seeing is surprisingly sane and sensible.

  1. Don't truncate passwords for verification.

It needed to be said. Because some password system architects have been just that stupid.

Edit: Fear of other's stupidity is the mind killer. I will face my fear. My fear will wash over me, and when it has passed, only I will remain. Or I'll be dead in a car accident caused by an AI driver.

I've seen sites truncate when setting, but not on checking. So you set a password on a site with no stated limit, go to use said password, and get locked out. It's infuriating

Years back, I had that happen on PayPal of all websites. Their account creation and reset pages silently and automatically truncated my password to 16 chars or something before hashing, but the actual login page didn't, so the password didn't work at all unless I backspaced it to the character limit. I forgot how I even found that out but it was a very frustrating few hours.
