Context is that I had to register for a lot of accounts recently and some of the rules really make no sense.
Not name-and-shaming, but the best one I’ve seen recently is I might have accidentally performed an XSS attack on a career portal using a 40-digit randomly generated password…
My community colleges:
Passwords must be 12 characters long, contain at least one uppercase letter, one lowercase letter, a number, and a special character; it must also be changed every 30 days. There was also some sort of alogarithm that checked if your new password is too similar to any previous password you had used, and rejected it if it was too close.
Hilariously, if you had a link to the page the password was supposed to limit access to, you could bypass the password page entirely. As such, I never changed my password.
