I’ve had just as many permutations of my username as described in the OP.
Regarding passwords: Several tools I use require that a) the password must be changed every 90ish days, b) cannot be similar so “Mypassword1001” followed by “Mypassword1201” will not be allowed, c) CANNOT BE PASTED INTO THE FIELD. So it has to be something typable.
sh345@@%^*sfrEtW (just random crap from my keyboard) is only good if you can manage to type that without messing it up.
1Password, the vault we use, has the ability to type a password into a web field if you can’t paste it in - but this one piece of software doesn’t even work with that!
I remember one login - and this was a Federal system - where the rules changed to “14 or more characters, some lower, some upper, some numbers, some special”. Again it was something I needed to type in, and I came up with a 15-character keyboard pattern that would be semi-rememberable.
And nothing worked.
I finally called the help desk, and was told “Try EXACTLY 14 characterrs”, and “such-and-such special characters won’t work”.
Really? Really? You don’t think “14 or more” and “a special character” might coulda used a little more detail?? Last I looked, “15” meet that description, as did the parenthesis or whatever special characters I was trying. It’s a subject of a long-running rant in our household: If there are password rules, TELL US WHAT THEY REALLY ARE.
Another website mandated some strong-ish password. I’d do a password reset, it would accept the password, then I couldn’t log in again. Lather, rinse, repeat.
Somehow I found out that there was an undisclosed limit to the number of characters. So I’d type in something like MyPW#123#456$789, type that again to confirm, and the system would say “MyPW#123 sounds good to me!!”.
And the time I got locked out of my laptop for a week because corporate policy mandated a much longer password to encourage phrase use.
So I changed mine to something like “mackdonna handheld shoehorn butterhorse”.
And it worked. For 24 hours. Then I was locked out.
The help desk said I was not the first person this had happened to; apparently the issue was the spaces. “macdonnahandheldshoehornbutterhorse” would have worked.
