Yes, I do same password + number, counting up.
Boyfriend once had to change his password at work and included the f-bomb in the new password. That's how he learned that his workplace monitors his keystrokes. Oops. That was an embarrassing conversation with HR.
Not a very secure password then is it? I think IT should win this one (Jesus, did I just say that?).
My work password root was bad language and I updated it with 3 numbers (ie 111, 222, 333, 444 etc) every 90 days and had a sticky with the current 3 numbers on the monitor (40", owned by me, just because, and it did a good job on synthesizing 4K from 1080p).
They required that the password did not match the last 13, so sometimes I dropped it back to the 2 number variations. WTF, if your system remembers 13 old passwords, that has gotta be hackable.
ON topic- I had a close colleague who was fired for searching a word in German (not a language he knows, trust me ) that was apparently a bad word in German. So uncool.
His boss, bosses-boss, bosses-bosses boss, put in an effort not to loose him, but HR had a bug up their ass, and he was canned. Now happier at another place.
Not a place I want to work again (good reminder, now that I'm FIRED from that place).
ON topic- the old workplace has instituted ID badges (20 people max) because the SemiBigCorp policy. If I had been there as the policy was instituted, it would be really petty, but a clear reason to FIRE.
