Oh this is clever, I’ll use that next password rotation so that my password doesn’t change in effect. We must change every 60 days where iWork, and it doesn’t work well so some systems still use the previous password, some still use 3 passwords ago, etc. It’s random though, you never know in which systems the password change will take and in which it won’t)

Worse is when you're developing software against those other systems, and within a few minutes of logging in, your account is now locked out.

I went to a college with that problem. After your mandatory password change, any device autoconnecting to wifi would trigger a lockout. Since the same password was also use to log into network computers, there was no way to visit the webapp to unlock your account.

Unless you had data on your smartphone or had a friend who was logged in, you were SoL.
