Re: Nothing wrong wirh reusing passwords
About 8 years ago a system I use regularly started enforcing password changing via AD. There was much grumbling as the change timer is about 3 months and the old password cannot be a prefix of the new password which immediately rules out changing totalBollocks to totalBollocks1. Then someone pointed out to me that adding numbers into the password means it's treated as a completely different password. Thus:
are all unique passwords.
This has served me well for the last 20 odd password changes.
