I have screwed myself over numerous times, waiting until the last minute until a mandatory work password change... on a Friday. Then I come back to work on Monday and I can't recall what the hell I changed it to.
This time, I had 5 days to spare, so I did it yesterday. And when my work email forces me to change my password, then I change all my other email passwords, too.
To make things easier (because we have to enter our passwords at work; we can't use authentication apps, although after we sign-in the first time, we can use our ID badges to swipe in on work computers), I tend to use the same password for all my accounts.
I know: that sounds terrible - but I change the phrase to Leetspeak, add a capital letter or two, and add different prefixes and suffixes, based on which email accounts.
( how it works... it sounds complicated, but it's actually quite easy, once you get the hang of it! )
This kind of patterned password changing across multiple accounts has made my life so much easier. Seriously.And never, ever change your work password(s) on a Friday - unless you work the weekend, so you have some days to practice the new password(s)!
I hope this helps people! It has helped me a lot.
