I'm a computer geek according to my brother. I do work in the IT field. Thus I have a lot of passwords that have to be changed often. These passwrods also have to meet certain security requirments like being more than 8 characters with at least one capital andone lowercase letter, one number and one special character (@#$%&*). Oh, and to be secure, you are not supposed to write them down.
My trick is to come up with a 2 word phrase that seems to fit the current situation. Like Snow Day. I replace the o with a zero, the a with @ and capitalize the S and the D: Sn0wD@y After I had my Lasik procedure, I set my password to N3wSi&ht (New Sight). This helps me remember it the first couple of day.
Don't tell anyone, but I do try to keep a list of past passwords. It stays burined on my purse in my portable address book. I don't label or title it. I also keep a speradsheet with the usernames and current passwords of the various webistes I have created an account. I keep that on my little USA thumb drive. Works for Me.
