I want to share a little anecdote with you...
Last Friday, someone managed to hack my friend's Ebay password. (Apparently, this happens all the time at Ebay.) Inside my friend's Ebay account, the hacker got my friend's e-mail address. My friend used the same password for Ebay and e-mail, and voila, the hacker got access to my friend's e-mail account too.
And because my friend used the same basic login structure for several online accounts--first initial plus last name, full name without a space, et cetera--the hacker got access to other accounts by just trying the login pages for major companies, e.g. AT&T. (Of course, the hacker didn't spend his own time doing that; he used computer programs.)
Nastier still, the hacker read e-mail in my friend's Inbox and Sent Mail folders and sent fraudulent and embarrassing (i.e., pornographic) e-mails to all his correspondents.
Experts advise you to vary your logins and passwords. I never listened until now. Today I changed all of mine. And of course I had to write them down, because I could never remember them all, so now I have a piece of paper I absolutely cannot lose.
It's hard to come up with tons of logins, so I used my drag queen name. "My drag queen name"? No, gentle readers, I don't have a drag alias. To get your drag queen name, you pair the name of your first pet with your mother's maiden name. Then I started using other people's pet names, with other people's last names. Soon, I had lots of fabulous new logins.
