I was visiting a web site recently that I haven’t visited in many, many years. I tried a few old passwords I used to use before I started using a password storage system, but no luck. I was defeated. Barred from entry into this site. But wait, they have a “Forgot Password” link; knowing I will soon have entry into the site, I confidently click on that link (after entering what I believe my username is). Boom, a few seconds later, I have an email from this web site that I will not name. Opening the email, there it was. The password I had created from ages ago. Head-slap.
