I can't count the number of passwords I forgot. I realised that the day I stumbled upon my myspace account. It tried login in, but couldn't recall the password (it was like 5 years old). So I pressed "forgot my password", and the link to reset it was sent to an old account that I had let die slowly. Couldn't remember the password either, So I pressed "forgot my password", which led me to my first email address created. Needless to say I was locked out too. In the end, I managed to recreate the hotmail.com account, which was deleted after a few monthes, and have myspace give me another password. But I was lucky there!

As of today, I still can't remember what my password was back in the days. and I think it will be the same for the passwords I use now (which are even more complicated, and numerous). Hence the need for a password manager.
