My nerd had started to use Last Pass some time ago and when I once again locked myself out of an account, I decided it was time to find out more about it. Last Pass is a password manager. Their tag line is "The Last password you'll have to remember". That sounded good to me, so sign me up!
First thing I found was that it was easy to get started. I downloaded Last Pass from their Web site and pretty much let it do it's thing. I chose the option to import my saved passwords from my browser. I've been able to use it on all the browsers that are on my computer (Chrome, IE 9 and Firefox). When I start up, I log into Last Pass. Anytime I go to a Web site that requires a password, if it's not already auto-filled, I just click on the Last Pass icon and choose which user name to use and it auto-fills. When you go to a new site and create a password or enter a password that Last Pass does not have saved, you will receive the options to save password, not now, or never for this site. I don't use Last Pass for things like my PayPal account or my online banking. Pretty much anything else is game.
I find it very helpful to use Last Pass. I spend a lot less time trying to remember which password I created for which site and waiting for password reminder e-mails to be sent to me. Now I just log in once and I'm good for the day.
