If you haven’t heard of or tried LastPass yet, let me tell you.. it is amazing.
After setting up a free account (the premium membership at $1/month is needed for mobile device usage) and creating your master password, LastPass will help you save all of your website passwords, credit card information, and virtually anything else you use online frequently. LastPass encrypts everything which is accessible by logging on to your account, or even better, install a plugin/add-on into your browser.
When you login to a site, LastPass will ask you if you want to save the site. you just click ‘save site’ and bam… done. Don’t have to remember that one again. After you have added all of your passwords you can throw away that cluttered sheet of scribbled passwords! Awesome.
