With over 350 (nearly all unique) passwords, this gives me an additional layer of security, and I can access them from any device/location, and don't need to remember them. No worries about someone figuring 2 or 3 re-used passwords out and then having access to my whole life, or writing them down on/in something that can be lost, stolen, or damaged/destroyed. I can use it from any browser or as an app on my phone, and so can the rest of my family. All we need is to know the Lastpass password and the one for the primary email account. A God-send!
