I have in the past suggested RoboForm2go as a wonderful password manager and I still stand by it. But another has come to my attention called LastPass which is an online password manager. What I like about it is simple, you don't need to carry your thumb drive with you and your passwords are available from any location & computer as long as you have internet access. It is easy to install and takes only a couple of minutes and signup is free. Once installed you set a master password and now it is the only one you have to remember. It will also sync to any other computer you have it installed on.
Lastpass is also available for most browsers but at the time this blog is being written it isn't for Opera yet. It can do everything Roboform can do and more. It will even complete all the forms needed to buy goods online if you have stored your home address, telephone number and credit-card details in the vault as well. LastPass puts all of your individual passwords behind one master password. When you type in that master password, LastPass can then automatically log you in to any web site you visit with saved login credentials. LastPass syncs passwords over the Internet, so all your saved passwords on your work computer, for example, will always be synced up on your home computer. With Lastpass you can afford to create random, non-guessable passwords and forget about them. You can download Lastpass at: https://lastpass.com/
Since most of us have several passwords this is a must for our protection while on the net. I highly recommend it.
