Windows 7 Tip: 
Its very difficult to remembers all of your passwords, the easy options to remebers them is using the same password each time or writing them down on paper or in a spreadsheet but that one i not so secure. In fact, security experts strongly warn against these options as they leave you vulnerable to online theft. So am here posting some of the best password managers that can help you to remember all you password safely.
KeyPass Password Safe: KeePass is a free, open source, light-weight and easy-to-use password manager for Windows and mobile devices. It will store an unlimited number of passwords and will automatically fill username and password fields, or you can fill them yourself with copy-and-paste or drag-and-drop. And, since it’s open source, there are several unofficial projects that bring KeePass to other platforms like Mac OS X, Linux, and Pocket PC.
Password Manager Plus: The Billeo Free Password Manager Plus toolbar works with both Firefox and Internet Explorer, and allows you to store not only passwords but credit card numbers and online account information, and can autofill your information as you shop online or paying bills, for example.
RoboForm 6.9: RoboForm makes logging into Web sites and filling forms faster, easier, and more secure. RoboForm provides storage for all types of information and complete automation for filling out forms on the web. It gives you several encryption options, enables true “one-click” logins, will generate strong, random passwords for you, can handle complex web forms without being “trained,” and that’s just the tip of the iceberg. If you want it, RoboForm’s probably got it.
RoboForm also has Windows Mobile, Pocket PC, Palm, and Symbian versions too, but for those of us without handheld computers RoboForm brings RoboForm2Go, a portable app designed to live entirely on a portable storage device like a pocket USB drive. This lets you bring your whole collection of secure information, plus RoboForm’s automatic form-filling magic, anywhere
Clipperz: Unlike most password managers, this solution is online — so you can access it anywhere. And it stores more than passwords — credit card numbers, account numbers, anything really. Storing passwords and other confidential information online can make someplace nervous, but Clipperz uses an encryption method that means not even Clipperz knows what it’s storing. This is a good solution if you need access to your passwords from multiple computers, rather than just one or two.
Password generator: This is a little bookmarklet that combines your master password with the site’s name to create a stronger password, and one that is different for each site. Very handy and simple.
Password Hasher: This Firefox extension generates strong passwords for you by scrambling your master password with the site’s name. The passwords generated by this extension are better than any you could come up with yourself.
