Password Commander fully supports all common browsers, including Internet Explorer, Opera, Netscape Navigator, Maxthon, Mozilla, Firefox. It does not just fill in password and login fields - it can automatically fill (autofill) in all required fields for websites and any Windows application. Can you think of a second password manager capable of that? You will love this feature, whether you have only a couple of passwords or couple of hundreds. Password security is another important issue where Password Commander stands out. It has an open architecture model, supporting third party encryption plug-ins. So, if you are worried about your password safety, you can install free PC Plug-ins PowerPack that offers forty encryption methods, some of which are being employed by the US Department of Defense. Encryption professionals can even create their own plug-ins, because open SDK is available. Just use strong encryption algorithms ( i.e. Blowfish or IDEA) and even if the a crook steals your PC or password storage media with Password Commander, it'll take him or her about five hundred years to pick your passwords.
