RouterPassView is a lightweight, portable utility, which is able to recover lost passwords to router config files, 'if' there is a backup stored on the computer. As RouterPassView is portable, you can simply drop the .exe file on your hard disk and click it to run, and you can also run it on any workstation directly from a USB drive.The app s interface is a standard explorer style window with a simple layout. From it, you can open the router configuration file, by using the file browser or drag-and-drop. The list provided shows the server, password, item type, and user name. RouterPassView also supports grabbing passwords from IE windows, opening the router web interface, and you can use a search function when working with large amounts of data. You can also copy items to the Clipboard, as well as toggling between table and text mode (ASCII or hexadecimal).
