This is more a time saving feature. also would be useful for recovering forgotten passwords. Especially for users who create different passwords for each web site etc. :)
I'm sure the above could be coded into the program as it's really only a registry scan that would be required. I seem to remeber I purchased a program a couple of years ago that scans thew registry for passwords, so it must be possible.
Also be able to store the password in the cloud so that if passwords are forgotten and you are unable to access your computer, you can recover the password via another computer.
