Recover your wifi password, if you modem has the default password you can use this app to recover the passwords. Never lose your wifi password again this app only works for default password in some modems.

Answer 2

I don't think there is a real app that is geared towards finding a wifi password, it is like hacking the account.  I might be wrong though but I personally check this in the past and there is none.
