Open Free Wi-Fi Password will display all the open Wi-Fi networks around you in a moment. You just have to open the app. If you can see a green lock unlocked, click over it, and you will be redirected to the Wi-Fi settings. After this, just select the open Wi-Fi network you are willing to connect. You won't need Wi-Fi password any more. Just connect to the open Wi-Fi.
Pretty simple to use, and a very clean app. Contains few ads.
