If you have an Android smartphone with OS lollipop or higher, or your device is rooted. Then you can crack “WPS enabled” wifi networks using following Applications

1. Androdumpper.
2. WPS Connect.
3. WPS app.

This will help you to crack the password and get connected. But only rooted devices are able to see the password. For non rooted devices there is an alternate using the route gateway access using their respective address like (192.168.1.1) mostly. For authentication use “ADMIN ” as username and “password” or “admin” or “12345 ″ as password. Then find the password in advance wifi settings There is no assurance of cracking every router. Only routers wifi will be cracked whose WPS pin is present in the directory of the application

Are these tested methods?

Also, cracking the wifi does it mean that you have only access to its connection or you can also view the other devices connecting to it?
