Ever wondered if your WiFi network is secure or if someone's been sneaking onto your connection? It's time to put your network to the test with WPSApp, a tool designed to check the security of your WiFi using the WPS protocol. This protocol lets you connect to a WiFi network using an 8-digit pin number, which is often pre-set in the router. The catch? Many routers from various manufacturers have pins that are either known or can be calculated, making them vulnerable to unauthorized access.

WPSApp uses these known pins to attempt connections and determine if your network is at risk. It employs several algorithms for pin generation and includes some default pins. Additionally, it calculates default keys for certain routers, allows you to view WiFi passwords stored on your device, scans devices connected to your network, and analyzes the quality of WiFi channels.

Using WPSApp is straightforward. When you scan the networks around you, you'll see networks marked with a red cross; these are considered "secure" because they have the WPS protocol disabled and their default passwords are unknown. Networks with a question mark have the WPS protocol enabled, but the pin is unknown. In this case, the app lets you test the most common pins. Networks with a green tick are likely vulnerable; they have the WPS protocol enabled and the connection pin is known. It's also possible that the router has WPS disabled, but the password is known, in which case it will also appear in green and can be connected using the key.

To access some features, such as viewing passwords, connecting on Android 9/10, and using certain extra functions, you need to be a Root user.

Please note: Not all networks are vulnerable, and a network appearing as such does not guarantee 100% vulnerability. Many companies have updated their router firmware to address these issues.

If you find your network is vulnerable, take action immediately. Turn off WPS and change your password to a strong, personalized one.

Disclaimer: I am not responsible for any misuse. Intrusion into foreign networks is punishable by law.

From Android 6 (Marshmallow) onwards, you need to grant location permissions. This is a new requirement introduced by Google in this version. For more information, visit: Google's Android 6.0 Changes.

Some Samsung models use encryption and display passwords as a long series of hexadecimal digits. If you're curious about decrypting them, look for information online or contact me directly.

Note that pin connection does not work on LG models with Android 7 (Nougat) due to issues with LG's software.

Before rating the app, please take the time to understand how it works.
