The main purpose of the WiFi WPS WPA Tester app is to test the security of Wi-Fi networks by checking their WPS protocol vulnerabilities. It helps users determine if their wireless network is secure or if it can be easily accessed.

The app tests Wi-Fi security by attempting to connect to the network using various default WPS PINs. If successful, it indicates that the network is vulnerable to unauthorized access.

If your network is marked as vulnerable, it's essential to change the default WPS PIN or disable WPS altogether. This will enhance your network's security and prevent unauthorized access.

While the app can test security through WPS exploits, it is important to note that using the app to access unauthorized networks is illegal. Always test networks you own or have permission to access.

To improve your Wi-Fi network's security, follow these steps: 1. Change the default router username and password. 2. Disable WPS and UPnP features. 3. Use a strong WPA2 or WPA3 encryption key. 4. Regularly update your router firmware.
