Forgetting a WiFi password on your Android device can be frustrating, especially when you want to connect another device. Fortunately, there are ways to retrieve a saved WiFi password on Android:

1. Rooted Android Devices:
   If your device is rooted, you can access the saved WiFi passwords through file explorers like ES File Explorer or Root Browser. Navigate to the root/data/misc/wifi folder, and look for a file named wpa_supplicant.conf. Open the file using a text editor to view the saved WiFi passwords.
2. Using ADB:
   If your device is not rooted, you can use the Android Debug Bridge (ADB) on your computer to access the WiFi passwords. Connect your device to the computer, enable USB debugging in developer options, and run commands to access the WiFi passwords stored in the device.
3. Third-Party Apps:
   There are several third-party apps available on the Google Play Store that can help you retrieve saved WiFi passwords on your Android device. Apps like WiFi Password Recovery or WiFi Password Viewer can display the passwords once the necessary permissions are granted.

It's important to note that accessing WiFi passwords without permission is illegal and unethical. Only use these methods to retrieve your passwords or with explicit permission from the network owner. Protecting your WiFi network with a strong, unique password is crucial for maintaining security and preventing unauthorized access.
