Final answer:
To view the WiFi password on an Android device, one needs root access as the information is stored in a secure system file. It is not possible for non-rooted devices to view this information directly, though rooted devices can use file managers or third-party apps to access it. Newer Android versions allow sharing through QR codes without revealing the password.
Step-by-step explanation:
To view the WiFi password on an Android device, you must have root access, as the password is stored in a secure area of the device. For non-rooted phones, it is generally not possible to view the network password. However, if your device is rooted, you can find the password by using a file manager to navigate to the /data/misc/wifi directory and opening the wpa_supplicant.conf or networkHistory.txt files. These files contain the network SSID and passphrase. Alternatively, there are third-party apps available for rooted phones that can retrieve and display saved WiFi passwords.
For recent Android versions, sharing the WiFi network via QR code has been introduced, allowing users to share network access without viewing the actual password, ensuring security protocols are followed.
