✖ WiFi Password Viewer doesn't discover the WiFi passwords!
✔ WiFi Password Viewer shows only the password of WiFi networks to which you have been connected!
Warning: ROOT access is required.
Some devices (e.g. Samsung) encrypt WiFi passwords, so that no app can show them clearly. To show them, please, following the instruction in the Welcome Alert Dialog in the app or here: android.stackexchange.com/questions/95923/decrypting-wpa-supplicant-conf-on-samsung-galaxy-mobiles. Thanks for collaboration.
N. B.: it's impossible to make an application to show WiFi passwords without requiring root, as it has to read a file that is in an inaccessible location without administrator privileges (/data/misc/wifi/wpa_supplicant.conf).
For any request, report or other, please, send me an email before leave a negative review (email@example.com). Otherwise, If the application helped you, consider to leave a positive review. Thanks for your support.
