I need to share WiFi password with my notebook, because it has better antennae. Is there an open source Android app that allows see the WiFi pass of existing connection?
On Android devices, WiFi passwords are stored in an area no "normal" app can access (if you are interested in details, it's file system permissions behind this). Thus, if an app shall access stored WiFi passwords, it requires root access. Without root powers – no way, to my knowledge not even via ADB¹.
If you take a look at my app listings on WiFi Password Recovery you will see that all those apps require root access. And if you have root access, you don't need an app for that – you can simply access the
/data/misc/wifi/wpa_supplicant.conf file directly and see the password (
psk) for each network (
ssid) you connected, plain text.
That said, I don't know of any up-to-date open-source app for this.
¹ only place that could work would be examining a full ADB backup, but I doubt it's in there
