I am connected via wlan to the internet. I was wondering where my password is saved on the raspberry pi. Once I saw it in plain text somewhere. I thought it was under
/etc/wpa_supplicant/wpa_supplicant.conf
But this file is empty. I tried
/etc/network/interfaces
as well. This file is not empty, but there is no information about my password. Then I tried
grep -r -i "MY_WLAN_NAME" ./
and
grep -r -i "wlan0" ./
without any proper results. Do you have any idea where my password could be located at, or at least how to find it?
Further information: I am using a raspberry pi 3 model b; operating system: raspbian.
