How can I see the name and password of my wifi using ethernet cable connection

Question

How I can retrieve the name and password of wifi. I am connected to a router via cable. Is there any way in ubuntu to get this information?

Solution

If you want to retrieve the Wifi password of a known connection. Simply go to:

/etc/NetworkManager/system-connections/

You will see all the saved connection profiles there, and you open it with root previliege:

sudo cat some-ap-profile

The password will be in the [802-11-wireless-security] section, see the psk= part:

[802-11-wireless-security]
key-mgmt=wpa-psk
auth-alg=open
psk=HERE-IS-THE-PASSWORD

Passwords in plain-text??? O.O

@ByteCommander Yes, in plain-text, the only protection is the root access, but if you mount it on another system as a normal data drive...
