Take the 2-minute tour ×  Yesterday I went to my cousin's home
and I saw that I'm not connected to his wireless (for internet
access). Then I have looked up the list of wireless points. I
have found his name and clicked it connect, I have entered his
password (which I know) and it didn't connect. Then I've asked
him whether he changed the password and he told me that he
didn't and it is because just the wireless device is closed. So
I thought, could it possible that the password I have entered
was "taken" by the guy next door?  I don't know whether the
plain password is send to the device. And I think you call it
Access Point.  share|improve this question  3 Answers 3  No,
WPA2 Passwords are not sent in plaintext. If this were the case,
anyone could deauth you from the network and sniff the password
directly from reconnection handshake.  They can, on the other-
hand grab the encrypted handshake and crack it using aircrack-
ng. Other than a faraday cage, you really can't prevent this.
