[Mr.Kurd]

Please tell me you are trolling...

Actually wifiphisher is a best choice because you can make a fake wifi like a keylogger.
And that above isn't troll, you can try it yourself if it didn't worked, you made a mistake somewhere so be careful with the first way .

Ask to use their wifi? I think that would result in some follow up questions OP wouldn't want to answer. Second, use your head @Mr.Kurd physically attacking someone like that is assault, and will likely end in jail time. He wants to do this quietly.

Yeah, You can ask them.
I have my neighbors password .
And the Second way not for all people, A long time ago Three of my friends were attacking a friend without reason and when they reach the home, they were asking him to forgive them, If he didn't, they started hitting him again until he forgive them .
