Using MACs' airport to connect my iphone with wi-fi...want to setup password

[theFranchise25]

Ok,
I turned on my airport on my mac and im using my iPhone to connect to it using wi-fi. So that way if someone is on the internet with the mac (using ethernet cord) i can still browse the web, cydia, etc on my iPhone. how can i setup a password on my mac so no one else in my apts can use my mac to connect...

If you enabled internet sharing on the Mac's Sharing preferences pane, when you picked what connection it would broadcast, you have to click on the Options button to enable a passphrase. It can only use a WEP-level security though, not WPA or WPA2 which is more secure.
