Securing your Wifi Tether signal?

[Konabob]

Ok, I am rooted and bloatware free. Very easy thanks to you guys...

I have installed Wifi Tether and am playing around with it. It works great, but I don't see anyway to secure the Wifi signal. If I am sitting in an airport and turn it on, what is to keep 4 or 5 other people from discovering the signal and logging on and watching movies on my signal?
Is there a way to set up a password, or to restrict which devices can connect?

Aloha,

You can enable WEP security in the settings

As in Settings->Change Passphrase

Ok, that makes sense. Thanks!
