Clear text facebook password?

Call me skeptical but an app that doesnt use the iOS Facebook login but instead pops up a Facebook looking window with a clear text password box looks like a scam to me. I wont be signing in using Facebook and I urge others not to either until this app has a proper Facebook login.
