You don't need to worry about keyPress events in this case. TextInput conveniently dispatches an enter event when user presses enter.

<mx:TextInput id="passwd" displayAsPassword="true" enter="submit()"/>

Script:

private function submit():void
{
  var pw:String = passwd.text;
  //submit the login here.
}

This is applicable for spark TextInput also.
