Anyone get these from time to time? You wake up the iPad or iPhone and get asked for your password at the home screen. Most of the time I actually need to use the device immediately and don't have time for that nonsense so I hit cancel. A few times I've entered the password, which seems to make it stop doing that for a while, but it inevitably asks again at some point. It would be nice if iOS would tell you WHY it's asking you for your password. People who aren't familiar with the iOS security model might rightfully assume it's an app trying to steal your Apple ID password!
