Thanks for the pointer. Unfortunately, I'm still having that danged pup-up at least 5 times a day. Every app has Facebook switched off in Settings. On the Facebook Settings page, there is no list of apps to deal with, but I went into every individual app Setting to look for any reference to Facebook and dealt with it there. Still the request for a Facebook password keeps coming. It's driving me a bit mad. Anybody else got any ideas? Is Facebook just so integrated into iOS that there is no way to stop these requests from coming? Surely, I'm not the only one with iOS devices and no Facebook account.
