Works ok on some sites but others give problems. Twitter for instance adds but can't complete as the verification notification never seems to get sent to the app. Also there is no way to back up the security accounts, so if the phone is lost or damaged then the keys go with it.

No need to enter six digit codes anymore! Revolutionary idea.
