RIFT has been dealing steadily with account security issues since launch, so the upcoming authenticator service is no surprise to players. Using a digital authenticator service, players will very soon be able to use their Android mobile devices for authentication services -- but carefully note the "soon," as the service isn't yet ready for prime time.
Currently, using the authenticator will prevent players from logging in, as the code for using said authentication isn't yet in place. A new launcher will be put into place for the game later today, allowing players with Android devices use of the authentication service. While the current release is only for the Android platform, code for the iOS is being finalized, meaning that iPhone and iPad users won't be left out in the cold. So if you're playing RIFT and want to have a little more random number to go with your login, you'll soon be able to do just that. (But not quite yet.)
