Iphone 5s TOUCH ID option is gone

It might be bugged or something please i really i want it back:/

Make sure that you go to settings>touch ID& passcode (I'm assuming that you do that but just making sure). If that is not the issue you have two options. 1. Turn off your phone by holding the lock and home buttons until the phone is shut off, it will immediately go to a black screen. Turn on your phone and check to see if the option is back. 2. Go to an apple store and visit the genius bar to have them look at it, they should be able to fix it.
