TouchID doesnt work

It sets my iPhone 6 plus into a cycle requesting Touch ID over and over again at least 3 times upon login. You have about half a second to touch something before it asks again. Was able to turn it off after a series of logins but after waiting a long time for Touch ID to be implemented its disappointing that it doesnt work.
