I can't access the settings Touch ID and passcode on my iPhone six

[iMore Question]

I can't access the settings Touch ID and passcode on my iPhone six because I forgot my 4numerical digit passcode that I set after I set my Touch ID with my left thumb print. How can I use my thumb print to access the settings Touch ID and passcode to disable the passcode and Touch ID ?
