Fingerprint detection issue in GUI

So far everything for fingerprint is successful, except logging in. Ive tried LightDM and SDDM, both of which refuse to either acknowledge i have a finger, or that i have a sensor whever they please.
Though I have added the following to get it working everywhere except login managers:

auth		sufficient  	pam_unix.so try_first_pass likeauth nullok
auth		sufficient  	pam_fprintd.so
