After setting up fingerprint sudo prompts for both password and fingerprint

After I set up fingerprints on my system, sudo began asking for both password and fingerprint.

sudo echo doot                                                                                              ✔ 
[sudo] password for partkyle: 
Place your finger on the fingerprint reader
doot

Is this intended? I would prefer only to need 1 method, and to use the fingerprint first.
