Challenge-response support doesn't look promising for Bio?
pam-u2f works- detailed here: https://developers.yubico.com/pam-u2f/ (:warning: read up and know what you're doing before following my balmy instructions, a botched pam config will lock you out and /etc/u2f_mappings
is not readable from an encrypted drive.)
These steps worked for me on Linux Mint.
Install and create mapping for your user:
sudo apt install libpam-u2f
pamu2fcfg -uYOURUSERNAME | sudo tee -a /etc/u2f_mappings
Edit the pam config:
sudo nano /etc/pam.d/common-auth
Add:
auth sufficient pam_u2f.so authfile=/etc/u2f_mappings
Right after:
# here are the per-package modules (the "Primary" block)
Pop a new shell and run "sudo ls" to test. Practise touching the key in just the right way. 3 failed attempts will cause a lockout and you'll have to fire up Yubico Authenticator to unblock. This seems an odd design choice... I guess you can bruteforce a fingerprint.
I think "sufficient" is... sufficient. I have my 5Ci set up with pam-u2f, too, but anyone can touch that and log right in to my computer if I leave it plugged in.

No worries- you might also find this interesting, though I had to modify a fair bit to work with my setup: https://gist.github.com/seanlinmt/2530b60e108a0d60d0faed4277e86595
