Hello ! I enabled fprintd with the fprintd package and added fprintd-service-type service to my configuration. This works : I can enroll and verify my fingerprints with success.
However, fingerprints cannot be used to login from GDM, nor from sudo or any other authentication tools. As far as I understand, this needs some PAM configuration to be added to existing config files. For example, if I want to be able to use fingerprints to authenticate with sudo, I would need to add to /etc/static/pam.d/sudo: auth sufficient pam_fprintd.so I came across the "pam-extension" function browsing the guix source code but I am not sure on how I can implement that in my system.scm... Is there a tutorial or an example snippet I can use to achieve that? Thanks, Nicolas
