check in system settings or with fprintd-enroll

other things to check fprintd-list

[default-student]

add them for screen unlock and sudo like this:
https://unix.stackexchange.com/questions/655203/how-do-i-implement-fprintd-into-login-in-kubuntu
sudo apt install -y fprintd libpam-fprintd
sudo pam-auth-update

[default-student]

sorry for the messy write up, but i think it should be documented

[default-student]

do note that there are further issues on linux with finderprints.
kubuntu with sddm cant login when having the fingerprint activated using pam-auth-update.
check https://askubuntu.com/questions/1307437/can-not-login-to-sddm-using-fingerprint-on-kubuntu-20-10
