check in system settings or with fprintd-enroll

[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
