As I know we don't need to install any library for ubuntu 20.04 where we can enable by Settings->Users->Authentication & Login.
but when I trying to enable I'm getting an error "Could not access any fingerprint readers Please contact your system administrator for help!"
P:S. I have an inbuilt fingerprint sensor on my machine, but when using lsusb I could not able to see fingerprint driver.
There is no driver available for most fingerprint readers at the moment for most Lenovo laptops. But to be sure you can do a check.
1.Install this package sudo apt install hw-probe
2.Run this command sudo -E hw-probe -all (creates a File with all devices which is located in /root/HW_PROBE/LATEST/hw.info/devices.json)
3.Open the file from the last command: (first type sudo su) gedit /root/HW_PROBE/LATEST/hw.info/devices.json
4.Find the fingerprint reader somewhere at the bottom of this file and if you see "Status" : "failed" then there is no driver installed.
5.The first line of the fingerprint driver is something like this "usb:28ck-58dk" (example)
6.https://linux-hardware.org/index.php?view=search open this and write into DeviceID 58dk (example) and check if the driver in which kernel will be supported.
