Can Mint 19.1 support Fingerprint and card logon. What software and devices do I need?

This is for many users on a network of computers with Linux Mint

Thanks for your help.

Mint can "probably" support card (smartcard) recognition using opensc. Login is a different story but could probably be done. CentOS can do it so don't see why Mint couldn't. Can't speak to fingerprints, I've never used this technology on Linux.

Thanks it is in the software manager. I presume using this you can change to the user of the card.

Opensc allows the OS to recognize the card. Tying the user's card to a user's login is different. What do you mean "change to the user of the card"?

Want to use the card to change user and ensuring the card gives the password for the user to access and change files

to state the obvious first, you are going to need either a fingerprint reader, or smart card reader for each system.

I've gotten Linux Mint 19.x cinnamon and whatever their default login manager is to work with my fingerprint reader that came with my laptop.

I do not have Mint installed anymore, and I do not remember exactly which page I googled for step by step instructions to get the finger print login to work, it did use pam and I have a 138a:003f Validity Sensors, so I needed to get a fix for that one,

Just google / use your favorite search eng and look around on the net for finger print reader log in MINT Linux, you should find a few hits with instructions.

So, yes it is possible to use a finger print reader to login to MINT. I have a smart card reader too, but no smart card to test it with.
