Yubikey two factor authentication for ssh

March 8, 2019    Tags: yubikey  2fa  ssh  yubico

Yubico

After my successfull sudo test I was interested in 2fa for ssh. As a systemadministrator you are always scared about secure login just for you/your team.

Also ssh 2fa via yubikey is pretty straight forward. It needs some more work than just the sudo case but here we go.

Yubikey for sudo 2 Factor Auth

Dec. 7, 2018    Tags: yubikey  2fa

Yubico

Some days ago I thought about testing two factor authentication (2FA) with Yubikey. Yubikey is a hardware security key which can do a lot.

How to test 2FA on a local machine if you don’t want to log you out or destroy anything important? I decided to implement 2FA for sudo command with yubikeys U2F feature. Be aware: This does not work for ssh.
