![]() The default pin on they yubikeys is 12345678 for the PUC. yubico-piv-tool -action verify-pin -P xxxxxx Use this command to check that the PIN on the Yubikey is what you think it is. Ubuntu Servers: sudo add-apt-repository ppa:yubico/stable -yĭebian Servers: sudo apt-get install libpam-yubicoĬentOS/Fedora/Arch (EPEL repository) sudo yum install pam_yubico However, if you are happy to connect to the servers using your Yubikey and remembering its security PIN, you do not need this. If you wish to connect to your servers via SSH using the one time password (OTP) functionality of your Yubikey, you will need to install this on your servers. ![]() Ubuntu users should use the repository: sudo apt-add-repository ppa:yubico/stable -y You do not need this on servers you wish to connect to via SSH. Your local client computer will need this tool for interacting with your yubikey. You only need this on your local computer's that you will plug the yubikey into (e.g. Install the open smart card reader which will allow us to talk to our yubikey. using one-time-passwords OTP) Install Card Reader Software (Client) You don't need this if you wish to log into remote servers using a PIN to unlock your SSH private key, but you will need it if you wish to use the button to authenticate instead of the PIN (e.g. Enable Yubikey For Gmail 2-factor authentication.You just need to remember to take it with you, and don't lose it!

Just as you use a key to open your front door, you should use this key to gain access to your servers over SSH. I believe the Yubikey (From Yubico) is probably the best solution (for now) that you can have if you wish to ditch using strong unique passwords for everything.Įssentially it is just a clever smart card that you can plug into your computer, that can be used for private cryptographic keys of various types, but I like to think of it as a physical key to the digital world.
