About two-factor authentication & Duo

titleWindows

Windows systems are a little more difficult to set up automatic push from Duo. The description below uses Putty.



Go to the Data section of Connection and add the DUO_PASSCODE variable.



Click Add and your screen should look like the following.



Go back to the Session category, select Default Settings, or whichever session is associated with the HPC system, and press Save.



That will then have Duo send a push notification to your device whenever an ssh session is initiated. Note that you will need a smartphone or tablet for this to work.

Note
titleDeprecation Notice

In order to improve the security posture of the Argon HPC Cluster, it is planned that, beginning August 11, 2021, the DUO_PASSCODE environment variable will no longer be processed by the SSH service for SSH login sessions on Argon. This only applies to sending a passcode prior to session initialization. Let us know if you have any questions or concerns about this change
