I am needing to do some work on Linux servers that require 2-factor authentication using a PIV card. The instructions I was given are based on PuTTy-CAC but I woild like to use MobaXterm. I wasn't able to find equivalent settings ("CAPI Certificate") in MobaXterm.

Is there any way to use MobaXterm where 2-factor authentication is required and how?


Load your CAPI keys into PuTTY-CAC's Pageant (SSH signature agent). MobaXterm supports using Pageant for authentication (partly because its SSH client is indeed based on PuTTY). This also works with a few other clients, such as WinSCP or Bitvise Tunnelier.

  • That sounds nice but all I'm able to get off my PIV card is the private but not the public key which Pageant requires – amphibient Jun 6 '18 at 20:38
  • Do you mean the opposite? And Pageant doesn't require the private key any more than PuTTY itself doesn't. It requires the ability to sign, which the "-CAC" version can obtain via CAPI. – grawity Jun 7 '18 at 5:18
