I’ve recently successfully installed and configured Duo Unix using pam_duo on RHEL7 with pubkey authentication method.
My department would like the ability to bypass 2FA for subsequent SSH logins by the same user. So far I’ve only been able to find the “session awareness” feature through the ‘Duo Network Gateway’. Are there other solutions like custom scripts or custom PAM stacks that can accomplish this? I’m not sure we can utilize the network gateway feature just yet, as my department is not the duo admin for the campus.
