Been experimenting with some OTP solutions (pam-oath, pam-obc).
Anyone used/experimented with them on the Proxmox web gui?
I'm thinking pam-obc would be the better course of action. It delivers it out-of-band via email, sms, aim, etc, whatever. Modifying proxmox wouldn't be necessary in that case.
just wondering what your thoughts / experiences are/have been.
