Can I use Google 2FA, Yubikey , DUO simultaneously?
Can we use multiple 2fa?
Overview: This guide describes how to configure Google 2FA, YubiKey, and DUO Security together in the web panel, enabling SSH jump host users to authenticate using their preferred method, and providing flexibility if one device is unavailable.
Google 2FA, Yubikey, and DUO can be configured and set for use simultaneously in the web panel. The SSH jump host user can set all three 2FAs and can use any of them to authenticate depending on the user's choice.
If the User has forgotten to take his Yubikey device, then he can authenticate with the Google 2FA or DUO Security app installed on his phone and vice versa.
