I know, for example, that Putty-based terminal seems to handle this while the Rebex one does not. But what about the built in SFTP and SCP clients? Not sure if that is a custom piece of work or based on some other open source code base.

Hi Andrew,
which version of Royal TS are you using? The latest versions should handle MFA requests in rebex based terminal and SFTP/SCP connections.

The latest 5. (Not near my PC right now for exact version). Windows-based. It simply continues to prompt for credentials. Now that i think about it, could it be a weird interaction with the existing uid/pws set up? Pre-duo? Something have to change there?

I can’t really tell. We have tested MFA prompts - not sure if DUO was among those but the implementation/prompts are quite generic. I suggest you double-check your configuration, maybe also test with PuTTY and rebex based plugin for SSH. Should you still face problems, please open a support ticket here: [https://www.royalapplications.com/go/support-ticket-new](https://www.royalapplications.com/go/support-ticket-new)
Please include screenshots, maybe a short video which shows the process in PuTTY compared to rebex.

Stefan

If anyone is interested, I put in a Feature Enhancement Request for Royal Server Secure Gateway to support MFA…

> === Feature Enhancement Request === We’re trying out the Multifactor Authentication (MFA, a.k.a, two-factor or 2FA) feature on the Document Store on Royal Server. It works great! But that’s not quite what we needed. Can we do MFA on the Royal Server Secure Gateway? For instance, when the engineers arrive in the morning they would have to MFA to get their first connection through the Secure Gateway but after that, all new sessions would go through the Secure Gateway without re-checking the M…
