Two factor authentication for FTP

We are moving to two factor authentication for our ftp accounts, using Duo Security. It does not appear that there is any way to accommodate that with Directory Opus. Is there, or will there be?

BTW, I saw a mention from 2018 that it was not available. Given the current movement to 2FA/MFA it seems like this is something that should now be in Directory Opus.

Do you have more detail on that? Is it for FTP or SFTP or FTPS?

We are using SFTP (FTP over SSH)
