Just saw this https://www.howtoforge.com/tutorial/secure-ssh-with-google-authenticator-on-centos-7/

 

and was wondering if its possible considering unRaid only lives on memory

There must already be a docker.

Not gonna work.

unRAID is based on Slackware, whichdoes not support PAM, which makes including stuff like TFA much harder to insert.

See here: https://registry.hub.docker.com/u/disconn3ct/docker-sshd-otp/

Seriously? SSHing into a docker container? that had always been a point of contention in docker. I suppose if you want to limit access to files or restrict access to the underlying OS, yes. I suppose careful consideration of the volume mounts and availability of the CLI tools and utilities could make it work, plus running the container in host mode. but you'd need to either shutdown the builtin SSH or use this in an alternate port.
