SSH Google 2FA Problems

Hello!

First off, sorry if this is the wrong section, I couldn't find one super applicable to this question...BUT:

I'm working on setting up Google Authenticator 2FA for all SSH logins on my server, I started following a forum post here, but it seems like they've really simplified the process so I ended up following another, more generic CentOS post here. So far I've done the following:

Installed google-authenticator.


Setup the the app on my phone, and initiated google-authenticator.


Modified /etc/pam.d/sshd with the line:


Modified /etc/ssh/sshd_config to show:



Restarted the sshd service.

After that I completely exited ssh, and reconnected to it, trying both my root, and user account. Neither seems to have been impacted by anything I changed, at all. It simply has me login as normal. Does anyone have experience with this? Have you guys tried adding 2FA to your systems lately? Any help is much appreciated!
