Has the installation of Google Authenticator chaged for CentOS 7?

To help with ssh security on my centos7 server, I am trying to install google authenticator. Problem is, the guides I have found all say to do as a first step:

sudo yum install google-authenticator

However, I get a message that google-authenticator isn't available.

Do I need to point this to a certain repo? If so, how do I do that? (I'm a bit new to doing sysadmin-style work on CentOS7.

When doing some research, I found this out: https://www.howtoforge.com/tutorial/secure-ssh-with-google-authenticator-on-centos-7/

If you scroll down to the Idea, user mutwakel yassen mentioned "wgetting" the tar ball from the code itself, but looking at the link they provided, it points to the open source version of the Google app, which from my understanding, might be out of sync from the official Google version, which makes me conceed if it will work with my phone app.

Does anyone know if the official packages are in the repo, or if there is a way to install the Google version in other means? Or has anyone gotten the most recent version of Google Authenticator (at the time of writing, 4.44) to work with the open source project?
