If you've made the switch to AlmaLinux, you should enable 2FA for SSH authentication for more secure logins. Learn how to enable SSH 2FA on AlmaLinux in this tutorial.

AlmaLinux is a drop-in replacement for CentOS that also happens to be a 1:1 binary replacement for Red Hat Enterprise Linux. Chances are pretty good you'll be deploying this enterprise-ready Linux server distribution soon. When you do, you want to make sure it's as secure as possible.

One way to beef up the security of any Linux server is to enable two-factor authentication (2FA) for SSH logins. This setup is quite easy and makes remote connections considerably more secure. Instead of simply typing a password or key passphrase for SSH authentication, you'll also have to enter a six-digit 2FA code from your favorite authentication app (such as Authy or Google Authenticator).
