From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why disable ssh login with root on a server if I only log in with keys, not password? (sh.itjust.works)

On a server I have a public key auth only for root account. Is there any point of logging in with a different account?

There must at least be MFA somewhere on the path then.

Even just keys, I wouldn't trust, unless they are stored on smartcards or some other physical "something I have", require a PIN/passphrase. and centrally managed so they can be revoked and rotated. Too many people use unprotected SSH keys.
