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?

Then you can’t gain root privileges on your server. Are you really arguing for less security because it’s inconvenient?

This is end-user behavior and it’s honestly embarrassing. You should realize your security posture is much more important than “I left my phone on the other room”

This thread is embarrassing,
The person you're responding to could wipe your ass with a cli.

ffs...am I dealing with children here?
You've accessed your server as a user, and then you su - to root.
You don't need a phone or a yubi or a dreamcatcher, or a unicorn.
Please stop with your pretension.
You're so far out of your league that it's embarrassing to me that I've bothered to answer.

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.
