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.

Your ssh private keys are safe, assuming nobody has physical access to your home directory. You can configure them to not require a password.
If someone has physical access to your computer then they could become compromised. If you are worried about that you could encrypt the whole drive.
Unless some sandboxing or other explicit security measure is in place, any software you run typically has access to your entire home directory, including
.ssh/. If any one of those was compromised somehow, they've got access to your SSH keys.That's a gigantic attack surface if you ask me.
It's not a solution.
Example: there's another user with sudo access, he has access to my home folder, encrypting the drive doesn't solve anything. Or maybe you just are not the system administrator.
It's not my usecase, but it's definitely a reasonable situation.
You can encrypt your /home separate with another password.
Anyone with sudo access can keylog your password
