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.

Hey guys. I'm new to Linux and I'm running Linux Mint 21.2 Cinnamon. Yesterday I have f*cked up. I was testing things in users and geve myself standart priveledges insted of Admin ones I had from beggining and then restarted PC. I then tried log back into users tab and change myself back to Admin but even tho the password is correct It says that it is not. /So at this point there is only one user in PC who has standart privliedges and no Admin./ I then tried to access root via terminal and this time It said that I don't have permision to do that. And this is where I'm at right now. Please help get back my admin privliedges.

Edit: Issue is fixed. I started GRUB and changed my password which fixed the whole issue. Once again big Thank you to everyone who gave me tips and also big thank you to the guy who started posting about rowing machines. You all wonderful.

New to Linux so I’m sorry if I’m being ignorant, but it does seem crazy you can get access to a machine without the password.

This is always the case, no matter what OS you use, unless you use full-disk encryption. User credentials are all just data on a disk, so if someone has physical access to your machine, and your disk isn't encrypted, then they can access (and change) those credentials or any other data.

What’s even the point of having a password

As you say, preventing remote access is one, but also a password will slow someone down a bit, and stop low-knowledge adversaries entirely, possibly. Also you will at least know someone has messed with your machine if they change the password.

Really, though, there's nothing malicious someone can do to an unencrypted computer by changing the password that they couldn't do without changing the password (copy all your files, delete all your files, install malicious software). Except I guess annoying you by making you change your password back. 😆
