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.

If you've lost root credentials you can always bypass them.

When your in after this point you can reset the password to something you know then continue from there.

Wait wtf? You can just reset root password that easy? What’s even the point of having a password, if all of your data and info is so easily accessed if someone gets physical hold of the machine. I guess so software/remote hackers can’t get your stuff, but still. This seems wild to me, I dunno.

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.

Edit: Thanks for all the comments below! I guess I’ve been spoiled by BitLocker in Windows being enabled by default and not having to think of disk encryption. Appreciate everyone’s time and responses!

Account passwords have never had the purpose of protecting data from physical access - on Linux or any other operating system that I’m aware of. Physical access means an attacker can pull your drive and plug it into their computer, and no operating system can do anything to block access in that scenario, because the os on disk is not running.

You need disk encryption to protect your data. The trade off is that if you forget the encryption password, your data is unrecoverable by you. But that’s what password managers are for (or just writing it down and putting it in a safe).
