Have you forgotten the root password in Fedora? Or do you want to change the root user password in your Fedora system? No problem! This brief guide walks you through the steps to change or reset root password in Fedora operating systems.

Reset Root User Password in Fedora Step by Step

This guide has been officially tested on Fedora 37, 36 and 35 versions. The steps provided below are same for resetting root password in older Fedora versions and Fedora Silverblue edition.

Step 1 - Edit Boot Entry in Grub Menu

Switch on your Fedora system and press ESC key until you see the GRUB boot menu. Once the GRUB menu is appeared, choose the Kernel you want to boot and hit e to edit the selected boot entry.

Step 2 - Find ro Kernel Parameter

In the next screen, you will see all boot parameters. Find the parameter named ro.

Step 3 - Modify ro Kernel Parameter

Replace the 'ro' parameter with 'rw init=/sysroot/bin/sh'(without quotes, of course). Please mind the space between "rw" and "init=/sysroot...". After modifying it, the kernel parameter line should look like below.

After changing the parameters as shown above, press Ctrl+x to enter into the emergency mode i.e. single user mode. You will be again prompted to press the ENTER key for maintenance.

Step 4 - Mount Root File System in Read/Write Mode

From the emergency mode, enter the following command to mount root (/) file system in read/write mode.

chroot /sysroot/

Step 5 - Reset Forgotten Root Password in Fedora

Now change the root password with passwd command:

passwd root

Enter the root password twice.

For demonstration purpose, I have used a simple password. But I highly suggest you to use a strong password.

Step 6 - Enable SELinux Relabeling

After resetting the root password, run the following command to enable SELinux relabeling on reboot:

touch /.autorelabel

Heads Up: If you do not do SELinux relabeling, the boot process may fail. You may have to do a hard-reboot and start back at step 1.

Step 7 - Reboot Fedora

Finally, exit the single user mode and reboot the Fedora system to normal mode by running the following command:

exit
reboot

Wait for SELinux relabeling process to complete. It will take a few minutes depending upon the filesystem's size and speed of your hard drive.

If you only see the Plymouth boot screen, simply press ESC key to view the SELinux progress.

Step 8 - Login to Fedora

After the filesystem relabeling is completed, you can log in to your Fedora system with new root password.

Conclusion

As you can see, the steps to reset forgotten root password in Fedora 37 and older versions is fairly easy and exactly same as resetting root password in RHEL and its clones like CentOS, AlmaLinux and Rocky Linux.

Another way to change the root passwd or create one when Fedora gives you the option to create one on installation is to open a terminal and enter “sudo passwd root”. You will be asked to give your sudo password and then enter the new root password, and then enter it again. I have used this on several of the latest versions of Fedora, including 36.
