Setting up a root password is a mandatory part of a Fedora installation. If you forget or otherwise lose your root password, there are procedures to reset it.
- If you have set a password for your boot loader, refer to this section.
- If you want to reset the boot loader password, refer to these instructions.
- If none of these scenarios apply to you, proceed to the next section.
Fedora uses run levels to determine the services being run when you start your system. Run level 1 can be used as a recovery mode. Booting Linux under run level 1, which is also called single user mode, will display a root prompt on bootup, from which you can reset the root password.
🔗 Entering Recovery Mode
While you system is starting up, hold down the Ctrl key or Esc to see the boot loader menu. After you see the menu:
- Use the arrows to select the boot entry you want to modify.
- Press e to edit the entry.
- Use the arrows to go to kernel line.
- Press a or e to append this entry.
- At the end of the line add the word single or the number 1.
- Press Enter to accept the changes.
- Press b to boot this kernel.
A series of text messages scrolls by and after a short time, a root prompt appears awaiting your commands (#).
🔗 Changing root password
As root, changing password does not ask for your old password. Run the command:
# passwd
Enter your new root password twice. Congratulations! You now have now reset your root password. You can type reboot and press enter to restart your system.
🔗 Reset Password When Boot Loader is Password Protected
- Boot from the install or rescue CD/DVD.
- Select "Rescue installed system."
- Answer the prompts for language and keyboard. Starting the network is optional and not needed.
- Let the rescue mode mount your file systems in the read/write mode.
- Hit Enter to get the shell prompt.
- At the prompt, enter the following commands. Do not enter any # mark or the text following it. These comments are shown for explanatory purposes only.
chroot /mnt/sysimage # Change to your disk file system passwd # Change the root password exit # Exit the chroot environment exit # Exit the rescue mode
The system now unmounts the file systems and reboots.
