Recover root password in Linux

Recover root password


If you forgot your root password on Linux, recovering root password can be done
by booting Linux under a specific mode: single user mode.

This tutorial will show how to boot Linux in single user mode when using GRUB
and finally how to change root password.

Entering single user mode:

In GRUB select kernel you want to boot and hit 'e' to edit the line.
Select the kernel line and hit 'e' again to edit thet line.
Now add '1' or write 'single' to the end of line, and press enter
and then press 'b' to boot system.

This will make you the "root" user without asking for a password. Once the
system has booted, you can change the root password using the password
command.

Command to change password: passwd
