This article provides step by step instructions on how to reset lost or forgotten RHEL 8 Linux root administrative password. To recover the root password you will first boot to the GRUB menu and perform a break at early stage of the boot process. Afterwards, you will remount the sysroot directory with read & write access and change the root password on Redhat 8 by using the passwd command to set the new root password.
