Boot into "single user mode". Append single at the end of grub command line. Hit e at grub boot screen to edit it. Then at the root prompt type passwd to change your password.

Using grub:

  1. select the appropriate boot entry, then press 'e'
  2. look for the line that starts with "linux" or "linux16" (for uefi: "linuxefi")
  3. place the cursor at the end of that line, append "<space>rw<space>init=/bin/bash" (without quotes)
  4. hit Ctrl-x and the system will boot with root to bash
  5. enter "passwd", enter new password (twice)
  6. to make selinux happy: enter "touch /.autorelabel"
  7. reboot: "/sbin/reboot -f"

Remember: with great power comes great responsibility.

This is the correct method to recover a lost root password with systemd. This assumes that grub is not locked.

what do you mean with ".. grub is not locked" ?
