Reset VMware vCenter Appliance 6 root password

by Roger Lund

If your like me, you often forget passwords or domains you setup in your lab environments.

Here are a blog post I found useful when playing in my lab.


VMware vCenter Server Appliance 5.5 root account locked out after password expiration (2069041)

VMware vCenter Server Appliance

Product Version(s):
VMware vCenter Server Appliance 5.5.x



“To reactivate the root account:

  1. Reboot the vCenter Server appliance using the vSphere Client.
  2. When the GRUB bootloader appears, press the spacebar to disable autoboot.Note: If the time between when you power on the virtual machine and when it exits the BIOS or EFI and launches the guest operating system is too short, you can adjust the delay. For more information, see Delay the Boot Sequence in the VMware vSphere 5.5 Documentation guide.
  3. Type p to access the appliance boot options.
  4. Enter the GRUB password.



Now I locked my self out trying passwords. Thus when you hit p you have to type your password. But it doesn’t lock you out at this point. Thus I found my password after a bit of work.
