Hi Liu, 

We need more context. Are you trying to recover the password to the vCSA (root) or is the GRUB menu locked and you can't get in to change it? It shouldn't be changed from what it was previously.

Good day, Redhatcc,

The version is 6.7.  From the guide reset the password could be done frrom sso log in menu.

I saw root right menu all greyed. VAMI also has not root change password option.

In this case, I shall do changing password from ssh by putty or from GRUM menu?

Try changing it on boot. This method works all the way up to 7.0.3 but I have not tested on 8.x

1. Take a snapshot or backup of the vCenter Server Appliance before proceeding.

                       Caution: Do not skip this step

Note: If the vCenter Appliance is on the same ESXi hosts it manages, connect directly to the ESXi host that it is located on to perform these steps. If not, I would highly recommend moving the vCenter to a host you can login too, and open a console on to run these commands. 

2. Reboot the vCenter Server Appliance.
3. After the VCSA Photon OS starts, press the e key to enter the GNU GRUB Edit Menu.
4. Locate the line that begins with the word Linux.
5. Append these entries to the end of the line:
   
   rw init=/bin/bash
   
   The line should look like the following screenshot:
   
   
    
6. Press F10 to continue booting.
7. Run the command  

                  mount -o remount,rw / 

8. Unlock the 'root' account using below command if it is already locked due to multiple logins with incorrect password

                  pam_tally2 --user=root --reset

9. In the Command prompt, enter the command passwd and provide a new root password (twice for confirmation):

           passwd

 

10. Unmount the filesystem by running this command (yes, the unmount command is umount  -  it's not a spelling error):

           umount /

 

11. Reboot the vCenter Server Appliance by running this command:

           reboot -f

 

Please reply and let us know if that worked. Don't skip a step!
