Unlock and Reset Vcenter root Password

1. Unlock the root Account:

  • Open a web browser and navigate to the VAMI interface of your vCenter Server Appliance. The URL is usually https://<vCenter_IP>:5480.
  • Log in with your root credentials.
  • Go to the “Access” tab and click on “Edit” next to “User Accounts.”
  • Select the “root” account and click on “Unlock Account.”

2. Reset the root Password:

  • In the same “User Accounts” section of the “Access” tab, click on “Edit.”
  • Select the “root” account and enter a new password in the “New Password” and “Confirm Password” fields.
  • Click on “Save Settings” to apply the new password.

3. Verify the Changes:

  • Log out of the VAMI interface and log back in with the new root password to ensure it’s working correctly.
  • You can also log in to the vSphere Client using the root account to verify access.

4. (Optional) Reset Password Using vSphere Client:

  • If you have access to the vSphere Client and vCenter Server is connected, you can reset the root password from the vSphere Client.
  • Log in to the vSphere Client with administrator credentials.
  • Navigate to the vCenter Server in the inventory.
  • Go to the “Configure” tab and select “Settings” under “Access.”
  • Click on “Edit” next to “Authentication” and then “Edit” next to “Password.”
  • Enter the new root password and click “OK” to save the changes.

5. Restart vCenter Services (if needed):

  • If you encounter any issues after changing the root password, you may need to restart the vCenter services.
  • You can do this from the VAMI interface by going to the “Services” tab and clicking on “Restart.”

After completing these steps, the root password for your vCenter Server should be successfully reset, and you should be able to log in with the new password.
