When you deploy the vCenter Server Appliance, you set the initial password of the root user, which expires after 365 days by default. For security reasons, you can change the root password, as well as the password expiration settings.


Log in to the vCenter Server Appliance Management Interface as root.


  1. In the vCenter Server Appliance Management Interface, click Administration.
  2. In the Change root password pane, change the root password and click Submit.
  3. Configure the password expiration settings for the root user.
    1. In the Root password expires section, set the password expiration policy.




      The password of the root user expires after a particular number of days. You must provide the following information:

      • Root password validity (days)

        The number of days after which the password expires.

      • Email for expiration warning

        The email address to which the vCenter Server Appliance sends a warning message before the expiration date.


      The password of the root user never expires.

    2. In the Password expiry settings pane, click Submit to apply the new password expiry settings.

    In the Password expires on text box, you can see the new expiration date.
