vCenter Single Sign-On administrator users can change expired passwords for System-Domain users. Request that an administrator resets your password.
If you are a vCenter Single Sign-On administrator user, use the ssopass command-line tool to reset the password.

Open an elevated command prompt and run the command:
SET JAVA_HOME=C:\Program Files\VMware\Infrastructure\jre
Note: This is the default path of the JRE folder for vCenter Server 5.1. If vCenter Server has been installed in a custom location, change command accordingly.
