Reset VCenter SSO ADMINISTRATOR Credentials

 

By default, the vCenter Single Sign-On password will be expires in every 90 days. To prevent the unexpected expiration, the vSphere Client issues a warning when the password is about to expire; however, if you are struck in this  situation where you cannot recall the password or the password has expired, it can be reset. The reset process is performed from an SSH session to vCenter.
