Reset vCenter SSO Administrator Password vSphere 6.5
By default, the vCenter Single Sign-On password expires every 90 days. To prevent unexpected expiration, the vSphere Client issues a warning when the password is about to expire; however, if you find yourself in a 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.

Next, enable BASH shell access and launch BASH.
