Oh ok ,
So according to this previous post, you have 2 options.
1 - Reinstall the SSO component
2- try to reset your Password with a query.
if SSO password ( admini@system-domain ) needs to be reset, please execute below query on RSA database:
UPDATE
[dbo].[IMS_PRINCIPAL]
SET
[PASSWORD] = '{SSHA256}KGOnPYya2qwhF9w4xK157EZZ/RqIxParohltZWU7h2T/VGjNRA=='
WHERE
LOGINUID = 'admin'
AND
PRINCIPAL_IS_DESCRIPTION = 'Admin';
This will reset the password to "VMware1234!", after which you login and change the password as needed.
Note: Take backup of RSA database before executing this
