Church Account is the primary user account (user name and password) for accessing online Church resources. Church Account was formerly known as LDS Account. This forum is a space to discuss all things related to Church Accounts (registration, account recovery, user experience, vulnerabilities, etc.).
I recommend you reach out to whomever is over Seminary in your ward or stake. Unless someone on this user-to-user mutual help forum has experience that can chime in, you may not receive anything timely enough to be useful.
