We're looking for guidance on a registration and authentication challenge.

Current Setup

• Contacts are managed in Salesforce and synced to Cvent as Campaign Members/Invitees.
• An integration provisions invited attendees into Okta.
• Cvent registration is protected behind Okta authentication, ensuring only invited attendees can access the registration site.
• Each attendee is currently associated with a single email address.

Challenge

Many of our invitees may attempt to register using an alternate email address rather than the email listed in Salesforce/Cvent.

We would like to support multiple valid email addresses for a single individual without:

• Creating duplicate attendee records in Cvent
• Breaking Salesforce ↔ Cvent integrations
• Impacting agenda syncs or downstream reporting
• Creating multiple registrations for the same person

Desired State

We're exploring whether Cvent can:

1. Keep the registration site fully protected behind authentication.
2. Allow Okta to authenticate a user using any approved email address associated with that person.
3. Permit registration once authenticated, even if the email used for login is not the exact email on the Cvent invitation list.
4. Maintain a single attendee record within Cvent for reporting, agenda management, and Salesforce synchronization.

Questions

• Has anyone implemented a similar solution where attendees can authenticate using multiple email addresses while maintaining a single Cvent attendee record?
• Are there Cvent settings, SSO configurations, identity matching options, or integration patterns that support this use case?
• What are the recommended best practices for handling alternate email addresses without introducing duplicate contacts or registration records?

Any guidance, examples, or architectural recommendations would be greatly appreciated! Thanks!
