eWebinar's basic access control (included in every plan) lets you block specific people from registering by listing their email addresses. The Advanced access control add-on adds a much richer set of gates on top: email-address quality checks, domain allow/block lists, SSO login, and session-capacity limits.
Where to configure it
Once the add-on is enabled on your account, open a webinar in edit mode and go to the Registration tab → Access control section. Access control is configured per webinar, not globally.
Pick a mode
The first decision is whether you want to block certain registrants or only allow certain registrants. Each mode exposes a different set of rules.
Block certain registrants
- Require work emails: rejects common free/personal email domains (Gmail, Outlook, etc.) at the point of registration.
- Don't allow temporary emails: detects and blocks disposable email addresses (DEAs). eWebinar already validates deliverability; this adds a second layer.
- Block groups by email domain: block every registration using domains you specify (for example, a competitor's domain).
Only allow certain registrants
- Only allow certain individuals: whitelist individual email addresses.
- Only allow groups by email domain: whitelist entire domains (for example, your customer's company).
- Require SSO. Make people sign in with your company's single sign-on before they can register. Requires the SSO integration to be set up first (your IT team will need to be involved).
Common to both modes
- Limit number of registrants per session: cap how many people can register for a single session. Once the cap is reached, new registrations go to a different session.
