Blocking domains from registration

[dan]

How to restrict registration by email domain ?

I seen "Blocked domains" in the Tenant Security settings but I would like to deny all domains except some client domains?

from https://github.com/FusionAuth/fusionauth-issues/issues/31

the built-in domain blocking is documented here: https://fusionauth.io/docs/v1/tech/advanced-threat-detection/#registration-domain-blocking

However:

• It only blocks specific domains so you can't block 'all domains except '
• It requires an enterprise license

As an alternative, consider a registration transactional webhook which could examine the domain provided by a user and fail if it didn't match a list of your domains: https://fusionauth.io/docs/v1/tech/events-webhooks/events/user-registration-create
