vmo6m (vmo6m) asked a question.
We would like to use okta signin widget for user registration (customer identity) and I have self-service registration configured for the associated SPA. However, we'd like a limited set of users able to register based on a regex of the email address or other custom authentication rules (e.g. a whitelist of valid emails). What's the best way to do this?

Cosmin here from Okta Support Team.
You can assign the self service registration option to a specific group, that way only users from that group can use this functionality. I am attaching here the documentation for that:

You can also refer to this documentation from our dev website: https://developer.okta.com/docs/guides/set-up-self-service-registration/customize-link-in-widget/#configure-registration-in-a-custom-sign-in-page-in-the-okta-hosted-widget
Please keep in mind that if you require further assistance you can open a case with our Dev team to get more information about this.
