To customize an Experience Cloud site:
  • Be a member of the site AND Create and Set Up Experiences

    OR

  • Be a member of the site AND View Setup and Configuration AND an experience admin, publisher, or builder in that site
To publish an Experience Cloud site:

Before you get started, create an Apex class that implements the Auth.CustomOneTimePasswordDeliveryHandler interface.

To add a custom OTP delivery handler to an Experience Cloud site, you must contact Salesforce Customer Support. When Support gives you access to this feature, we recommend that you configure all Experience Cloud sites in your org to use a custom OTP provider. If you don't configure a custom OTP provider, though, the site uses the Salesforce default provider.

  1. Contact Salesforce Customer Support and ask to allow a custom messaging service for OTPs sent to external users.
  2. From Setup, in the Quick Find box, enter Sites, and then select All Sites.
  3. Next to your Experience Cloud site name, click Workspaces.
  4. Select Administration, and then select Login & Registration.
  5. Under Custom One-Time Password (OTP) Delivery, for OTP Delivery Handler, click lookup magnifying glass and search for the custom OTP delivery Apex class that you created.
  6. Save your changes.
  7. Test all configurations for your site that send an OTP via SMS. When you confirm that all use cases are working as expected, implement your changes in production.
