Thank you for reaching out to Okta community. The documentation shown for the Okta social login should be able to assist you with this. Take a look here: https://developer.okta.com/authentication-guide/social-login/ I recommend opening a Customer Support ticket if you have further questions. Best regards,
I have seen the guide, but no, it didn't answer my question. Simple Yes/No would suffice. Anyway, the service is missing a lot of features in the management area and being able to preview the login form based on your current settings is just one of them.
