Is there a way to block users from accessing the portal (alumdb.okta.com). REASON: I am using OKTA only for Identity Management (using OpenID Connect). After they have been logged on to my External App, I don't want them to have access to alumdb.okta.com.
Is that possible in your environment? If so how do I implement that.
Perhaps Okta's Self-Service Registration feature would be a better fit for your solution. Leveraging the Okta Sign-In Widget, you can customize the Okta sign-in experience allowing users to self-register into your custom app. In addition, post-registration workflows can be triggered that redirect users to your custom app or OIDC or SAML portal.
