We have a web application. We also have a separate customer who already uses Okta to manage his employee's access to various applications. This client wants to use Okta SSO for login to our app.
We created a trial Okta account and integrated a "login with Okta" button based on documentation here for a Node/Angular App https://developer.okta.com/quickstart/#/angular/nodejs/generic
This method allows authentication for users who have an account in our Okta. However, this does not seem right as future customers would have users tied to their own accounts.
How do we solve this? Do we need to register with OIN and only then it is possible for other Okta accounts to enable SSO into our app?
