After you have your background information, you can use the Okta Admin Console and the Application Integration Wizard (AIW) to create your SSO integration inside the Okta org associated with your developer account.
Note: Creating your SSO app integration doesn't automatically make it available in the OIN. After you have created and tested it, you need to (opens new window) submit your app integration to the OIN.
If you don't have an Okta developer account, begin by signing up for one at
https://developer.okta.com/signup/. (opens new window) After you request the developer account and have received the initialization email, click the link in the email to go to your developer org. Sign in as a user with administrative privileges. In the Admin Console, go to Applications > Applications. Click Create App Integration. Create an OIDC integration On the Create a new app integration page, select OpenID Connect in the Sign-in method section. Choose either Web Application or Single-Page Application as the Application type for your integration. The OIN only publishes cloud-based SaaS apps, either traditional Web applications with a back-end or a modern browser-based SPA. Click Next. In General Settings, enter a name for your integration and (optionally) upload a logo. Add your Sign-in redirect URIs and optional Sign-out redirect URIs. These URIs must be absolute URIs, and you can specify more than one. (opens new window) In Assignments, assign a group or leave the Everyone default. Be sure to verify that the users you want to have access are assigned to the group that you select. For instructions on how to assign the app integration to individual users and groups, see the Assign applications for people and groups topic in the Okta product documentation. (opens new window) Click Save.
