Configuring SSO authentication in Okta
After logging into the Okta panel, you will be redirected to the dashboard. From here, we will configure Okta to enable Single Sign-On (SSO) authentication for our application.
Assigning users to group
We need to add groups and add the required users to the appropriate group.
!Note: Only users who are members of this group will be able to sign in to your application.
In the side menu, navigate to the Groups page
then click to the Add group button
A modal window will appear with the configuration form.
Fill this form with the group name and description, then click the Save button.
In the side menu, navigate to the People page, then choose a particular person in the list and click to navigate to the Person page
Click on the Groups subtitle to navigate to the profile page
Click on the Search field and enter the group name that you want to assign the user with, then click to the appearing group.
Creating an application
An application refers to a cloud or on-premises service integrated with Okta for single sign-on, enabling users to securely access and authenticate across multiple applications with a single set of credentials.
Next, navigate to the Applications page (as shown in the screenshot)
Click on the Create App Integration button
A modal window will appear with configuration options. Select the options as shown in the screenshot, then click the Next button.
You will be redirected to the configuration page:
Follow the instructions below and configure the settings as marked in the next two screenshots:
- I will set my app name to "SSO OIDC", but you can use just "your application".
-
Sign-in redirect URIs: The format should be:
https://<your-user-pool-domain>/oauth2/idpresponsewhere<your-user-pool-domain>is your Cognito User Pool Domain
(example: https://eu-north-2uasd2wr7mv.auth.eu-north-1.amazoncognito.com/oauth2/idpresponse).
-
Sign-out redirect URIs: This ensures users are properly signed out when logging out of our application.
Input:
https://yourapp.com/ - Right holder access: choose the Limit access to selected groups option and enter group names you want to give access to your application application.
- Click on the Save button.
You will then be redirected to the newly created application's page.
Configuring a User Okta profile (Add Roles to Profile)

Then, click the Create rule button.
Only users who are members of the selected group (and assigned the app) will be able to sign in.
Configuring a new Event Hooks
Event Hooks in Okta SSO allow your application to track IAM related events.
We will create an event hook that listens for two specific events:
- User removed from group
- User deleted
These events will trigger a soft delete of the corresponding user in your application.
In the side menu, navigate to the Event hooks page:

Click on the Edit button to enable editing attributes of the profile. Slide down to the bottom of the page.
Now, you can choose any number of roles from the list for the particular user. Click the Save button.
Deleting users
Delete user from group:
To trigger a soft-delete of a user in your application, you need to either remove the user from an Okta group or fully delete the user from Okta IAM.
To soft-delete a user from all rights holders where the user was, you need to remove the user from the corresponding Okta group (the group with the Group name defined in your SSO Client Provider).
In the side menu, navigate to the Groups page and click on the group which you want to remove users:
Next to the user you want to remove, click on the cross (x) icon and the user will be removed.
Once the user is removed from the group, they will be soft-deleted in your application.
Note: Users will be removed only when deleted from groups that are present in your app SSO Providers Group name, if not this event hook will be skipped.
Delete user from IAM:
In the side menu, navigate to the People page and select the the user which you want to delete:
You will be redirected to the User Profile page. Click on the More Actions button, then click Deactivate to deactivate the user.
A modal window will appear with. Click Deactivate.
Then after the user deactivated, the Delete button will appear. Click Delete to completely delete the user from IAM.
A modal window will appear with. Click Delete.
After this, the selected user will be completely deleted from Okta IAM.
If a user with the same email exists in your application, that user will also be soft-deleted in your application.

Okta Multi-Factor Authentication (MFA) is now successfully configured.
How to connect to your application
To enable Okta login for your users in your application, you need to retrieve the following three parameters:
- Client ID
- Client Secret
- Okta domain
You can find this data on our Application details page. In the side menu (Okta panel), navigate to the Applications
Choose an application which you created previously. In my case, it is an SSO OIDC (marked below)
Instructions for copying the whole information that we should fill in your application can see below
Copy a issuer URL
To obtain the Issuer URL for your application, open: https://{yourOktaDomain}/.well-known/openid-configuration (In my case it is: https://integrator-1609932.okta.com/.well-known/openid-configuration)
Then copy the value of the issuer field from the returned JSON:
β Now, you have all the required credentials to connect to your application!
