docs: Okta SSO setup is self-service in the dashboard (#1027)

The Okta page told readers to email their Client ID, Client Secret and
domains to NetBird support. SSO is now set up in Integrations >
Single Sign-On > Connect Okta, where the wizard takes those values
directly and then asks for domain ownership verification if needed.

 ## Get Started with NetBird-Okta Integration
 
-To set up SSO, go to `Integrations` in the NetBird admin console's left menu to access the Identity Provider integration page. Click the `Connect Okta` button to get started with the Okta-NetBird integration. This will open a pop-up window with detailed instructions on synchronizing NetBird and Okta.
+To set up SSO, open `Integrations` in the NetBird admin console's left menu and select the `Single Sign-On` tab. On the Okta card, click `Connect Okta`.

 ## Configuring SSO in Okta
 
-The next step is to configure Okta-NetBird SSO integration.
+The next step is to collect Okta's OpenID Connect details and enter them in NetBird. SSO setup is self-service: you don't need to send these details to the NetBird team.
 
-In NetBird, click the `Continue →` button. A new wizard screen will appear, offering the instructions for retrieving Okta’s OpenID Connect credentials. You can click `Close` and navigate to Okta.
+In NetBird, click the `Continue →` button. The wizard shows the `Enter your Okta details` form. Keep it open and switch to Okta to collect the values.
 
 * Click on the `Sign On` tab on Okta. Look for `OpenID Connect` under `Sign on methods` in the `Settings` section.
 * Copy the `Client ID` value.
 * Copy the `Client Secret` value.
 
-Store these credentials securely, as you will need them soon.
+Treat the `Client Secret` like a password. Paste it straight into the NetBird wizard, and don't share it over email or chat.

-This completes the first stage, enabling Single Sign-On (SSO) from NetBird's login page using Okta credentials. Now, you can navigate to [app.netbird.io](app.netbird.io) and log in using [Okta Verify](https://help.okta.com/eu/en-us/content/topics/end-user/ov-overview.htm).
+Click `Connect`. If your primary email domain isn't verified yet, NetBird asks you to prove you own it. The `Verify Domain Ownership` dialog shows a TXT record to add to your DNS:
+
+* `Host`: your primary email domain, for example `mycompany.com`.
+* `Value`: `nb-verification=` followed by a token unique to your account. Copy it from the dialog.
+
+Sign in to your DNS provider, add the TXT record, then click `Start Verification`.
+
+DNS changes can take a while to apply. If NetBird doesn't find the record straight away, click `Verify Later` and try again once the record has propagated: on the `Single Sign-On` tab, click `Settings` on the Okta card, open the `Domains` tab, and click `Verify` next to the domain. If you can't edit DNS for the domain, you can verify it by emailing [support@netbird.io](mailto:support@netbird.io) from an address on that domain instead.
+
+When the domain shows `Ownership Verified`, the Okta card on the `Single Sign-On` tab shows `Active`.
+
+This completes the first stage, enabling Single Sign-On (SSO) from NetBird's login page using Okta credentials. Now, you can navigate to [app.netbird.io](https://app.netbird.io) and log in with your Okta account.
