 1. From the Segment web app, click **Catalog**.
 2. Search for "Zendesk" in the Catalog, select it, and choose which of your sources to connect the destination to.
-3. There are two ways to authenticate your Zendesk account with Segment:
-   * Use the standard email and password you use to Sign In to your Zendesk account. In the Zendesk settings, add your email in the **Email** setting and your password in the **Password** setting.
-   * Use Zendesk OAuth with a unique token. Get the corresponding token from your Zendesk account: **Settings > Channels > API** and under the Settings Tab choose the corresponding token from the "Active API Tokens" list. In the Zendesk settings, add your `email/token` in the **Email** setting (for example, `[email protected]/token` - use the actual word token in your email address) and add the actual token in the **Password** setting.
-4. Add your Zendesk subdomain in the **Subdomain** setting (not including `.zendesk.com`).
+3. Enter your Zendesk domain (not including `.zendesk.com`) and click **Connect**. The Zendesk OAuth login opens in a new tab. Sign in with your Zendesk credentials to authenticate and allow the Segment integration.
