+
+Enabling OAuth with [Vercel](https://vercel.com/docs/sign-in-with-vercel) allows your users to sign up and sign in to your Clerk app with their Vercel account.
+
+## Configure for your development instance
+
+For _development instances_, Clerk uses preconfigured shared OAuth credentials and redirect URIs—no other configuration is needed.
+
+1. In the Clerk Dashboard, navigate to the [**SSO connections**](https://dashboard.clerk.com/~/user-authentication/sso-connections) page.
+1. Select **Add connection** and select **For all users**.
+1. In the **Choose provider** dropdown, select **Vercel**.
+1. Select **Add connection**.
+
+## Configure for your production instance
+
+For _production instances_, you must provide custom credentials.
+
+To make the setup process easier, it's recommended to keep two browser tabs open: one for the [Clerk Dashboard](https://dashboard.clerk.com/~/user-authentication/sso-connections) and one for your [Vercel team settings](https://vercel.com/account).
+
+<Steps>
+  ### Enable Vercel as a social connection in Clerk

+  1. Select **Add connection** and choose **For all users**.
+  1. In the **Choose provider** dropdown, select **Vercel**.
+  1. Ensure that both **Enable for sign-up and sign-in** and **Use custom credentials** are toggled on.
+  1. Save the **Authorization Callback URL** somewhere secure. Keep the modal and page open.

+
+  1. In your Vercel dashboard, navigate to your team's **Settings** tab.

+  1. Optionally, upload a logo for your app.

+  1. Scroll to **Authorization Callback URLs** and add the **Authorization Callback URL** you saved from the Clerk Dashboard.
