+## Skip the Auth0 login page?
+
+When integrating with third party providers such as Google or Microsoft, being redirected to Auth0 before being redirected to the corresponding provider can be sub-optimal in terms of user-experience.
+If you only have a single connection enabled, or you know up front how the user wants to authenticate, you can set the `connection` parameter when calling `loginWithRedirect()` or `loginWithPopup()`:
+
+```
+loginWithRedirect({
+  // ...
+  authorizationParams: {
+    connection: 'connection_logical_identifier'
+  }
+})
+```
+
+Doing so for connections such as Google or Microsoft, would automatically redirect you to them instead of showing the Auth0 login page first.
+
+ℹ️ You can find the connection's logical identifier as the **connection name** in the connection settings in the Auth0 dashboard for your tenant.
