+## 10. How can I 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`:
+
+```
+this.auth.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.
+
+Additionally, if you are using our AuthGuard, you may want it to pick up the same connection when it would redirect for login. To do so, you should provide the `connection` property when configuring Auth0:
+
+```
+bootstrapApplication(AppComponent, {
+  providers: [
+    provideAuth0({ 
+      authorizationParams: { 
+        connection: 'connection_logical_identifier' 
+      }
+    }),
+  ]
+});
+```
