+Before we dive into the details, here's a quick overview of the end-user experience. The sign-in process can be simplified as follows:
+
+```mermaid
+graph LR
+    A(Your app) -->|1. Invoke sign-in| B(Logto)
+    B -->|2. Finish sign-in| A
+```
+
+1. Your app invokes the sign-in method.
+2. The user is redirected to the Logto sign-in page. For native apps, the system browser is opened.
+3. The user signs in and is redirected back to your app (configured as the redirect URI).
+
+Regarding redirect-based sign-in:
+
+1. This authentication process follows the [OpenID Connect (OIDC)](https://openid.net/specs/openid-connect-core-1_0.html) protocol, and Logto enforces strict security measures to protect user sign-in.
+2. If you have multiple apps, you can use the same identity provider (Logto). Once the user signs in to one app, Logto will automatically complete the sign-in process when the user accesses another app.
+
+To learn more about the rationale and benefits of redirect-based sign-in, see [Logto sign-in experience explained](https://docs.logto.io/docs/tutorials/get-started/sign-in-experience).
