Benefits of using Logto Protected App

Instead of writing long lines of code, prioritize your core product.

Save time and effort in auth integration

Simplify integrations by separating authentication from your application. After the user is authenticated, the Protected App delivers content from your server.

Development freedom: choose what you love

Don't stress over missing SDKs or environments. Logto's Protected App doesn't need an SDK and drops in front of your app as a proxy.

Edge-network proxy infrastructure

No authentication servers to run. It runs on Cloudflare's edge network, which gives you automatic scaling and low-latency response times worldwide.

Authentication without the boilerplate

Start from scratch with no prerequisites and ship in a few minutes.

Protected app workflow

The Protected App handles session state and user information. If a user isn't authenticated, it redirects them to the sign-in page. After authentication, it securely includes user authentication details and forwards the request to the origin server.
