To understand how this happens, imagine a native iOS app that wants to make API calls, but instead of doing it directly, communicates with a server owned by the same app and passes that server a token generated using the iOS SDK. Use the state parameter when using the login dialog. If you self-host your app or your hosting service doesn't offer HTTPS by default, you can obtain a free certificate for your domain s from Let's Encrypt.

The App Secret is used in some of the Login flows to generate access tokens and the Secret itself is intended to secure usage of your App to only those that are trusted.

If you don't use the Facebook SDKs in your app, it is extremely important that you manually implement frequent checks of the token validity — at least daily — to ensure that your app is not relying on a token that has expired early for security reasons. The code-generated short-term access tokens flow requires the app server to exchange the code for a token, which is more secure than obtaining a token in the browser. In some configurations, apps will reuse a long-term token across multiple clients.

Enable Strict Mode Strict Mode keeps apps safe by preventing bad actors from hijacking your redirect. Thanks all developers for comments.

Some desktop and mobile native apps authenticate users by doing the OAuth client flow inside an embedded webview.
For native apps, we suggest that the app communicates with your own server and the server then makes the API requests to Facebook using the App Access Token.

If you don't use the Facebook SDKs, regularly check whether the access token is valid. Web OAuth Login settings enables any OAuth client token flows that use the Facebook web login dialog to return tokens to your own website. When you start the reset process, you can specify a number of hours that the compromised secret will continue to work for when making requests, however anything sent from Facebook such as signed requests will use the new secret straight away, so you must adjust your code to expect it as soon as possible.

The secret can be used to easily create an App Access Token which can make API requests on behalf of any user of the app, which makes it extremely important that an App Secret is not compromised. To understand how this happens, imagine a native iOS app that wants to make API calls, but instead of doing it directly, communicates with a server owned by the same app and passes that server a token generated using the iOS SDK.
