+For `redirect_url`, this should be used to bring the user to where they were while initiating the login process (now with the login complete).
+This should be used in a way that is compatible with a different device being used to authorize the sign in than the one being logged in on.
+An example for this is checking if the sign in was attempted from this device with a cookie, if so, redirect the user to where wanted to log in,
+otherwise show a "continue on device" message.
+
+The `redirect_url` SHOULD be shown to the user and in a way that indicates it will take the user back to the app, such as `Return to website`.

 HTTPS should always be used except for `.onion` services, which should be contacted using HTTP.
 
 Clients MAY or MAY NOT decide to implement support for `.onion` services.
