+We aim to make the web frontend responsive to multiple screen resolutions. There are a few guidelines which we aim to

+- The available space is utilized efficiently in order to avoid scrolling where possible.
+- The user only has to scroll in one direction to view available information. This direction should always be

+## Security
+
+The following information covers some security topics some users may wish to be familiar with.
+
+#### Pushed Authorization Requests Endpoint
+
+The [Pushed Authorization Requests] endpoint is discussed in depth in [RFC9126] as well as in the
+[OAuth 2.0 Pushed Authorization Requests](https://oauth.net/2/pushed-authorization-requests/) documentation.
+
+Essentially it's a special endpoint that takes the same parameters as the [Authorization] endpoint (including
+[Proof Key Code Exchange](#proof-key-code-exchange)) with a few caveats:
+
+1. The same [Client Authentication] mechanism required by the [Token] endpoint **MUST** be used.
+2. The request **MUST** use the [HTTP POST method].
+3. The request **MUST** use the `application/x-www-form-urlencoded` content type (i.e. the parameters **MUST** be in the
+   body, not the URI).
+4. The request **MUST** occur over the back-channel.
+
+The response of this endpoint is a JSON Object with two key-value pairs:
+- `request_uri`
+- `expires_in`
+
+The `expires_in` indicates how long the `request_uri` is valid for. The `request_uri` is used as a parameter to the
+[Authorization] endpoint instead of the standard parameters (as the `request_uri` parameter).
+
+The advantages of this approach are as follows:
+
+1. [Pushed Authorization Requests] cannot be created or influenced by any party other than the Relying Party (client).
+2. Since you can force all [Authorization] requests to be initiated via [Pushed Authorization Requests] you drastically
+   improve the authorization flows resistance to phishing attacks (this can be done globally or on a per-client basis).
+3. Since the [Pushed Authorization Requests] endpoint requires all of the same [Client Authentication] mechanisms as the
+   [Token] endpoint:
+   1. Clients using the confidential [Client Type] can't have [Pushed Authorization Requests] generated by parties who do not
+      have the credentials.
+   2. Clients using the public [Client Type] and utilizing [Proof Key Code Exchange](#proof-key-code-exchange) never
+      transmit the verifier over any front-channel making even the `plain` challenge method relatively secure.
+
+#### Proof Key Code Exchange
+
+The [Proof Key Code Exchange] mechanism is discussed in depth in [RFC7636] as well as in the
+[OAuth 2.0 Proof Key Code Exchange](https://oauth.net/2/pkce/) documentation.
+
+Essentially a random opaque value is generated by the Relying Party and optionally (but recommended) passed through a
+SHA256 hash. The original value is saved by the Relying Party, and the hashed value is sent in the [Authorization]
+request in the `code_verifier` parameter with the `code_challenge_method` set to `S256` (or `plain` using a bad practice
+of not hashing the opaque value).
+
+When the Relying Party requests the token from the [Token] endpoint, they must include the `code_verifier` parameter
+again (in the body), but this time they send the value without it being hashed.
+
+The advantages of this approach are as follows:
+
+1. Provided the value was hashed it's certain that the Relying Party which generated the authorization request is the
+   same party as the one requesting the token or is permitted by the Relying Party to make this request.
+2. Even when using the public [Client Type] there is a form of authentication on the  [Token] endpoint.

+
+## Frequently Asked Questions
+
+### Why isn't my application able to retrieve the token even though I've consented?
+
+The most common cause for this issue is when the affected application can not make requests to the Token [Endpoint].
+This becomes obvious when the log level is set to `debug` or `trace` and a presence of requests to the Authorization
+[Endpoint] without errors but an absence of requests made to the Token [Endpoint].
+
+These requests can be identified by looking at the `path` field in the logs, or by messages prefixed with
+`Authorization Request` indicating a request to the Authorization [Endpoint] and `Access Request` indicating a request
+to the Token [Endpoint].
+
+All causes should be clearly logged by the client application, and all errors that do not match this scenario are
+clearly logged by Authelia. It's not possible for us to log requests that never occur however.
