# Authentication Directory Lister does not include any form of authentication out of the box. This is intentional to keep the application focused and easier to maintain. However, there are ways to use external authentication with Directory Lister. The following are some known methods of adding authentication to your application. ## HTTP Basic Authentication Modern web servers have the ability to restrict access to a directory via a `.htpasswd` file. The way this is configured varies based on the web server in use so you will need to reference the documentation for your web server. ### Apache * [`mod_auth_basic` documentation](https://httpd.apache.org/docs/2.4/mod/mod_auth_basic.html) * [`.htpasswd` documentation](https://httpd.apache.org/docs/current/programs/htpasswd.html) ### NGINX * [Basic Authentication documentation](https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/) ## Authelia Proxy Authorization [Authelia](https://www.authelia.com/), the open-source authentication and authorization server, may be used to add authorization to an instance of Directory Lister behind a reverse proxy. * [Proxy Authorization documentation](https://www.authelia.com/reference/guides/proxy-authorization/) * [NGINX integration documentation](https://www.authelia.com/reference/guides/proxy-authorization/) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.directorylister.com/configuration/authentication.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
