-# Duo Push Notification
-
-Using mobile push notifications is becoming the new trendy way to validate
-the second factor of a 2FA authentication process. [Duo](https://duo.com/)
-is offering an API to integrate this kind validation and **Authelia** leverages
-this mechanism so that you can simply push a button on your smartphone to be
-securely granted access to your services.
-
-<p align="center">
-  <img src="../../docs/images/2FA-PUSH.png" width="400">
-</p>
-
-In order to use this feature, you should first create a free account on Duo
-(up to 10 users), create a user account and attach it a mobile device. The name
-of the user must match the name of the user in your internal database (LDAP).
-In Duo interface, click on *Applications* and *Protect an Application*. Then
-select the option called *Partner Auth API*. This will generate an integration key,
-a secret key and a hostname. You can set the name of the application to
-**Authelia** and then you must add the generated information to your configuration
-as:
-
-    duo_api:
-      hostname: api-123456789.example.com
-      integration_key: ABCDEF
-      secret_key: 1234567890abcdefghifjkl
-
-This can be seen in [config.template.yml](../../config.template.yml) file.
-
-When selecting *Push Notification* at the second factor stage, you will
-automatically receive a push notification on your phone to grant or deny access.

-
-## Limitations
-
-Users must be enrolled via the Duo Admin panel, they cannot enroll a device from
-**Authelia** yet.
-
-
-## FAQ
-
-### Why don't I have access to the *Push Notification* option?
-
-It's likely that you have not configured **Authelia** correctly. Please read this
-documentation again and be sure you had a look at [config.template.yml](../../config.template.yml).

-# Security Keys (U2F)
-
-**Authelia** offers authentication using Security Keys like [Yubikey](Yubikey)
-which are one of the most secure way to authenticate and get authorized.
-It is already available for Google, Facebook, Github accounts and more.
-
-The protocol requires your security key to enrolled before authenticating.
-
-To do so, select the *Security Key* method at the second factor stage and
-click on the link *Not registered yet?*. This will send a link to your 
-user email address. This e-mail will likely be sent to
-https://mail.example.com:8080/ if you're testing Authelia and you've not
-configured anything.
-
-Confirm your identity by clicking on **Register** and you'll be asked to
-touch the token of your security key to enroll.
-
-<p align="center">
-  <img src="../../docs/images/REGISTER-U2F.png" width="400">

-
-Upon successful registration, you can authenticate using your security key
-by simply touching the token again when required:

-Easy, right?!
-
-## FAQ
-
-### Why don't I have access to the *Security Key* option?
-
-U2F protocol is a new protocol that is only supported by recent browsers
-and might even be enabled on some of them. Please be sure your browser
-supports U2F and that the feature is enabled to make the option
-available in **Authelia**.

-# Configuration
-
-Authelia is highly configurable thanks to a configuration file. 
-There is a documented template configuration, called
-[config.template.yml](../config.template.yml), at the root of the
-repository. All the details are documented there.
-
-When running **Authelia**, you can specify your configuration file by passing
-the file path as the first argument of **Authelia**.
-
-    $ authelia --config config.custom.yml
-
-
-## Secrets
-
-Configuration of Authelia requires some secrets or passwords. Please
-note that the recommended way to set secrets in Authelia is to use
-environment variables.
-
-A secret in Authelia configuration could be set by providing the
-environment variable prefixed by AUTHELIA_ and with name equals to
-the capitalized path of the configuration key and with dots replaced
-by underscores.
-
-For instance the LDAP password is identified by the path
-**authentication_backend.ldap.password**, so this password could
-alternatively be set using the environment variable called
-**AUTHELIA_AUTHENTICATION_BACKEND_LDAP_PASSWORD**.
-
-If for some reason you prefer keeping the secrets in the configuration
-file, be sure to apply the right permissions to the file in order to
-prevent secret leaks if an another application gets compromised on your
-server. The UNIX permissions should probably be something like 600.

+## Access Control List
+
+With **Authelia** you can define a list of rules that are going to be evaluated in
+order when authorization is delegated to Authelia.
+
+The first matching rule of the list defines the policy applied to the resource and, if
+no rule matches the resource, a customizable default policy is applied.
+
+
+## Access Control Rule
+
+A rule defines two things:
+
+* the matching criterion of the request presented to the reverse proxy
+* the policy applied when all criterion match.
+
+The criterion are:
+
+* domain: domain targeted by the request.
+* resources: list of patterns that the path should match (one is sufficient).
+* subject: the user or group of users to define the policy for.
+* networks: the network range from where should comes the request.
+
+A rule is matched when all criterion of the rule match

+A policy represents the level of authentication the user needs to pass before
+being authorized to request the resource.
+
+There exist 4 policies:
+
+* bypass: the resource is public as the user does not need any authentication to
+get access to it.
+* one_factor: the user needs to pass at least the first factor to get access to
+the resource.
+* two_factor: the user needs to pass two factors to get access to the resource.
+* deny: the user does not have access to the resource.
+
+## Domains
+
+The domains defined in rules must obviously be either a subdomain of the domain
+protected by Authelia or the protected domain itself. In order to match multiple
+subdomains, the wildcard matcher character `*.` can be used as prefix of the domain.
+For instance, to define a rule for all subdomains of *example.com*, one would use
+`*.example.com` in the rule.
+
+## Resources
+
+A rule can define multiple regular expressions for matching the path of the resource. If
+any one of them matches, the resource criteria of the rule matches.
+
+
+## Subjects
+
+A subject is a representation of a user or a group of user for who the rule should apply.
+
+For a user with unique identifier `john`, the subject should be `user:john` and for a group
+uniquely identified by `developers`, the subject should be `group:developers`. Unlike resources
+there can be only one subject per rule. However, if multiple users or group must be matched by
+a rule, one can just duplicate the rule as many times as there are subjects.
+
+*Note: Any PR to make it a list instead of a single item is welcome.*
+
+## Networks
+
+A list of network ranges can be specified in a rule in order to apply different policies when
+requests come from different networks.
+
+The main use case is when, let say a resource should be exposed both on the Internet and from an
+authenticated VPN for instance. Passing a second factor a first time to get access to the VPN and
+a second time to get access to the application  can sometimes be cumbersome if the endpoint is not
+that much sensitive.
+
+Even if Authelia provides that flexbility, you might prefer higher level of security and avoid
+this option entirely. You and only you can define your security policy and it's up to you to
+configure Authelia accordingly.
+
+
+## Complete example
+
+Here is a complete example of complex access control list that can be defined in Authelia.
+
+    access_control:
+        default_policy: deny
+
+        rules:
+        - domain: public.example.com
+          policy: bypass
+
+        - domain: secure.example.com
+          policy: one_factor
+          networks:
+          - 192.168.1.0/24
+      
+        - domain: secure.example.com
+          policy: two_factor
+
+        - domain: singlefactor.example.com
+          policy: one_factor
+
+        - domain: "mx2.mail.example.com"
+          subject: "group:admins"
+          policy: deny
+        
+        - domain: "*.example.com"

+This file should be set with read/write permissions as it could be updated by users
+resetting their passwords.
+
+## Passwords
+
+The file contains hash of passwords instead of plain text passwords for security reasons.
+
+You can use authelia binary or docker image to generate the hash of any password.
+
+For instance, with the docker image, just run
+
+    $ docker run authelia/authelia:latest authelia hash-password yourpassword
+    $6$rounds=50000$BpLnfgDsc2WD8F2q$be7OyobnQ8K09dyDiGjY.cULh4yDePMh6CUMpLwF4WHTJmLcPE2ijM2ZsqZL.hVAANojEfDu3sU9u9uD7AeBJ/
+
+
+## Password Hash Function
+
+The only supported hash function is salted sha512 determined by the prefix `$6$` as described
+in this [wiki](https://en.wikipedia.org/wiki/Crypt_(C)) page. 
+
+Although not the best hash function, Salted SHA512 is a decent algorithm given the number of rounds is big
+enough. It's not the best because the difficulty to crack the hash does not on the performance of the machine.
+The best algorithm, [Argon2](https://en.wikipedia.org/wiki/Argon2) does though. It won the
+[Password Hashing Competition](https://en.wikipedia.org/wiki/Password_Hashing_Competition) in 2015 and is now
+considered the best hashing function. There is an open [issue](https://github.com/authelia/authelia/issues/577)
+to add support for this hashing function.

+cannot detect the target URL where the user was heading.
+
+In a normal authentication workflow, a user tries to access a website and she
+gets redirected to the sign-in portal in order to authenticate. Since the user
+initially targeted a website, the portal knows where the user was heading and
+can redirect her after the authentication process.
+However, when a user visits the sign in portal directly, the portal considers
+the targeted website is the portal. In that case and if the default redirection URL
+is configured, the user is redirected to that URL. If not defined, the user is not
+redirected after authentication.

+Configuration of Authelia requires some secrets and passwords.
+Even if they can be set in the configuration file, the recommended
+way to set secrets is to use environment variables as described
+below.
+
+## Environment variables
+
+A secret can be configured using an environment variable with name
+starting with AUTHELIA_ and followed by the path of the option capitalized
+and with dots replaced by underscores.
+
+For instance the LDAP password is identified by the path
+**authentication_backend.ldap.password**, so this password could
+alternatively be set using the environment variable called
+**AUTHELIA_AUTHENTICATION_BACKEND_LDAP_PASSWORD**.
+
+Here is the list of the environment variables which are considered
+secrets and can be defined. Any other option defined using an
+environment variable will not be replaced.
+
+* AUTHELIA_JWT_SECRET
+* AUTHELIA_DUO_API_SECRET_KEY
+* AUTHELIA_SESSION_SECRET
+* AUTHELIA_AUTHENTICATION_BACKEND_LDAP_PASSWORD
+* AUTHELIA_NOTIFIER_SMTP_PASSWORD
+* AUTHELIA_SESSION_REDIS_PASSWORD
+* AUTHELIA_STORAGE_MYSQL_PASSWORD
+* AUTHELIA_STORAGE_POSTGRES_PASSWORD
+
+## Secrets in configuration file
+
+If for some reason you prefer keeping the secrets in the configuration
+file, be sure to apply the right permissions to the file in order to
+prevent secret leaks if an another application gets compromised on your
+server. The UNIX permissions should probably be something like 600.

-
-**WARNING:** *the instructions given in this documentation are not meant
-to be used for production environments since it will make **Authelia**
-non resilient to failures.*
-
-**NOTE:** If not done already, we highly recommend you first follow the
-[Getting Started] documentation.
-
-In some cases, like protecting personal projects/websites, it can be fine
-to use **Authelia** in a non highly-available setup. This reduces the number
-of components to only two: a reverse proxy such as nginx or Traefik and
-Authelia as a companion of the proxy.
-
-As for a regular deployment in production, you need to install **Authelia**
-either by pulling the Docker image or building distributable version.
-
-## Build and deploy the distributable version
-
-    $ authelia-scripts build
-    $ PUBLIC_DIR=./dist/public_html ./dist/authelia --config /path/to/your/configuration.yml
-
-## Deploy with Docker
-
-    $ docker pull authelia/authelia
-    $ docker run -v /path/to/your/configuration.yml:/etc/authelia/configuration.yml authelia/authelia
-
-## Deploy Nginx
-
-You also need to install nginx and take
-[example/compose/nginx/minimal/nginx.conf](./example/compose/nginx/minimal/nginx.conf)
-as an example for your configuration.
-
-## Deploy Traefik
-
-TODO
-
-## Discard components
-
-### Discard SQL server
-
-There is an option in the configuration file to avoid using an external
-SQL server and use a local sqlite3 database instead. This option will
-therefore prevent you from running multiple instances of **Authelia**
-in parallel.
-Consequently, this option is not meant to be used in production or at
-least not one that should scale out.
-
-Here is the configuration you should use:
-
-    storage:
-      # The file path of the sqlite3 file where data will be persisted
-      local:
-        path: /var/lib/authelia/db.sqlite3
-
-### Discard Redis
-
-There is an option in the configuration file to discard Redis and use the
-memory of the server to store the KV data. This option will therefore
-prevent you from running multiple instances of **Authelia** in parallel and
-will make you lose user sessions if the application restarts. This
-concretely means that all your users will need to authenticate again after
-a restart of Authelia. Hence, this option is not meant to be used in production.
-
-To use memory instead of a Redis backend, just comment out the Redis
-connection details in the following block:
-
-    session:
-      ...      
-      # # The redis connection details
-      # redis:
-      #  host: redis
-      #  port: 6379
-      #  password: authelia
-
-### Discard LDAP
-
-**Authelia** can use a file backend in order to store users instead of a
-LDAP server or an Active Directory. This mode will therefore prevent you
-from running multiple instances of **Authelia** in parallel and is therefore
-discouraged for production environments.
-
-To use a file backend instead of a LDAP server, you should first duplicate
-the file [users_database.yml](../test/suites/basic/users_database.yml) and
-edit it to add the users you want.
-
-The content of this file is as follows:
-
-    users:
-      ...
-      john:
-        password: "$6$rounds=500000$jgiCMRyGXzoqpxS3$w2pJeZnnH8bwW3zzvoMWtTRfQYsHbWbD/hquuQ5vUeIyl9gdwBIt6RWk2S6afBA0DPakbeWgD/4SZPiS0hYtU/"
-        email: john.doe@authelia.com
-        groups:
-          - admins
-          - dev
-
-The password is hashed and salted as it is in LDAP servers with salted SHA-512
-(more hash algorithms such as Argon2 will be provided in the future).
-Here is a one-liner to generate such hashed password:
-
-    $ docker run authelia/authelia authelia hash-password yourpassword
-    $6$rounds=50000$BpLnfgDsc2WD8F2q$PumMwig8O0uIe9SgneL8Cm1FvUniOzpqBrH.uQE3aZR4K1dHsQldu5gEjJZsXcO./v3itfz6CXTDTJgeh5e8t.
-
-Copy this newly hashed password into your `users_database.yml` file.
-
-Once the file is created, edit the configuration file with the following
-block (as used in [configuration.yml](../test/suites/basic/configuration.yml)):
-
-    authentication_backend:
-      file:
-        path: /path/to/the/users_database.yml
-
-instead of (used in [config.template.yml](../config.template.yml)):
-
-    authentication_backend:
-      ldap:
-        url: ldap://openldap
-        base_dn: dc=example,dc=com
-
-        additional_users_dn: ou=users
-        users_filter: cn={0}
-
-        additional_groups_dn: ou=groups
-        groups_filter: (&(member={dn})(objectclass=groupOfNames))
-
-        group_name_attribute: cn
-

-
-        user: cn=admin,dc=example,dc=com

-## FAQ
-
-### Can you give more details on why this is not suitable for production environments?
-
-This documentation gives instructions that will make **Authelia** non
-highly-available and non scalable by preventing you from running multiple
-instances of the application.
-This means that **Authelia** won't be able to distribute the
-load across multiple servers and it will prevent failover in case of a
-crash or an hardware issue. Moreover, it will also prevent from reliably
-persisting data and consequently fail access to your platform as the devices
-registered by your users will be lost.
-
-### Why aren't all those steps automated?
-
-Well, as stated before those instructions are not meant to be applied for
-a production environment. That being said, in some cases it is just fine and
-writing an Ansible playbook to automate all this process is ok.
-We would really be more than happy to review such a PR.
-In the meantime, you can check the *Standalone* [suite](./suites.md) to see all this
-in a real example.

-## 1-Factor (1FA) using a LDAP server
-
-**Authelia** uses an LDAP server as the backend for storing credentials.
-When authentication is needed, the user is redirected to the login page which
-corresponds to the first factor. **Authelia** tries to bind the username and
-password against the configured LDAP backend.
-
-You can find an example of the configuration of the LDAP backend in
-[config.template.yml].
-
-<p align="center">
-  <img src="../docs/images/1FA.png" width="400">

-
-## 2-Factor (2FA)
-
-**Authelia** comes with three kind of second factor.
-
-* Security keys like [Yubikey]. More info [here](./2factor/security-key.md).
-* One-Time Passwords generated by [Google Authenticator]. More info [here](./2factor/time-based-one-time-password.md).
-* Duo Push Notifications to use with [Duo mobile application](https://play.google.com/store/apps/details?id=com.duosecurity.duomobile&hl=en) available on Android, iOS and Windows. More info [here](./2factor/duo-push-notifications.md).

-
-## Password reset
-
-With **Authelia**, you can also reset your password in no time. Click on the 
-**Forgot password?** link in the login page, provide the username of the user
-requiring a password reset and **Authelia** will send an email a confirmation
-email to the user email address.
-
-Proceed with the password reset form and validate to reset your password.

-
-## Access Control
-
-With **Authelia**, you can define your own access control rules for finely
-restricting user access to some resources and subdomains. Those rules are
-defined and fully documented in the configuration file. They can apply to
-users, groups or everyone.
-
-Check out [config.template.yml] to see how they are defined.
-
-## Single factor authentication
-
-**Authelia** allows you to customize the authentication method to use for each 
-subdomain. The supported methods are either "single_factor" or "two_factor". 
-Please check [config.template.yml] to see an example of configuration.
-
-It is also possible to use [basic authentication] to access a resource 
-protected by a single factor.
-
-Please note that Authelia uses the *Proxy-Authorization* header and not
-*Authorization* since one might be willing to authenticate against both
-Authelia and the proxy. For instance you can use the following command to
-access your service:
-
-    $ curl -H "Proxy-Authorization: Basic am9objpwYXNzd29yZA==" https://myservice.example.com"
-
-## Session management with Redis
-
-When your users authenticate against Authelia, sessions are stored in a
-Redis key/value store. You can specify your own Redis instance in
-[config.template.yml].

+# Access Control
+
+**Authelia** allows to define a fine-grained rule-based access control policy in
+configuration. This list of rules is tested against any requests protected by
+Authelia and defines the level of authentication the user must pass to get access
+to the resource.
+
+For instance a rule can look like this:
+
+    - domain: dev.example.com
+      resources:
+        - "^/groups/dev/.*$"
+      subject: "group:dev"
+      policy: two_factor
+
+This rule matches when the request targets the domain `dev.example.com` and the path
+matches the regular expression `^/groups/dev/.*$`. In that case, a two-factor policy
+is applied requiring the user to authenticate with two factors.

+# Regulation
+
+**Authelia** takes the security of users very seriously and comes with
+a way to avoid brute forcing the first factor by regulating the
+authentication attempts and temporarily ban an account when too many
+attempts have been made.
+
+## Configuration
+
+Please check the dedicated [documentation](./deployement/configuration/regulation.md).

+# Single Factor
+
+**Authelia** supports single factor authentication to let applications
+send authenticated requests to other applications.
+
+Single or two-factor authentication can be configured per resource of an
+application for flexibility.
+
+For instance, you can configure Authelia to grant access to all resources
+matching `app1.example.com/api/(.*)` with only a single factor and all
+resources matching `app1.example.com/admin` with two factors.
+
+To know more about the configuration of the feature, please visit the
+documentation about the [configuration](../deployment/configuration.md).
+
+
+## Proxy-Authorization header
+
+Authelia reads credentials from the header `Proxy-Authorization` instead of
+the usual `Authorization` header. This is because in some circumstances both Authelia
+and the application could require authentication in order to provide specific
+authorizations at the level of the application.

+# Architecture
+
+**Authelia** is a companion of reverse proxies like Nginx, Traefik and HAProxy.
+It can be seen as an extension of those proxies providing authentication functions
+and a login portal.
+
+As shown in the following architecture diagram, Authelia is directly connected to
+the reverse proxy but never directly connected to application backends.
+
+<p align="center" style="margin:50px">
+  <img src="../images/archi.png"/>
+</p>
+
+## Workflow
+
+Reverse proxies are configured so that every incoming requests generates an authentication
+request sent to Authelia and to which Authelia responds to order the reverse
+proxy to let the incoming request pass through or block it because user is not authenticated
+or is not sufficiently authorized.
+
+### Step by step
+
+When the first request of an unauthenticated user hits the reverse proxy, Authelia
+determines the user is not authenticated because no session cookie has been sent along with
+the request. Consequently, Authelia redirects the user to the authentication portal provided
+by Authelia itself. The user can then execute the authentication workflow using that portal
+to obtain a session cookie valid for all subdomains of the domain protected by Authelia.
+
+When the user visits the initial website again, the query is sent along with the
+session cookie which is forwarded in the authentication request to Authelia. This time,
+Authelia can verify the user is authenticated and order the reverse proxy to let the query
+pass through.
+
+### Sequence Diagram
+
+Here is a description of the complete workflow:
