-**TODO**
+[Ad-Hoc command][XEP-0050] interface to
+[dynamic OAuth2 registration](https://oauth.net/2/dynamic-client-registration/)
+provided by [mod_http_oauth2].
 
 Compatibility
 =============
 
-Probably Prosody trunk.
+Same as [mod_http_oauth2]

+## Viewing the log
+
+You can view the log using prosodyctl. This works even when Prosody is not
+running.
+
+For example, to view the full audit log for example.com:
+
+```shell
+prosodyctl mod_audit example.com
+```
+
+To view only host-wide events (those not attached to a specific user account),
+use the `--global` option (or use `--no-global` to hide such events):
+
+```shell
+prosodyctl mod_audit --global example.com
+```
+
+To narrow results to a specific user, specify their JID:
+
+```shell
+prosodyctl mod_audit user@example.com
+```

+rockspec: {}
+...
+
+This module records server status (start, stop, crash) to the audit log
+maintained by [mod_audit].
+
+## Configuration
+
+There is a single option, `audit_status_heartbeat_interval` which specifies
+the interval at which the "server is running" heartbeat should be updated (it
+is stored in Prosody's configured storage backend).
+
+To detect crashes, Prosody periodically updates this value at the specified
+interval. A low value will update more frequently, which causes additional I/O
+for Prosody. A high value will give less accurate timestamps for "server
+crashed" events in the audit log.
+
+The default value is 60 (seconds).
+
+```lua
+audit_status_heartbeat_interval = 60
+```
+
+## Compatibility
+
+This module requires Prosody trunk (as of April 2023). It is not compatible
+with 0.12.

+summary: Authenticate against an external OAuth 2 IdP
+labels:
+- Stage-Alpha
+---
+
+This module provides external authentication via an external [AOuth
+2](https://datatracker.ietf.org/doc/html/rfc7628) authorization server
+and supports the [SASL OAUTHBEARER authentication][rfc7628]
+mechanism as well as PLAIN for legacy clients (this is all of them).
+
+# How it works
+
+Clients retrieve tokens somehow, then show them to Prosody, which asks
+the Authorization server to validate them, returning info about the user
+back to Prosody.
+
+Alternatively for legacy clients, Prosody receives the users username
+and password and retrieves a token itself, then proceeds as above.
+
+# Configuration
+
+## Example
+
+```lua
+-- authentication = "oauth_external"
+
+oauth_external_discovery_url = "https//auth.example.com/auth/realms/TheRealm/.well-known/openid-configuration"
+oauth_external_token_endpoint = "https//auth.example.com/auth/realms/TheRealm/protocol/openid-connect/token"
+oauth_external_validation_endpoint = "https//auth.example.com/auth/realms/TheRealm/protocol/openid-connect/userinfo"
+oauth_external_username_field = "xmpp_username"
+```
+
+
+## Common
+
+`oauth_external_issuer`
+:   Optional URL string representing the Authorization server identity.
+
+`oauth_external_discovery_url`
+:   Optional URL string pointing to [OAuth 2.0 Authorization Server
+    Metadata](https://oauth.net/2/authorization-server-metadata/). Lets
+    clients discover where they should retrieve access tokens from if
+    they don't have one yet. Default based on `oauth_external_issuer` is
+    set, otherwise empty.
+
+`oauth_external_validation_endpoint`
+:   URL string. The token validation endpoint, should validate the token
+    and return a JSON structure containing the username of the user
+    logging in the field specified by `oauth_external_username_field`.
+    Commonly the [OpenID `UserInfo`
+    endpoint](https://openid.net/specs/openid-connect-core-1_0.html#UserInfo)
+
+`oauth_external_username_field`
+:   String. Default is `"preferred_username"`. Field in the JSON
+    structure returned by the validation endpoint that contains the XMPP
+    localpart.
+
+## For SASL PLAIN
+
+`oauth_external_resource_owner_password`
+:   Boolean. Defaults to `true`. Whether to allow the *insecure*
+    [resource owner password
+    grant](https://oauth.net/2/grant-types/password/) and SASL PLAIN.
+
+`oauth_external_token_endpoint`
+:   URL string. OAuth 2 [Token
+    Endpoint](https://www.rfc-editor.org/rfc/rfc6749#section-3.2) used
+    to retrieve token in order to then retrieve the username.
+
+`oauth_external_client_id`
+:   String. Client ID used to identify Prosody during the resource owner
+    password grant.

+summary: Authorization delegation
+rockspec: {}
+...
+
+This module allows delegating authorization questions (role assignment and
+role policies) to another host within prosody.
+
+The primary use of this is for a group of virtual hosts to use a common
+authorization database, for example to allow a MUC component to grant
+administrative access to an admin on a corresponding user virtual host.
+
+## Configuration
+
+The following example will make all role assignments for local and remote JIDs
+from domain.example effective on groups.domain.example:
+
+```
+VirtualHost "domain.example"
+
+Component "groups.domain.example" "muc"
+    authorization = "delegate"
+    authz_delegate_to = "domain.example"
+```

+---
+
+This module allows a user to identify what currently has access to their
+account.
+
+This module depends on [mod_sasl2_fast] and mod_tokenauth (bundled with
+Prosody). Both will be automatically loaded if this module is loaded.
+
+## Configuration
+
+| Name                      | Description                                            | Default         |

+| enforce_client_ids        | Only allow SASL2-compatible clients                    | `false`         |
+
+When `enforce_client_ids` is not enabled, the client listing may be less accurate due to legacy clients,
+which can only be tracked by their resource, which is public information, not necessarily unique to a
+client instance, and is also exposed to other XMPP entities the user communicates with.
+
+When `enforce_client_ids` is enabled, clients that don't support SASL2 and provide a client id will be
+denied access.
+
+## Shell usage
+
+You can use this module via the Prosody shell. For example, to list a user's
+clients:
+
+```shell
+prosodyctl shell user clients user@example.com
+```
+
+## Compatibility
+
+Requires Prosody trunk (as of 2023-03-29). Not compatible with Prosody 0.12
+and earlier.
+
+## Developers
+
+### Protocol
+
+#### Listing clients
+
+To list clients that have access to the user's account, send the following
+stanza:
+
+```xml
+<iq id="p" type="get">
+  <list xmlns="xmpp:prosody.im/protocol/manage-clients"/>
+</iq>
+```
+
+The server will respond with a list of clients:
+
+```xml
+<iq id="p" to="mattj-gajim@auth2.superxmpp.com/gajim.UYJKBHKT" type="result" xmlns="jabber:client">
+  <clients xmlns="xmpp:prosody.im/protocol/manage-clients">
+    <client connected="true" id="client/zeiP41HLglIu" type="session">
+      <first-seen>2023-04-06T14:26:08Z</first-seen>
+      <last-seen>2023-04-06T14:37:25Z</last-seen>
+      <auth>
+        <password/>
+      </auth>
+      <user-agent>
+        <software>Gajim</software>
+        <uri>https://gajim.org/</uri>
+        <device>Juliet's laptop</device>
+      </user-agent>
+    </client>
+    <client connected="false" id="grant/HjEEr45_LQr" type="access">
+      <first-seen>2023-03-27T15:16:09Z</first-seen>
+      <last-seen>2023-03-27T15:37:24Z</last-seen>
+      <user-agent>
+        <software>REST client</software>
+      </user-agent>
+    </client>
+  </clients>
+</iq>
+```
+
+On the `<client/>` tag most things are self-explanatory. The following attributes
+are defined:
+
+- 'connected': a boolean that reflects whether this client has an active session
+on the server (i.e. this includes connected and "hibernating" sessions).
+- 'id': an opaque reference for the client, which can be used to revoke access.
+- 'type': either `"session"` if this client is known to have an active or inactive
+  client session on the server, or "access" if no session has been established (e.g.
+  it may have been granted access to the account, but only used non-XMPP APIs or
+  never logged in).
+
+The `<first-seen/>` and `<last-seen/>` elements contain timestamps that reflect
+when a client was first granted access to the user's account, and when it most
+recently used that access. For active sessions, it may reflect the current
+time or the time of the last login.
+
+The `<user-agent/>` element contains information about the client software. It
+may contain any of three optional child elements, each containing text content:
+
+- `<software/>` - the name of the software
+- `<uri/>` - a URI/URL for the client, such as a homepage
+- `<device/>` - a human-readable identifier/name for the device where the client
+  runs
+
+The `<auth/>` element lists the known authentication methods that the client
+has used to gain access to the account. The following elements are defined:
+
+- `<password/>` - the client has presented a valid password
+- `<grant/>` - the client has a valid authorization grant (e.g. via OAuth)
+- `<fast/>` - the client has active FAST tokens
+
+#### Revoking access
+
+To revoke a client's access, send a `<revoke/>` element with an 'id' attribute
+containing one of the client ids fetched from the list:
+
+```xml
+<iq id="p" type="set">
+  <revoke xmlns="xmpp:prosody.im/protocol/manage-clients" id="grant/HjEEr45_LQr" />
+</iq>
+```
+
+The server will respond with an empty result if the revocation succeeds:
+
+```xml
+<iq id="p" type="result" />
+```
+
+If the client has previously authenticated with a password, there is no way to
+revoke access except by changing the user's password. If you request
+revocation of such a client, the server will respond with a 'service-unavailable'
+error, with the 'password-reset-required' application error:
+
+```xml
+<iq id="p" type="error">
+  <error type="cancel">
+    <service-unavailable xmlns="xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'">
+    <password-reset-required xmlns="xmpp:prosody.im/protocol/manage-clients"/>
+  </error>
+</iq>
+```

-Introduction
-============
+## Introduction
+
+This module implements an [OAuth2](https://oauth.net/2/)/[OpenID Connect
+(OIDC)](https://openid.net/connect/) provider HTTP frontend on top of
+Prosody's usual internal authentication backend.
+
+OAuth and OIDC are web standards that allow you to provide clients and
+third-party applications limited access to your account, without sharing your
+password with them.
+
+With this module deployed, software that supports OAuth can obtain "access
+tokens" from Prosody which can then be used to connect to XMPP accounts using
+the 'OAUTHBEARER' SASL mechanism or via non-XMPP interfaces such as [mod_rest].
+
+Although this module has been around for some time, it has recently been
+significantly extended and largely rewritten to support OAuth/OIDC more fully.
+
+As of April 2023, it should be considered **alpha** stage. It works, we have
+tested it, but it has not yet seen wider review, testing and deployment. At
+this stage we recommend it for experimental and test deployments only. For
+specific information, see the [deployment notes section](#deployment-notes)
+below.
+
+Known client implementations:
+
+-   [example shell script for mod_rest](https://hg.prosody.im/prosody-modules/file/tip/mod_rest/example/rest.sh)
+-   *(we need you!)*
+
+Support for OAUTHBEARER has been added to the Lua XMPP library, [verse](https://code.matthewwild.co.uk/verse).
+If you know of additional implementations, or are motivated to work on one,
+please let us know! We'd be happy to help (e.g. by providing a test server).
+
+## Standards support
+
+Notable supported standards:
 
-This module is a work-in-progress intended for developers only!
+- [RFC 6749: The OAuth 2.0 Authorization Framework](https://www.rfc-editor.org/rfc/rfc6749)
+- [RFC 7009: OAuth 2.0 Token Revocation](https://www.rfc-editor.org/rfc/rfc7009)
+- [RFC 7628: A Set of Simple Authentication and Security Layer (SASL) Mechanisms for OAuth](https://www.rfc-editor.org/rfc/rfc7628)
+- [RFC 7636: Proof Key for Code Exchange by OAuth Public Clients](https://www.rfc-editor.org/rfc/rfc7636)
+- [OpenID Connect Core 1.0](https://openid.net/specs/openid-connect-core-1_0.html)
+- [OpenID Connect Dynamic Client Registration 1.0](https://openid.net/specs/openid-connect-registration-1_0.html) & [RFC 7591: OAuth 2.0 Dynamic Client Registration](https://www.rfc-editor.org/rfc/rfc7591.html)
+- [OpenID Connect Discovery 1.0](https://openid.net/specs/openid-connect-discovery-1_0.html)
+
+## Configuration
+
+### Interface
+
+The module presents a web page to users to allow them to authenticate when
+a client requests access. Built-in pages are provided, but you may also theme
+or entirely override them.
+
+This module honours the 'site_name' configuration option that is also used by
+a number of other modules:
+
+```lua
+site_name = "My XMPP Server"
+```
+
+To provide custom templates, specify the path to the template directory:
+
+```lua
+oauth2_template_path = "/etc/prosody/custom-oauth2-templates"
+```
+
+Some templates support additional variables, that can be provided by the
+'oauth2_template_style' option:
+
+```lua
+oauth2_template_style = {
+  background_colour = "#ffffff";
+}
+```
+
+### Token parameters
+
+The following options configure the lifetime of tokens issued by the module.
+The defaults are recommended.
+
+```lua
+oauth2_access_token_ttl = 86400 -- 24 hours
+oauth2_refresh_token_ttl = nil -- unlimited unless revoked by the user
+```
 
-Configuration
-=============
+### Dynamic client registration
+
+To allow users to connect any compatible software, you should enable dynamic
+client registration.
+
+Dynamic client registration can be enabled by configuring a JWT key. Algorithm
+defaults to *HS256* lifetime defaults to forever.
+
+```lua
+oauth2_registration_key = "securely generated JWT key here"
+oauth2_registration_algorithm = "HS256"
+oauth2_registration_ttl = nil -- unlimited by default
+```
+
+### Supported flows
+
+Various flows can be disabled and enabled with
+`allowed_oauth2_grant_types` and `allowed_oauth2_response_types`:
 
-None currently.
+```lua
+allowed_oauth2_grant_types = {
+	"authorization_code"; -- authorization code grant
+	"password"; -- resource owner password grant
+}
+
+allowed_oauth2_response_types = {
+	"code"; -- authorization code flow
+    -- "token"; -- implicit flow disabled by default
+}
+```
+
+The [Proof Key for Code Exchange][RFC 7636] mitigation method can be
+made required:
+
+```lua
+oauth2_require_code_challenge = true
+```
+
+Further, individual challenge methods can be enabled or disabled:
 
-Compatibility
-=============
+```lua
+allowed_oauth2_code_challenge_methods = {
+    "plain"; -- the insecure one
+    "S256";
+}
+```
+
+### Policy documents
+
+Links to Terms of Service and Service Policy documents can be advertised
+for use by OAuth clients:
+
+```lua
+oauth2_terms_url = "https://example.com/terms-of-service.html"
+oauth2_policy_url = "https://example.com/service-policy.pdf"
+```
+
+## Deployment notes
+
+### Access management
 
-Requires Prosody 0.12+ or trunk.
+This module does not provide an interface for users to manage what they have
+granted access to their account! (e.g. to view and revoke clients they have
+previously authorized). It is recommended to join this module with
+mod_client_management to provide such access. However, at the time of writing,
+no XMPP clients currently support the protocol used by that module. We plan to
+work on additional interfaces in the future.
+
+### Scopes
+
+OAuth supports "scopes" as a way to grant clients limited access.
+
+There are currently no standard scopes defined for XMPP. This is something
+that we intend to change, e.g. by definitions provided in a future XEP. This
+means that clients you authorize currently have unrestricted access to your
+account (including the ability to change your password and lock you out!). So,
+for now, while using OAuth clients can prevent leaking your password to them,
+it is not currently suitable for connecting untrusted clients to your account.
+
+## Compatibility
+
+Requires Prosody trunk (April 2023), **not** compatible with Prosody 0.12 or
+earlier.

+This module extracts profile details from the user's [vcard4][XEP-0292]
+and provides them in the [UserInfo] endpoint of [mod_http_oauth2] to
+clients the user grants authorization.
+
+Whether this is really needed is unclear at this point. When logging in

+details, so the UserInfo details would probably primarily be useful to

+This module allows advertising a machine-readable document were outages,
+planned or otherwise, may be reported.
+
+See [XEP-0455: Service Outage Status] for further details, including
+the format of the outage status document.
+
+```lua
+modules_enabled = {
+    -- other modules
+    "service_outage_status",
+}
+
+outage_status_urls = {
+    "https://uptime.example.net/status.json",
+}
+```
+
+The outage status document should be hosted on a separate server to
+ensure availability even if the XMPP server is unreachable.

+summary: 'Forward spam/abuse reports to a JID'
+---
+
+This module forwards spam/abuse reports (e.g. those submitted by users via
+XEP-0377 via mod_spam_reporting) to one or more JIDs.
+
+## Configuration
+
+Install and enable the module the same as any other.
+
+There is a single option, `spam_report_destinations` which accepts a list of
+JIDs to send reports to.
+
+For example:
+
+```lua
+modules_enabled = {
+    ---
+    "spam_reporting";
+    "spam_report_forwarder";
+    ---
+}
+
+spam_report_destinations = { "antispam.example.com" }
+```
+
+## Protocol
+
+This section is intended for developers.
+
+XEP-0377 assumes the report is embedded within another protocol such as
+XEP-0191, and doesn't specify a format for communicating "standalone" reports.
+This module transmits them inside a `<message>` stanza, and adds a `<jid/>`
+element (borrowed from XEP-0268):
+
+```xml
+<message from="prosody.example" to="destination.example">
+    <report xmlns="urn:xmpp:reporting:1" reason="urn:xmpp:reporting:spam">
+        <jid xmlns="urn:xmpp:jid:0">spammer@bad.example</jid>
+        <text>
+          Never came trouble to my house like this.
+        </text>
+    </report>
+</message>
+```

-Introduction
-============
+# Introduction
 
-This module implements [HTTP Strict Transport
-Security](https://tools.ietf.org/html/rfc6797) and responds to all
-non-HTTPS requests with a `301 Moved Permanently` redirect to the HTTPS
-equivalent of the path.
+This module implements [RFC 6797: HTTP Strict Transport Security] and
+responds to all non-HTTPS requests with a `301 Moved Permanently`
+redirect to the HTTPS equivalent of the path.
 
-Configuration
-=============
+# Configuration
 
 Add the module to the `modules_enabled` list and optionally configure
 the specific header sent.
 
-    modules_enabled = {
-      ...
-          "strict_https";
-    }
-    hsts_header = "max-age=31556952"
+``` lua
+modules_enabled = {
+  ...
+      "strict_https";
+}
+hsts_header = "max-age=31556952"
+```
+
+If the redirect from `http://` to `https://` causes trouble with
+internal use of HTTP APIs it can be disabled:
