+### Changing the default Icecast passwords {#icecast}
+
+Random passwords are generated for Icecast during the installation. To look up and change the passwords, look in the file below.
+
+`/etc/icecast2/icecast.xml`
+
+Replace the admin and `changeme` field below with your own username and password.
+
+```
+<authentication>
+    <!-- Sources log in with username 'source' -->
+    <source-password>changeme</source-password>
+    <!-- Relays log in with username 'relay' -->
+    <relay-password>changeme</relay-password>
+    <!-- Admin logs in with the username given below -->
+    <admin-user>admin</admin-user>
+    <admin-password>changeme</admin-password>
+  </authentication>
+```
+
+Then, restart your icecast2 service.
+
+```
+service icecast2 restart
+```
+
+> Note: If you change the source password, you may need to manually configure Libretime to use the new password: go to **Settings** > **Streams**, set the streaming server to **Custom** and fill out the **Additional Options** below Stream 1.

 ### API client configuration {#api}
 
 The LibreTime API enables many types of information about the broadcast schedule and configuration to be retrieved from the LibreTime server. Other than the live-info and week-info data fetched by website widgets (see the chapter *Exporting the schedule*), all API requests must be authenticated using the secret API key stored in the file */etc/airtime/api\_client.cfg* on the LibreTime server. This key is autogenerated during LibreTime installation and should be unique for each server.
 
 If you intend to use the LibreTime API across a public network, for security reasons it is highly recommended that all API requests are sent over encrypted https: and that the web server is configured to accept requests to the api/ directory from specific host names or IP addresses only.
 
-The format of API requests is:
-
-    https://libretime.example.com/api/api-action/format/json/api_key/XXXXXX
-
-where api-action is the type of request and XXXXXX is the secret API key. Available actions include:
-
--   on-air-light - return true if the station is on air
--   status - get the status of LibreTime components and resource usage
--   version - returns the version of LibreTime installed
--   get-files-without-silan-value - list files for which silence detection has not yet been performed
--   get-stream-setting - gets the settings of LibreTime output streams
--   get-stream-parameters - gets the parameters of LibreTime output streams
-
-For example, using the action *get-stream-setting* returns the following output for the first configured stream:
-
-    {"keyname":"s1_type","value":"ogg","type":"string"},
-
-    {"keyname":"s1_host","value":"streaming.example.com","type":"string"},
-
-    {"keyname":"s1_port","value":"8000","type":"integer"},
-
-    {"keyname":"s1_mount","value":"airtime_128","type":"string"},
-
-    {"keyname":"s1_url","value":"http:\/\/airtime.sourcefabric.org","type":"string"},
-
-    {"keyname":"s1_description","value":"Airtime Radio! Stream
-    #1","type":"string"},
-
-    {"keyname":"s1_genre","value":"Screamo","type":"string"},
-
-which is enough information to construct a player widget dynamically. (s1\_url is the station's homepage, not the stream URL). The same information is provided with an s2\_ prefix for the second stream, and s3\_ prefix for the third stream.
-
-Some API requests require the directory ID number to be specified as *dir\_id* including:
-
--   list-all-files - list files in the specified directory
--   get-files-without-replay-gain - list files in the specified directory for which ReplayGain has not been calculated yet
-
-For example, using a request such as:
-
-     http://libretime.example.com/api/list-all-files/format/json/api_key/XXXXXX/dir_id/1/
-
-returns the full path to each media file in the LibreTime storage directory:
-
-```
-    {"files":[
-    "imported\/1\/Mark Ronson feat. Saigon\/Here Comes the Fuzz\/7-Diduntdidunt-unknown.flac",
-    "imported\/1\/Jimi Tenor & Tony Allen\/Inspiration Information\/3-Selfish Gene-128kbps.mp3",
-    "]}
-```
-
 If you have changed the *base\_url*, *base\_port* or *base\_dir* setting in */etc/airtime/airtime.conf* from the defaults, you will probably also have to update the *Hostname* settings in the file */etc/airtime/api\_client.cfg* accordingly.**
