+Authentication with .netrc file
+
+You may also want to configure automatic credentials storage for
+extractors that support authentication (by providing login and password
+with --username and --password) in order not to pass credentials as
+command line arguments on every youtube-dl execution and prevent
+tracking plain text passwords in shell command history. You can achieve
+this using .netrc file on per extractor basis. For that you will need to
+create .netrc file in your $HOME and restrict permissions to read/write
+by you only:
+
+ touch $HOME/.netrc
+ chmod a-rwx,u+rw $HOME/.netrc
+
+After that you can add credentials for extractor in the following
+format, where _extractor_ is the name of extractor in lowercase:
+
+ machine <extractor> login <login> password <password>
+
+For example:
+
+ machine youtube login myaccount@gmail.com password my_youtube_password
+ machine twitch login my_twitch_account_name password my_twitch_password
+
+To activate authentication with .netrc file you should pass --netrc to
+youtube-dl or to place it in configuration file.
+
+On Windows you may also need to setup %HOME% environment variable
+manually.
