+# NAME
+
+CURLOPT_USERNAME - username to use in authentication
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERNAME,
+                          char *username);
+~~~
+
+# DESCRIPTION
+
+Pass a char pointer as parameter, which should be pointing to the
+null-terminated username to use for the transfer.
+
+CURLOPT_USERNAME(3) sets the username to be used in protocol
+authentication. You should not use this option together with the (older)
+CURLOPT_USERPWD(3) option.
+
+When using Kerberos V5 authentication with a Windows based server, you should
+include the domain name in order for the server to successfully obtain a
+Kerberos Ticket. If you do not then the initial part of the authentication
+handshake may fail.
+
+When using NTLM, the username can be specified simply as the username without
+the domain name should the server be part of a single domain and forest.
+
+To include the domain name use either Down-Level Logon Name or UPN (User
+Principal Name) formats. For example, **EXAMPLE\user** and
+**user@example.com** respectively.
+
+Some HTTP servers (on Windows) support inclusion of the domain for Basic
+authentication as well.
+
+To specify the password and login options, along with the username, use the
+CURLOPT_PASSWORD(3) and CURLOPT_LOGIN_OPTIONS(3) options.
+
+The application does not have to keep the string around after setting this
+option.
