NAME
       CURLOPT_USERPWD - user name and password to use in authentication

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERPWD, char *userpwd);

DESCRIPTION
       Pass a char * as parameter, pointing to a null-terminated login details
       string for the connection. The format of which is:  [user  name]:[pass-
       word].

       When  using Kerberos V5 authentication with a Windows based server, you
       should specify the user name part with 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 user name can be specified simply as the user name
       without  the  domain  name should the server be part of a single domain
       and forest.

       To specify the domain name use either  Down-Level  Logon  Name  or  UPN
       (User Principal Name) formats. For example, EXAMPLE\user and user@exam-
       ple.com respectively.

       Some HTTP servers (on Windows) support  inclusion  of  the  domain  for
       Basic authentication as well.

       When  using  HTTP  and CURLOPT_FOLLOWLOCATION(3), libcurl might perform
       several requests to possibly different hosts. libcurl  will  only  send
       this user and password information to hosts using the initial host name
       (unless CURLOPT_UNRESTRICTED_AUTH(3) is set),  so  if  libcurl  follows
       locations  to  other  hosts  it  will not send the user and password to
       those. This is enforced to prevent accidental information leakage.

       Use CURLOPT_HTTPAUTH(3) to specify the authentication method  for  HTTP
       based connections or CURLOPT_LOGIN_OPTIONS(3) to control IMAP, POP3 and
       SMTP options.

       The user and password strings are not URL decoded, so there's no way to
       send  in  a  user  name  containing a colon using this option. Use CUR-
       LOPT_USERNAME(3) for that, or include it in the URL.

       The application does not have to keep the string around  after  setting
       this option.

DEFAULT
       NULL

PROTOCOLS
       Most

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");

         curl_easy_setopt(curl, CURLOPT_USERPWD, "clark:kent");

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns  CURLE_OK on success or CURLE_OUT_OF_MEMORY if there was insuf-
       ficient heap space.
