CURLOPT_USERPWD(3)

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]:[password]. 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@example.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 only sends this user and password information to hosts using the initial host name (unless CURLOPT_UNRESTRICTED_AUTH(3) is set), so if libcurl follows redirects to other hosts, it does 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 is no way to send in a user name containing a colon using this option. Use CURLOPT_USERNAME(3) for that, or include it in the URL. The application does not have to keep the string around after setting this option.
