# CURLOPT\_PROXYPASSWORD(3)

password to use with proxy authentication

## NAME

CURLOPT\_PROXYPASSWORD - password to use with proxy authentication

## SYNOPSIS

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYPASSWORD, char *pwd);
```

## DESCRIPTION

Pass a char pointer as parameter, which should be pointing to the null-terminated password to use for authentication with the proxy.

The *[CURLOPT\_PROXYPASSWORD(3)](/CURLOPT_PROXYPASSWORD/3.md)* option should be used in conjunction with the *[CURLOPT\_PROXYUSERNAME(3)](/CURLOPT_PROXYUSERNAME/3.md)* option.

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

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

## DEFAULT

blank

## PROTOCOLS

This functionality affects all supported protocols

## EXAMPLE

```
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
    curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
    curl_easy_setopt(curl, CURLOPT_PROXYUSERNAME, "mrsmith");
    curl_easy_setopt(curl, CURLOPT_PROXYPASSWORD, "qwerty");
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
```

## AVAILABILITY
