CURLOPT\_PASSWORD(3) Library Functions Manual CURLOPT\_PASSWORD(3)

# [NAME](#NAME)

CURLOPT\_PASSWORD - password to use in authentication

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#DESCRIPTION)

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

The [*CURLOPT\_PASSWORD(3)*](/man/os/curl/CURLOPT_PASSWORD.3) option should be used in conjunction with the [*CURLOPT\_USERNAME(3)*](/man/os/curl/CURLOPT_USERNAME.3) 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.
