# `--netrc`
Make curl scan the *.netrc* file in the user's home directory for login name
and password. This is typically used for FTP on Unix. If used with HTTP, curl
enables user authentication. See *netrc(5)* and *ftp(1)* for details on the
file format. curl does not complain if that file does not have the right
permissions (it should be neither world- nor group-readable). The environment
variable `HOME` is used to find the home directory. If the `NETRC` environment
variable is set, that filename is used as the netrc file. (Added in 8.16.0)
If --netrc-file is used, that overrides all other ways to figure out the file.
The netrc file provides credentials for a hostname independent of which
protocol and port number that are used.
On Windows two filenames in the home directory are checked: *.netrc* and
*_netrc*, preferring the former. Older versions on Windows checked for
*_netrc* only.
A quick and simple example of how to setup a *.netrc* to allow curl to FTP to
the machine host.example.com with username 'myself' and password 'secret'
could look similar to:
machine host.example.com
login myself
password secret
