# `--proxy-user`
|
|
|
|
Specify the username and password to use for proxy authentication.
|
|
|
|
If you use a Windows SSPI-enabled curl binary and do either Negotiate or NTLM
|
|
authentication then you can tell curl to select the username and password from
|
|
your environment by specifying a single colon with this option: "-U :".
|
|
|
|
On systems where it works, curl hides the given option argument from process
|
|
listings. This is not enough to protect credentials from possibly getting seen
|
|
by other users on the same system as they still are visible for a moment
|
|
before cleared. Such sensitive data should be retrieved from a file instead or
|
|
similar and never used in clear text in a command line.
