# `--login-options`
|
||
|
|
|
||
|
|
Specify the login options to use during server authentication.
|
||
|
|
|
||
|
|
You can use login options to specify protocol specific options that may be
|
||
|
|
used during authentication. At present only IMAP, POP3 and SMTP support login
|
||
|
|
options. For more information about login options please see RFC 2384,
|
||
|
|
RFC 5092 and the IETF draft

Since 8.2.0, IMAP supports the login option `AUTH=+LOGIN`. With this option,
|
||
|
|
curl uses the plain (not SASL) `LOGIN IMAP` command even if the server
|
||
|
|
advertises SASL authentication. Care should be taken in using this option, as
|
||
|
|
it sends your password over the network in plain text. This does not work if
|
||
|
|
the IMAP server disables the plain `LOGIN` (e.g. to prevent password
|
||
|
|
snooping).
