| 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 |
| https://datatracker.ietf.org/doc/html/draft-earhart-url-smtp-00. |
| |
| 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). |
