+Long: anyauth
+Help: Pick any authentication method
+Protocols: HTTP
+See-also: proxy-anyauth basic digest
+---
+Tells curl to figure out authentication method by itself, and use the most
+secure one the remote site claims to support. This is done by first doing a
+request and checking the response-headers, thus possibly inducing an extra
+network round-trip. This is used instead of setting a specific authentication
+method, which you can do with --basic, --digest, --ntlm, and --negotiate.
+
+Using --anyauth is not recommended if you do uploads from stdin, since it may
+require data to be sent twice and then the client must be able to rewind. If
+the need should arise when uploading from stdin, the upload operation will
+fail.
+
+Used together with --user.
