\C{config} Configuring PuTTY
\b Username and password authentication is supported for HTTP
proxies and SOCKS 5 proxies.
+\lcont{
+
+\b With SOCKS 5, authentication is via \i{CHAP} if the proxy
+supports it (this is not supported in \i{PuTTYtel}); otherwise the
+password is sent to the proxy in plain text.
+
+\b With HTTP proxying, the only currently supported authentication
+method is \q{basic}, where the password is sent to the proxy in plain
+text.
+
+}
+
\b SOCKS 4 can use the \q{Username} field, but does not support
passwords.
