In my opinion, if you want to mitigate this, don't use passwords. Use
true challenge-response. Everything else proposed here is either
obfuscation or doesn't really work in a web application environment.
A VPN around a webserver only works if every user that needs access to
that webserver can also access the vpn.

This situation should NOT be described as a 'password in cleartext'.
If you call SSL encryption (when using a decent symmetric algorithm),
then this is not a cleartext issue... You've committed a
man-in-the-middle attack by being the client AND the
man-in-the-middle... That doesn't really get you anything. If you
control the client, you control the connection. In this case, you
told your client to trust a self-signed certificate with the name of
"WebScarab" when you went to "OtherSite.

Follow NIST SP 800-63 for more guidance --
