At present there doesn't seem to be an easy way to login securely using the Member module. Safecraker provides useful parameters in secure_action="yes" and secure_return="yes" to ensure encrypted submissions but the login form is left wide open by default (which is a unbelievable!).
How do other people handle secure login form submissions to ensure they are posted over HTTPS in the lack of a built in facility by default in EE?
I know that FreeMember has recently has this support added but if I'm not using FreeMember than I'd like to be able to find a way to secure my logins.
UPDATE: It looks like Zoo Visitor also supports secure login forms and it's now just been added to the docs with the same parameters as Safecracker.
