I just logged into M4C and FireFox gave me a warning that my username and password could be compromised.
Quote from my web browser, "About insecure pages
Pages that need to transmit private information, such as credit cards, personal information and passwords, need to have a secure connection to help prevent attackers from stealing your information. (Tip: A secure connection will have "HTTPS" in the address bar, along with a green lock icon.) "

Is there a way to login securely?
