Generally speaking I won't use a "login with facebook" option, but I will do it if there is a compelling reason. Your website has absolutely no good information about your product or what I might expect to happen after I log in, aside from a generic/broad mission statement. Regardless of your authentication options, I'm not going to try a service that I can't find any real information about.
