The website security has been updated so that any data that you send to or receive from the website can not be intercepted by anyone. The connection that is established between the website is accomplished using SSL technology. SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral.
Since this is a free website, the only data that should be of concern is your password, and it is now fully encrypted when sent to the server.
