You'll get that warning from browsers these days, If there isn't an SSL certificate on the url (https vs http or the little lock icon that shows up when shopping online) to encrypt the back and forth communication. Chrome gives an advance button where you can opt to proceed anyway. It's a good warning because most legit sites have a security certificate(if they don't, they should)....sorry for the techy talk. I'm a programming IT nerd by occupation.
