What are HTTP and HTTPS?
HTTP (HyperText Transfer Protocol) is a protocol used to send data over the internet. HTTPS (HyperText Transfer Protocol using Secure Socket Layer) is a protocol that encrypts data to send it over the internet more safely. When you enter a URL into a browser, the address will begin with either HTTP or HTTPS (as in https://www.paypal.com). HTTP isn’t encrypted and, as such, can be more vulnerable to hackers and fraudsters. HTTPS is encrypted and not as vulnerable to hackers and fraudsters. The best way to see that a site uses a secure protocol is to look for HTTPS in the URL. You can also look for the padlock icon on the webpage, an indication a site is more secure.
