These websites are encrypted with the SSL / TLS protocol to secure transmitted data. Typically you would expect to see the padlock icon on websites where sensitive data may be transmitted, such as a banking website or online shopping site. In most browsers, users can click the padlock to learn additional information about the secure connection, including any permissions you have previously granted, information about the website and verification, the number of times you have visited the site, stored cookies, saved password and more.
