ecure) The protocol used to access a secure Web server. When https://
is used as the prefix of a Web address rather than http://
, the session is managed by a security protocol such as TLS, and the transmission is encrypted to and from the Web server.
Increasingly, all websites use HTTPS; for example, in 2015, Wikipedia switched to HTTPS. For details about the HTTP protocol, see HTTP
. To learn about the security protocol, see TLS
and security protocol

and HTTPS Everywhere
The Closed Lock
A closed padlock indicates the website is accessed via HTTPS, which almost every site is these days. In this example, the complete address is https://www.nytimes.com.
A Lot of Secure Traffic
Today, way more HTTPS packets traverse the Internet than regular HTTP; witness this metric from a router in a home.
