HTTPS, the lock icon in the address bar, an encrypted website connection—it’s known as many things. While it was once reserved primarily for passwords and other sensitive data, the entire web is gradually leaving HTTP behind and switching to HTTPS.
The “S” in HTTPS stands for “Secure”. It’s the secure version of the standard “hypertext transfer protocol” your web browser uses when communicating with websites.
