Now you can feel a little more secure, as Google just announced that Gmail will be all encrypted all the time. Every single email you send or receive will use an encrypted HTTPS connection, regardless of device. It'll even be sure in public Wi-Fi too.

Gmail has offered HTTPS encryption since it launched but now your messages aren't only encrypted between Gmail and your computer, they're also encrypted as they travel around Google's data centers. The company also uses top of the line encryption technology so you can feel even safer.
