Gmail now always uses an encrypted HTTPS connection when you check or send email and it cannot be turned off.

“No one can listen in on your messages as they go back and forth between you and Gmail’s servers,” the firm said in a press release.

Your email is important to you and making sure it stays safe and always available is important to us, said Google.

As you go about your day reading, writing and checking messages, there are tonnes of security measures running behind the scenes to keep your email safe, secure, and there whenever you need it, said the firm officials.

The effort is in the wake of the revelations made last year when National Security Agency (NSA) whistle-blower Edward Snowden told the world that the NSA had access to Google's servers.

According to Google, new change means that no one can listen in on your messages no matter if you are using public WiFi or logging in from your computer, phone or tablet..
