Are you a Gmail user? If yes, there is a happy news waiting to be heard. Google now offers its Gmail users a way to secure their emails.
You can access Gmail through HTTPS (Hypertext transfer protocol secure) rather than the unsecured HTTP which you were using till now. To quote from the official Google Blog, “We care about your security today just as much as we did when we launched, which is why we're constantly working on improvements like the recently launched last account activity and remote sign-out. Today, we're making it even easier for you to use HTTPS to protect your mail every time you access it. We've added an option to Settings to always use HTTPS.”
Even when you manually forget to type ‘s’ in http://mail.google.com, it will automatically turn to https. What is noteworthy is that your session will remain encrypted for the entire session and not just for log-in.
