Google has announced an improved security feature in Gmail that is security of incoming emails by alerting users if they are sending messages over an insecure connection
Google was already using Transport Layer Security (TLS) cryptography and now firm has taken the extra step of using visible icons to warn of potential danger
Google Increases Gmail Security by Adding a Warning to Unencrypted Emails
John Rae-Grant, product manager at Google in the announcement said:
“It takes at least two people to send and receive an email, so it’s really important that other services take similar measures to protect your messages – not just Gmail. Unfortunately, not all email services do,”
Now, if you receive a message from someone whose email service doesn’t support TLS encryption, you’ll see a broken lock icon in the message. Additionally, if you receive a message that can’t be authenticated, you’ll see a question mark in place of the sender’s profile photo, corporate logo, or avatar.
“Not all affected email will necessarily be dangerous. But we encourage you to be extra careful about replying to, or clicking on links in messages that you’re not sure about. And with these updates, you’ll have the tools to make these kinds of decisions,”
