Google uses TLS encryption to keep contents of an email safe while it is in transit. This encryption prevents hackers from snooping in users’ conversations while they are travelling from sender to receiver. However, sometimes having encryption isn’t enough to prevent confidential details in an email from getting leaked. There is always the risk that the receiver of the email containing confidential details can accidentally forward the mail to someone it was not intended for. So, for times like these, Gmail has a feature called Confidentiality Mode that is aimed to prevent such leaks. Also Read - How to download and set up Google Duo on Android TV: A step-by-step guide
With Confidential Mode, Gmail users can set an expiration date for messages or revoke access at any time. Recipients of the confidential message cannot forward, copy, print, or download the message or attachments in an email sent with confidential mode on. However, they can capture a screenshot of photos or attachments in the email. Also Read - YouTube will now let creators reply on fans' comment via Shorts
