Google employs TLS (standard encryption) to make your emails reasonably secure while in transit. (The more secure S/MIME encryption is also available, but it is only accessible to businesses and educational institutions.) There are, however, alternative methods to keep your personal data protected, one of which is to use Google’s confidential mode.
In 2018, Google debuted Gmail’s secret mode. The option enables users to send communications that may expire and prohibits receivers from copying, forwarding, or downloading their contents.
You may use confidential mode on a desktop or via the Gmail app on a mobile device, but you must activate it each time you send a message. Here’s how to go about it.
Method 1. Using the web client
Step 1. Open the Gmail portal and sign in using the correct credentials.
Step 2. Click on the ‘Compose’ button to start a new email.
