Gmail's new self-destructing emails are now rolling out to mobile devices

Tuesday, 21 Aug, 2018

Confidential Mode is now available on the iOS and Android Gmail apps. Still, it's always nice to see more security features for popular apps like Gmail.

How to send mail using Confidential Mode in Gmail?

One new feature just went live as Google has turned on their confidential mode for Gmail.

The feature is live now in Gmail, so you can check it out.

Tap the hamburger menu in the top right corner. That is a very secure way to view an email, and you can definitely send sensitive and confidential material to others. Find your email set to self-destruct in the Sent folder, open it, and tap "Remove Access".

Now you can set the passcode and only when the recipient enters the code that he recieves in an SMS on their phone can they open and check the email. Lastly, users using Gmail with a work or school account will need to contact their administrator in order to use confidential mode.

Google announced today that Gmail's confidential mode has come to mobile devices.

For the time being, SMS-based passcodes are only available for users in North America, Europe, India, Japan and South America.

Those sound pretty excellent security features, sure, but someone who needs that amount of protection probably won't use Gmail in the first place. Additionally, recipients can't forward, copy, print or download these emails.

It is worth noting once an email is sent any self-destruct date that was chosen can not be altered.

The company's support page describes confidential mode in more detail. This will now be the norm for all confidential emails you send.

Confidential mode could help prevent information leaks, but Google has a few caveats. In a recent review, EFF points out that the message isn't encrypted from end-to-end, so Google could read the contents. That means that Google will have access to personal data i.e. the phone number of the recipient, even without his permission.
