Already in July, Google had introduced a new design for the web version of Gmail. The rollout included new features in addition to the visual changes, one of which is the Confidential mode. This new privacy-centric feature has finally arrived in the mobile app version of the service, and here's what you need to know.
Confidential mode is basically a self-destruction of emails. In this way, Google can meet the needs of customers who do business with Gmail and transfer private information. This mode provides additional protection and makes sending private data more secure than sending a standard e-mail. However, it is not a perfect solution.
What is a Confidential Mode
Confidential Mode is a new feature that can be activated when sending an e-mail. After activation, you can send an e-mail to a recipient and prevent certain features from being used. In particular, emails sent in this mode can not be forwarded, copied, printed or downloaded. This restriction also applies to all attachments included in the message.
In addition, you must set an expiration date for the message. After expiration, the message is no longer accessible to the recipient. The recipient must also enter a passcode generated by Google and sent via text message or e-mail. Gmail accounts can only receive text messages, while non-Gmail accounts can receive the password code based on the option you choose.
To test the feature, create a new message in your Gmail app either by using the "Plus" button or by replying to a previous message. Tap the three dots in the top right corner and select "Confidential Mode" from the menu.
This new page contains all the configurable options for sending messages in this mode. You can adjust the expiration date and customize the method you want to use to send the passcode.
For the expiration date, you can specify that the email expire after one day, one week, one month, three months. or five years. I'm not sure why Google chose days off, but these are your only options. This date does not depend on when the recipient receives the message or when it opens the message (so be careful with short expiration dates).
Select "Default" for the passcode to send it without a password (if the recipient uses a Gmail account) Email the passcode (for non-Gmail e-mail addresses). Select SMS to send the code via SMS. Select "Save" above to return to the message. After selecting the appropriate Send Message button, Gmail prompts you to enter the phone number if you select SMS and this email address in your contacts does not have a phone number associated with it. Once added, the message is sent.
