Gmail now lets you send self-destructing 'confidential mode' emails from your phone
Found on ZD Net on Monday, 20 August 2018
Google promotes the Gmail feature as a way to protect sensitive information by allowing users to set an expiration date for individual messages or revoke access to messages already sent.
The feature also prevents recipients from forwarding, copying, printing or downloading its content and allows users to require recipients to enter a one-time code sent via SMS to view the email.
Its main criticism is that Gmail isn't an end-to-end encrypted service, so Google could read your email.
Like that's going to work. As soon as emails are sent to a 2rd party, and/or downloaded with a real email client, it will stay there forever. Gmail is just trying to promote a "feature" nobody needs or wants.
