Sending private messages via email is risky – the recipient could forward it to your arch nemesis or keep it as blackmail.
Luckily, Google has introduced “confidential mode” to help protect your messages.
- Set an expiration date for messages
- Revoke access to messages any time (even before their expiration date)
- Require a passcode to open messages
Confidential mode also prevents recipients from forwarding, copying, printing, and downloading your messages.
It’s not perfect, of course; Google notes that confidential mode “doesn't prevent recipients from taking screenshots or photos of your messages or attachments” – so if the recipient is untrustworthy, it’s probably best to avoid emailing them entirely.
Still, Gmail’s confidential mode helps you protect sensitive information from unauthorized access without the hassle of encryption.
