WhatsApp on April 13, announced three additional security features in order to provide extra layers of privacy and more control over messages.
Here are the new WhatsApp features.
Account Protect:
While switching to a new device, WhatsApp may send an alert notification to the old device to ensure that it isn't an unauthorized attempt to move your account to another device.
Device Verification:
This feature adds an extra step behind the scenes that authenticate and protect the account if a device is somehow compromised. This check has been added to prevent mobile device malware.
Automatic Security Codes:
WhatsApp is building a new, private, and automated way to verify encryption keys, which will make it easier to confirm that the message is received by the intended recipient.
