Ironically, Facebook’s WhatsApp may now be one of the most secure messaging apps.
WhatsApp will now encrypt your backups, along with the existing end-to-end encryption it uses for sending messages. This means that there’s no way to access your messages without physical access to your device.
The encryption applies to the backups stored on Apple’s or Google’s servers, which means that your iCloud backup is safe, for example, even if Apple is compelled to hand over your otherwise unencrypted backups to the police. So, does this make WhatsApp the safest messaging service?
