A cryptography and security researcher at the University of California has discovered a loop hole within WhatsApp that allows Facebook to view user's messages, as a result of the end-to-end encryption protocol.
If this makes you feel uneasy and you think it's now time to move away from the messaging service, here's some alternatives for you to consider.
Signal first appeared back in 2014. It's the messaging app used and championed by Edward Snowden. It provides comprehensive security, end-to-end encryption with PFS, no metadata storage and all details of contacts are stored in a protected system.
It's possible to make phone calls or create group chats within Signal, but the interface is not quite as polished as WhatsApp.
This app is not quite as well known as Signal, but offers a very similar and secure service. The app had the backing of Skype co-founder Janus Friis and has a nicer user interface in comparison to Signal. It's possible to send text messages, voice and video notes and it's even possible to screen share.
