WhatsApp has two billion users, it has said in a new announcement.

It means that more than a quarter of the world’s population are on the chat app.

WhatsApp used the announcement to stress its commitment to security – a position that has led to criticism from lawmakers and politicians in some countries.

“Strong encryption is a necessity in modern life,” it wrote in a blog post. “We will not compromise on security because that would make people less safe.
“For even more protection, we work with top security experts, employ industry leading technology to stop misuse as well as provide controls and ways to report issues — without sacrificing privacy.”
