WhatsApp update finally brings long-awaited security feature

WhatsApp has improved the security for its app by introducing an extra layer of protection for privacy-conscious users. The latest update for the popular messaging app allows people to restrict access using biometric technology. Version 2.19.20 of WhatsApp will include the new security feature for users of the iOS app, meaning iPhone owners can restrict access to the app using either Face ID facial recognition or Touch ID fingerprint security. The feature was first reported last month by the WeBetaInfo website, who spotted the update in an unreleased version of the app. Its roll out on the iOS app was then spotted by unofficial Apple news site 9to5Mac.
