Less than a month after WhatsApp added a new security feature to its iOS app, users have found a vulnerability. The Facebook-owned chat app added a handy ‘lock’ ability to its iOS app that requires Touch ID or Face ID to unlock the app and view chats.

In a nutshell, WhatsApp’s latest bug make the secondary biometric authentication step of the Touch ID or Face ID useless when someone tries to access the app via a sharing extension as reported by Reuters.
WhatsApp has acknowledged the issue and promised to release a fix soon. The company also recommended users to change the screen lock option to “immediately” to avoid the bug.
