Facebook-owned instant messaging platform, WhatsApp had recently launched new authentication features to add an extra layer of security on the app. The new feature rolled out for iOS users had brought Face ID and Touch ID authentication to WhatsApp. But, the app has reportedly been hit by a bug which disables these features and allows users to access WhatsApp even with the new security option being enabled. This puts your WhatsApp data at risk. The bug was first spotted by a Reddit user named de_X_ter who highlighted that if WhatsApp Face ID, Touch ID authentication feature has 1 minute, 15 minutes or 1 hour for the kick-in time, then the bug allows anyone to go past the security layer while using the WhatsApp share option on any other third-party application.
This means that in an ideal case, if you are using iOS Share Sheet, it should usually trigger Touch ID or Face ID authentication. But, because of this bug, ut doesn't happen. It also allows users to open the iOS Share screen without the need of Touch ID or Face ID. Even if the app asks for authentication, the users can simply tap the back button and continue the operation while bypassing the Face ID, Touch ID authentication.
What should users do?
It is still unclear if the problem is with WhatsApp or with iOS devices. So, the only way to tackle this problem right now is by setting the kick-in time for the WhatsApp Face ID, Touch ID authentication feature. This can be done heading to WhatsApp > Account > Privacy > Screen Lock.
