Bug detected in WhatsApp’s biometric feature for iOS users

According to reports published by the media, a Reddit user has spotted the bug in WhatsApp which is allowing people to bypass the Touch ID or face lock feature of the messaging app.

Recently, messaging service WhatsApp had launched the biometric security lock feature for iOS users which was aimed at adding an extra layer of protection over the app so that no one can read private chats of WhatsApp users even if their phones were left unlocked or unattended for a long time.

But, if a Reddit user is to be believed, a new bug has been discovered in the biometric feature of the iOS app which is letting anyone access chats of other Whatsapp users who have been protecting them with a Touch ID or a Face ID.

According to reports published by the media, a Reddit user has spotted the bug in WhatsApp which is allowing people to bypass the Touch ID or face lock feature of the messaging app.

The user has also shared a screenshot which suggests that the bug gets activated the moment a person tries to access the WhatsApp share extension. This particular extension allows users to share anything on their phones via WhatsApp.

According to the user who has brought out the issue, a person first needs to share something via iOS Share Sheet on his or her phone in order to bypass the biometric authentication of WhatsApp.

To make the authentication feature effective, the messaging app provides users with three options which are ‘Immediately’, ‘After 1 minute’, ‘After 15 minutes’, and ‘After 1 hour’.

If a user selects the ‘immediately’ option, the bug gets instantly activated. It is important to note that the bug has only been detected in the iOS version of the messaging app since only the iOS version has the authentication feature at present.

Under the biometric feature of WhatsApp, iOS users who use iPhone X or family models will receive a Face ID lock, while users who have older models of the iPhone will be given the option of the fingerprint lock.

For the uninitiated, the biometric feature can be activated using the following steps. Go to the WhatsApp settings on your iPhone and then go to the Privacy section under the Account option.

Click on the screen lock option and enable the Touch ID or Face ID depending on your iPhone model. Then select any one of the four options ‘immediately’, ‘after one minute’, ‘after 15 minutes’, and ‘after one hour’.

Users should also keep in mind that the authentication feature can only protect your chats from unknown access in case your iPhone is left unattended. It will not hide the chats from your notification panel for which you will have to change your phone settings.
