WhatsApp has upgraded the iOS app, and it now supports biometric authentication. This update enables users to lock WhatsApp using Face ID and Touch ID. Even though this new functionality is not functional on a conversation to conversation basis, it does give an added layer of protection to the personal WhatsApp chats. Users of latest iPhone models like iPhone X, iPhone XS iPhone XS Max, shall be able to select Face ID unlock feature.
Users can select whether they wish biometric authentication just after they close the application, or after one minute, 15 minutes or 60 minutes. Turning on this newly added feature would help you bolster your security and keep your chats safe from intruding eyes. Here’s how you can toggle the feature on:
- Firstly, you need to update the app to the latest version called 2.19.20. You can do so by paying a visit to the Apple App Store.
- Now, open the Settings app.
- Tap on Account.
- Select Privacy from the list of options.
- Turn the toggle next to Screen Lock option to On position.
After enabling the new security update, the preview screen of Whatsapp shall not display anything. When it comes to privacy, the data regarding Face ID and Touch ID is encrypted in the iOS device, and WhatsApp shall not be able to access it since its management is done on phone-level access. Therefore, this feature is secure.
While the WhatsApp notifications shall be viewable on the phone, if the viewer wishes to see the message preview and users shall be able to send quick replies from their devices. Users will also be able to answer incoming Whatsapp calls without unlocking the app. The complete application shall remain inaccessible until the Touch ID or Face ID authentication is successfully completed.
After configuring the new unlock feature on the app, you shall have to quit the app and re-launch it. Thereafter, you will have to authenticate yourself if you want to access WhatsApp. In the event that the Touch ID or Face ID authentication is unsuccessful, one can sign in through a passcode.
