WhatsApp’s fingerprint look ensures added privacy and security to users. The platform already has end-to-end encryption, it also offers almost all necessary features to keep its users happy and secure. However, it did not have any other option to keep the app safe from unauthorised access. The company has now addressed this issue on a broader level. For iPhone users, WhatsApp already has an option to use TouchID as well as FaceID to secure the WhatsApp chats.
Android users of WhatsApp now get an option to use the fingerprint lock authentication. This feature will allow users to secure their app with their fingerprint data. With this introduction, you no longer have to use third party app lockers to secure your WhatsApp chats.
WhatsApp users can choose to let the app ask for fingerprint authentication as soon as the app is closed. They can even set a specific time limit to unlock the app. The app offers an option to hide the message content in notifications for enhanced security. Once you enable the fingerprint authentication, the app will ask for fingerprint every time you open the app. Once the verification is done, users can access the chats and message.
The feature works well with conventional fingerprint sensors as well as in-display fingerprint sensors. The face unlock option is not supported on Android as of now. The modern smartphones without fingerprint sensor such as Pixel 4 are out of luck.
If your phone has a fingerprint sensor, here’s how you can setup the authentication for WhatsApp:
- Update your app to the latest v2.19.308 from Play Store.
- Open WhatsApp and go to settings.
- Select “Account” option and tap on “Privacy”
- Scroll down to the newly added “Fingerprint lock” feature.
- Enable the “Unlock with Fingerprint” option and confirm your fingerprint.
- You will find timer customisation options to automatically manage the app lock.
