    WhatsApp: how to activate fingerprint lock

    WhatsApp supports fingerprint lock on Android, just like on iPhone. Previously, to protect your conversations, it was possible to set up a six-digit code, or even two-factor authentication. Simpler and faster, this new process makes it possible to reinforce the security of the application, while preventing prying eyes from falling on your conversations.

    Indeed, by activating the fingerprint lock, you can also choose to hide the content of notifications. This prevents anyone with access to your smartphone, even for a few seconds, from being able to see an excerpt of messages received in the notification bar or on the lock screen.

    Incoming calls, however, are not blocked. The feature has already been known to WhatsApp users on iPhone for many months. The latter can, on compatible models, even use Face ID to make unlocking even faster and more reliable. Concretely, it is possible to choose to request the imprint immediately, after 1 minute or after 30 minutes. An option allows to show or hide whatsapp notification content when locked.

    Before you start, be aware that you must first have configured one or more fingerprints in Android's security settings. WhatsApp indeed uses system-wide enabled biometric options. Then, to activate fingerprint locking/unlocking:

    • 1. Open WhatsApp
    • 2. Tap the three dots in the upper right corner. Go to the Settings > Accounts > Privacy
    • 3. Choose the time beyond which the smartphone will be locked
    • 4. Also activate (as desired) the option to hide the content of notifications
