WhatsApp announced another authentication level for WhatsApp users using Android devices: Fingerprint Lock.
WhatsApp rolled out Touch ID and Face ID authentication for iPhone users earlier this year, and is now introducing a similar feature to Android users, allowing them to unlock the app with their fingerprint. The new fingerprint lock feature is important as it provides “an extra layer of security” for users on the app.
Fingerprint lock is available on supported Android phones at the moment, and in order to enable it, users need to visit Settings > Account > Privacy > Fingerprint lock and toggle the “Unlock with fingerprint” option. Finally, they will also need to confirm their fingerprint, as is the usual process of setting up a fingerprint login.
Users can also choose to automatically lock their app immediately, after 1 minute, or after 30 minutes.
