WhatsApp for Android supports fingerprint lock feature
WhatsApp today announced the opening of a new layer of security for Android users, which can be used to unlock the WhatsApp application via fingerprints. In fact, this feature has been enabled on the iPhone before, and users can unlock it with Face ID or Touch ID. Similar locking features have appeared in many similar applications, including the popular encrypted messaging application Signal. The instant messaging application has largely replaced SMS text messages and emails, becoming the primary means of communication for contemporary users.

“Earlier this year, we rolled out Touch ID and Face ID for iPhone to provide an extra layer of security for WhatsApp users. Today we’re introducing similar authentication, allowing you to unlock the app with your fingerprint, on supported Android phones. To enable it, tap Settings > Account > Privacy > Fingerprint lock. Turn on Unlock with fingerprint, and confirm your fingerprint.”
