WhatsApp is now presenting fingerprint unlock to all Android users after testing the feature on beta users for a little while. The company has presented biometric security to Android at least 8 months after similar options offered on the iPhone. The Fingerprint Lock security feature is available in version 2.19.222 of the Android WhatsApp app. It offers Android users a security option that is more in line with what is available in the iOS version of the app. It is important that iPhone users already have Touch ID and Face ID support.
Now WhatsApp said, “Today we’re introducing similar authentication, allowing you to unlock the app with your fingerprint, on supported Android phones”. Fingerprints are the only security options available now. WhatsApp has not yet enabled face unlocking for Android users. The company didn’t mention that it will be offered in the near future. The new feature prevents other people from accessing WhatsApp and reading your messages after enabled.
You will find only a way to get into the app is to scan a registered finger. The description of the setting within the app says, “When enabled, you’ll need to use fingerprint to open WhatsApp. You’ll still be able to answer calls if WhatsApp is locked”. People can enable Fingerprint lock, just go to Settings > Account > Privacy > Fingerprint lock. You will then be able to Turn on Unlock with fingerprint and confirm your fingerprint. Users can also select how long WhatsApp should wait before it locks, either immediately or after one minute, or after 30 minutes.
