WhatsApp is constantly adding new features to its platform, making the messaging app more functional and secure for billions of users.
In a recent development, the company introduced a new biometric authentication feature on its Android app, allowing you to block unauthorized users from accessing the app. The feature was introduced for iOS users in February.
First, here's how the fingerprint lock feature works
WhatsApp's fingerprint lock feature allows users to encrypt app access, letting them (or other authorized users) gain entry to the app only after secure biometric authentication. In simple words, your fingerprint now works like a password to unlock WhatsApp.
The app uses the phone's built-in fingerprint reader (Touch ID/Face ID on iOS devices) to read the fingerprint and grant access only upon successful verification.
