WhatsApp has introduced a new biometric authentication feature on its Android app, making the messaging platform more secure for millions of its users.
Dubbed as "fingerprint lock", it allows you to unlock the app only with your fingerprints, thereby blocking any unauthorized access.
Notably, the feature was introduced for iOS users in February.
Here's how to use the feature.

WhatsApp's fingerprint lock feature allows you to restrict app access, making it impossible for unauthorized users to gain entry to the app.
In simple words, your unique fingerprint now works like a password to unlock WhatsApp and it's definitely more convenient than entering long passwords.
The app uses the phone's built-in fingerprint reader to read the fingerprint and grant access upon successful verification.
