🔒 How to Enable Aadhaar Biometric Lock: Secure Your Digital Identity Today

In a world where digital frauds and identity theft are on the rise, safeguarding your personal information has never been more crucial. The Aadhaar Biometric Lock, introduced by the UIDAI (Unique Identification Authority of India), is a powerful tool to protect your fingerprints and iris scans from unauthorized access.

In this post, let’s explore how the Aadhaar Biometric Lock works, its benefits, and the easy steps to activate it using your smartphone.

🧠 What is Aadhaar Biometric Lock?

The Aadhaar Biometric Lock is a security feature that allows Aadhaar holders to lock or unlock their biometric data—fingerprints and iris scans—so that no one can use it for authentication unless explicitly permitted by you.

This ensures that even if someone has access to your Aadhaar number, they cannot misuse it for biometric-based services like banking, SIM card verification, or government schemes.
