Aadhaar Lock & Unlock Feature: How to Secure Your Aadhaar Number Online

With the growing use of Aadhaar for banking, government schemes, and digital services, Aadhaar security has become a major concern for Indian citizens. To address this, the Unique Identification Authority of India (UIDAI) introduced the Aadhaar Lock & Unlock feature, allowing individuals to control when their Aadhaar number can be used for authentication.

This guide explains what the Aadhaar Lock & Unlock feature is, why it is important, and how to lock or unlock Aadhaar online step by step.

What Is Aadhaar Lock & Unlock Feature?

The Aadhaar Lock & Unlock feature is an official UIDAI service that lets Aadhaar holders temporarily disable Aadhaar-based authentication. When Aadhaar is locked, it cannot be used for biometric, OTP, or demographic verification.

Once unlocked, Aadhaar works normally again for authentication purposes.

This feature is designed to protect Aadhaar from misuse and unauthorized access.

Your biometric and personal data remain protected from unauthorized verification attempts.

📄 Useful in Case of Aadhaar Loss

If your Aadhaar card is lost or stolen, locking Aadhaar immediately safeguards your identity.
