Aadhaar Lock/Unlock: Protect Your Identity from Misuse

Aadhaar is a 12-digit unique identification number issued by the Indian government to every resident of India. It stores your demographic and biometric details and is widely used for identity verification across various services. While Aadhaar provides ease and convenience, ensuring its security is equally important to avoid misuse or fraud—which is why the Aadhaar Lock/Unlock feature plays a vital role in protecting your identity.

To enhance security and protect your personal information, the Unique Identification Authority of India (UIDAI) provides a useful feature known as Aadhaar Lock/Unlock. In this blog, we will explain what it means, how to unlock Aadhaar online, and what steps to take if you forget your Virtual ID (VID) after locking it.

What Is Aadhaar Lock/Unlock and How Does It Work?

Aadhaar Lock is a powerful security feature that allows Aadhaar holders to temporarily disable their Aadhaar number from being used for any authentication or KYC (Know Your Customer) process. Once locked, no one can use your Aadhaar number, Virtual ID (VID), or biometric/demographic details, making it highly effective in preventing misuse, identity theft, or fraud.

When you need to use Aadhaar again, simply use the Aadhaar Unlock feature. This reactivates your UID for all authentication services, allowing you to proceed with UIDAI Aadhaar unlock through secure channels.

This control ensures that only you decide when and how your Aadhaar card is used, significantly improving privacy and security.

How Can Aadhaar Number Holders Lock UID?

To lock your Aadhaar number, you first need to generate a Virtual ID (VID), a temporary 16-digit random number mapped to your Aadhaar that acts as an alternative for authentication without sharing your actual Aadhaar number.

Steps to Lock Aadhaar:

Generate Virtual ID (VID) (if not already done)
- Visit the UIDAI website myaadhaar.uidai.gov.in.
- Use the “Generate Virtual ID” service by entering your Aadhaar number and OTP received on your registered mobile number.
- To generate your Virtual ID (VID) – GVID <Last 4 digits of your Aadhaar Number> and send it via SMS to 1947 from your registered mobile number.

How to Unlock Aadhaar Card PDF

If you’ve previously downloaded an Aadhaar PDF (which is password protected), you’ll need the correct password to open it.

Password format: First four letters of your name in capital letters + birth year in YYYY format.
- For example, if your name is “RAHUL KUMAR” and your birth year is 1990, your Aadhaar PDF password will be: RAHU1990.

You can open the Aadhaar PDF with this password to view or print your Aadhaar details offline.
