Bank Emptied Without OTP? Lock Your Aadhaar Biometrics Now

19 May, 2026

How to lock Aadhaar biometrics online on UIDAI portal to prevent AePS fingerprint cloning fraud

🛑 They Don't Need Your OTP. They Just Need Your Fingerprint.

You wake up to a series of SMS alerts showing multiple ₹10,000 cash withdrawals from your savings account. You never received a warning, you never clicked a phishing link, and you certainly never shared an OTP. How did your money vanish? It is a massive vulnerability in the banking system called AePS fraud. Scammers are cloning your physical fingerprints from public records to drain your account silently. If you haven't locked your Aadhaar biometrics yet, your entire life savings are exposed.

The Aadhaar Enabled Payment System (AePS) was designed for rural inclusion, allowing people to withdraw cash from micro-ATMs using just their Aadhaar number and a fingerprint scanner.

But the system has a fatal flaw: fingerprints are easy to steal. Every time you register a property, sign a lease agreement at the sub-registrar office, or submit documents for a new vehicle, your thumbprint is recorded. Scammers acquire these records, use a 3D printer and silicone to clone your thumb, and walk away with your cash.

1. The Only Defense: UIDAI Biometric Lock

Banks cannot stop AePS fraud because the transaction looks 100% legitimate to their servers—it has your "authentic" biometric signature. The only way to stop this is to sever the connection at the source.

Your Immediate Action: You must digitally lock your Aadhaar biometrics. When locked, any attempt to authenticate your fingerprint or iris scan—even by you—will instantly result in a "Verification Failed" error. The scammer's cloned fingerprint becomes completely useless.

2. Step-by-Step: How to Lock Your Aadhaar

Locking your biometrics is free, takes less than two minutes, and can be temporarily unlocked anytime you actually need it (like buying a new SIM card).

Method	Action Required
Via mAadhaar App	Download the official UIDAI mAadhaar app. Register your profile using the OTP sent to your linked mobile. Tap on "My Aadhaar" > "Biometric Lock" > Enable.
Via UIDAI Portal	Go to myaadhaar.uidai.gov.in. Log in with your Aadhaar number and OTP. Click on the "Lock/Unlock Biometrics" tile. Confirm the warning and hit Submit.

Pro Tip: When you legitimately need to use your fingerprint, use the portal to select "Unlock Biometrics." It will temporarily unlock for 10 minutes and then automatically lock itself again, keeping you permanently secure.

3. What to Do If You Are Already a Victim?

If you check your statement and realize you have already been hit by unauthorized AePS withdrawals, you are protected by a specific Reserve Bank of India (RBI) circular.

The 3-Day Rule: Under RBI guidelines on "Customer Liability in Unauthorized Electronic Banking Transactions," if you report the fraud to your bank within 3 working days, your liability is ZERO. The bank is legally required to refund the entire amount, even if the scammer is never caught.
Immediately call the 1930 Cyber Fraud Helpline to log the incident and get an acknowledgment number.
Visit your home bank branch, submit a written complaint citing the RBI circular, and demand the reversal of the AePS debit.
