Aadhaar Misuse: How to Check Authentication History, Lock Biometrics and Report Fraud

Aadhaar misuse is a growing worry for Indian residents, with reports of identity fraud, unauthorised SIM cards, and bank accounts opened using stolen Aadhaar details. The good news is that the Unique Identification Authority of India (UIDAI) provides free tools to detect and prevent misuse: you can check exactly where your Aadhaar has been used, lock your biometrics so that nobody can authenticate with your fingerprints or iris, and file complaints through dedicated channels. This guide explains how to check your Aadhaar authentication history, the steps to secure your number, and how to report misuse to UIDAI and the cybercrime authorities.

Step 1: Check Your Aadhaar Authentication History

UIDAI maintains a log of authentication requests made against your Aadhaar number, and you can review the recent record online. Log in to the myAadhaar portal with your Aadhaar number and the OTP sent to your registered mobile, and open the authentication history service. The history shows authentication requests over recent months, including the date and time of each request, the mode of authentication used, such as fingerprint, iris, OTP, or demographic, and the entity that requested it. Review the list for transactions you do not recognise. An authentication you never performed, especially a biometric one, is the clearest signal of attempted misuse. Note the details, take screenshots, and proceed to lock your biometrics and complain. Checking this history requires your mobile number to be registered with Aadhaar, so updating your mobile at an Aadhaar Seva Kendra is the essential first step if you have not done so.

Step 2: Lock Your Biometrics and Use VID or Masked Aadhaar

UIDAI allows every Aadhaar holder to lock their biometric data so that fingerprint and iris authentication is blocked until you temporarily unlock it. You can enable the biometric lock through the myAadhaar portal or the mAadhaar mobile app. Once locked, any attempt at biometric authentication fails, which neutralises the most damaging form of misuse. For everyday transactions, use a Virtual ID (VID), a temporary sixteen-digit number you can generate from UIDAI that can be used in place of your Aadhaar number, and prefer the masked Aadhaar download, which hides the first eight digits of your number, whenever you must share a copy. Never share the OTP received on your Aadhaar-linked mobile with anyone, since OTP-based authentication is the route fraudsters most commonly attempt after biometrics are locked.

Step 3: Report Misuse to UIDAI

If you find suspicious authentications or believe your Aadhaar has been misused, complain to UIDAI without delay. Call the toll-free helpline 1947, which operates in multiple languages, email help@uidai.gov.in, or file a complaint on the UIDAI website's grievance section with the details of the suspicious transaction. Keep your screenshots and notes from the authentication history as evidence. UIDAI can investigate authentication misuse by requesting entities and take action against erring agencies. Under the Aadhaar Act, 2016, impersonating another person or misusing their identity information is a criminal offence, so a complaint also creates the record needed for prosecution.

Step 4: Report Financial Fraud to Cybercrime Authorities

If money has been taken from your account, a SIM card issued, or a loan or account opened in your name, treat the matter as cybercrime in addition to an Aadhaar grievance. Call the national cybercrime helpline 1930 as soon as possible, because early reporting improves the chances of freezing the money trail, and file a detailed complaint on the National Cybercrime Reporting Portal at cybercrime.gov.in. Inform your bank in writing immediately so that liability for unauthorised transactions is limited, and consider filing an FIR at your local police station for serious cases. Also pull your credit report from the credit bureaus to check for loans you did not take, and raise disputes with the bureaus for any fraudulent accounts.

Preventive Habits That Stop Aadhaar Misuse

A few habits dramatically reduce risk. Keep your biometric lock enabled by default and unlock only when you need to authenticate. Share masked Aadhaar or VID instead of your full number, and write the purpose and date on any physical photocopy you hand over. Check your authentication history periodically, ensure your current mobile number is registered with UIDAI, and never respond to calls or messages asking for Aadhaar OTPs, since neither UIDAI nor any bank asks for them. When a service provider demands Aadhaar where another ID would do, remember that for most private services Aadhaar is one permissible document, not the only one.

Key Takeaways

To detect and stop Aadhaar misuse, check your authentication history on the myAadhaar portal, lock your biometrics through myAadhaar or the mAadhaar app, and use VID or masked Aadhaar when sharing identity details. Report suspicious activity to UIDAI on 1947, help@uidai.gov.in, or its online grievance portal, and report any financial fraud immediately on 1930 and cybercrime.gov.in, alongside written notice to your bank. Misuse of identity information is an offence under the Aadhaar Act, 2016. With the biometric lock on and your mobile number current in UIDAI records, your Aadhaar is substantially harder to abuse.
