Aadhaar Biometric Lock/Unlock 2026: Protect Your Identity from Misuse
Aadhaar Biometric Lock/Unlock 2026 is a security feature provided by the Unique Identification Authority of India (UIDAI) that allows Aadhaar holders to lock and unlock their biometric information whenever required. This feature helps protect fingerprints and iris scan data from unauthorized use, reducing the risk of identity theft and biometric fraud.
Moreover, once your Aadhaar biometrics are locked, no one can use your fingerprints or iris details for authentication until you unlock them. Therefore, locking your biometrics is highly recommended, especially if you do not frequently use biometric authentication for banking, government services, or e-KYC.

The Aadhaar Biometric Lock/Unlock service enables residents to temporarily disable or enable biometric authentication linked to their Aadhaar number.
When biometrics are locked:
- Fingerprint authentication is disabled.
- Iris authentication is disabled.
- Face authentication remains available where supported.
- Unauthorized biometric access is prevented.
Furthermore, the service can be activated or deactivated instantly through the official UIDAI portal.
