How to Lock & Unlock Biometrics in Aadhaar: Easy Steps 2026

By

Aadhaar is not just a unique 12-digit number that residents of India receive, but an essential identity proof issued by the Aadhaar UIDAI. It is linked to an individual’s biometric data — fingerprints, iris scans, and demographic details such as name, date of birth, and address. The system is central to government and private sector initiatives aimed at offering better services and benefits to the residents of India.

The Aadhaar Card is used for various purposes, including opening bank accounts, applying for government subsidies, and verifying identity at different service points. However, with such sensitive data stored, it’s crucial to take every possible measure to protect it from misuse.

One of the primary security features that UIDAI provides to protect this information is the ability to Lock & Unlock Biometrics in Aadhaar. This feature allows individuals to control when and where their biometric details can be used for authentication. This article will guide you through the process of Locking & Unlocking Biometrics in Aadhaar to ensure you have full control over your digital identity.

The process is simple, and users can lock & unlock biometrics in Aadhaar as needed through either the UIDAI website or the mAadhaar mobile app. This temporary disabling of biometric authentication is a preventive measure to protect your identity, ensuring that no unauthorized person can misuse your Aadhaar for services.
