Aadhar is one of the most important documents that one has in India at the moment. It acts as an address proof and comes in handy when applying for many other documents. Aadhar contains a person’s biometric data as well but that data is kept locked up to main privacy and confidentiality. UIDAI now allows the Aadhar card holders to temporarily lock their Aadhar biometric data and when locked, the Aadhar holders will be unable to use this data for authentication. Locking and Unlocking of this Aadhar Biometric Data will help in preventing any sort of misuse.

According to the UIDAI Website, “UIDAI has introduced a feature to lock and unlock your Aadhar Number. After locking your Aadhar Number, Authentication cannot be performed using your Aadhar Number. In that case, you may use your Virtual ID to perform Authentication.”

Step 4- Click on the checkbox that says, ‘I Understand that after biometric lock enables, I will not perform biometric authentication until I unlock Biometrics’ and then click on Lock/Unlock Option.
