With about 1.24 billion AADHAAR cards issued to Indians and with about 30 billion authentications done through this document, AADHAAR has become one of the most significant document with everything connected to the Government, utilities and fintech companies.  

By making KYC process paperless, AADHAAR verification was successful in reducing the new customer onbaording cost by upto 85% by various mobile wallets, cellphone operators, insurance cos. and mutual funds. But with this came the controversy of safeguarding your personal information. Linking AADHAAR number with everything, everyone's personal information was going in public domain. 

So [UIDAI](https://www.uidai.gov.in/) introduced the option of locking and unlocking of your personal information as per your preference.

You can lock and unlock your AADHAAR biometrics by visiting the [UADAI website here](https://resident.uidai.gov.in/biometric-lock). It can also be done through [mAadhaar mobile app](https://play.google.com/store/apps/details?id=in.gov.uidai.mAadhaarPlus&hl=en_IN) or by sending a SMS to 1947 from your AADHAAR registered mobile number. You will need to generate a virual PIN to enable or disable the data authentication feature. The process is fairly easy and you can check details by visiting the above links.

Once biometric lock is implemented, your AADHAAR number and the data associated with it will not be possible to use for any authentication purpose.
