OTP or One-Time Pin is a mode of authentication offered by the UIDAI. Under one-time PIN-based authentication, an OTP with a limited-period validity is sent to the mobile number and/or e-mail address of the Aadhaar number holder registered with Aadhaar. "The Aadhaar number holder shall provide this OTP along with his Aadhaar number during authentication and the same shall be matched with the OTP generated by the Authority," according to the UIDAI website - uidai.gov.in. Besides OTP, the UIDAI also offers biometric-based authentication.
But is it secure to link Aadhaar card with mobile SIM? The UIDAI has addressed this on microblogging site Twitter.
Here's what the UIDAI said on Aadhaar-SIM linking:
