The virtual aadhaar (mAadhaar) card allows you to make changes in your profile via a TOTP. The time-based one-time password or TOTP is generated by an algorithm and is valid only for 30 seconds. The TOTP is an 8-digit long numeric string. The TOTP is a way to circumvent the traditional SMS based OTP. The most crucial weakness that is addressed by the temporary OTPs is that user will not be dependent on mobile network for the sms delivery. TOTP is an example of a hash-based message authentication code.
The TOTP is generated in mobile application mAadhaar. Time-based one-time passwords are commonly used for two-factor authentication and have seen growing adoption by cloud application providers.
Besides the TOTP, there are a host of other features of mAadhaar. These include biometric locking or unlocking of biometric details. This is allowed to enable the biometric authentication by locking biometrics data.
