Question: what is totp in aadhaar?
Answer: 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.
