What is TOTP in Aadhar & How to Generate TOTP: A Complete Guide

In India, the two utmost vital documents that are considered as a proof of identity are Voter Identity Card and Aadhaar Card. The Voter Identity Card gets issued to you by the Election Commission of India to citizens of India who are above 18 years of age and therefore allows you to cast your vote in many elections held in your city, State and the country. The Election Commission of India issues Voter Identity Cards to persons who enrol themselves in the polling list. And therefore, your Voter Identity Card is treated to be an official and legal identity proof.

On the contrary, Aadhaar Card is a unique number, issued to Indian citizens with the children as well as the infants, on the basis of their biometric data and demographic information.

What is an Aadhaar Card?

Aadhaar Card is a unique identity card issued to the Indian citizen by the Unique Identification Authority of India- UIDAI. The card has an arbitrary grouping of 12 numerical figures that are unique for each Aadhaar cardholder. This 12-digit number is known as the Aadhaar card number and is used to identify individuals. The card comprises the demographic and biometric data of the person and therefore is used mainly for authentication. Aadhaar cards are issued free of charge and people can voluntarily apply to enrol themselves. Its uniqueness helps to remove duplicates and incorrect identities and is used as a key enabler to roll out plentiful Government welfare arrangements for better distribution of service. Globally this is the first step in India of its kind, in which a digital and online Id is available which is free at a huge scale to the residents of India.

While using the Aadhaar card, we often come across two terms which are OTP and TOTP. While most of us know about the OTP as One- Time Password, many of us are not aware of the TOTP. Here we will discuss TOTP in detail, but before that let us understand what is TOTP in aadhaar.
