UIDAI’s mAadhaar App Updated With Dynamic OTP, Know Its Applications and How to Use It

A new feature has been added to the mAadhaar app, an initiative by The Unique Identification Authority of India (UIDAI), an agency that administers Aadhaar. The feature called time-based one-time password (TOTP), will help to ease the authentication using the app. The feature will do away with the need to wait for the OTP to arrive, especially in slow network areas where most transactions fail due to delay in receiving the OTP.

Ajay Bhushan Pandey, CEO, UIDAI said “TOTP has been configured in the Self Service Update Portal (SSUP) and eAadhaar download. In future, all OTP based Aadhaar authentication applications will be migrated to TOTP based Aadhaar authentication. TOTP addresses OTP related shortcomings like residents dependency on mobile network for SMS delivery, etc. The TOTP is unique for every user, and the only requirement is that the user’s smartphone should be in sync with the Indian time-zone.”


The app was launched in July this year. And now the download count has reached over a million. After downloading the app on your Android smartphone, you’ll first have to create a profile password. In the next step, you’ll have to import your Aadhaar details – enter the 12-digit Aadhaar number, and authenticate using the OTP that you get via a text message. You can tap on the three dots on the top right, and enable biometric settings that will let you lock your Aadhaar to avoid misuse. And when you need to authenticate, simply unlock the biometric lock, which will be valid for 10 minutes.

You can download the mAadhaar app on your smartphone and login using your registered mobile number. This also does away the need of carrying a physical copy of Aadhaar card. What’s more, starting September 8, Indian Railways now accepts mAadhaar as one of the valid identity proofs for your rail travel.
