UIDAI adds dynamic OTP to its mAadhaar app; here’s how to access it

The new feature will help users to authenticate without having to wait for the OTP.


The Unique Identification Authority of India (UIDAI), an agency that administers Aadhaar, has introduced a new feature in its mAadhaar app. Called time-based one-time password (TOTP), the feature 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.

“TOTP has been configured in the Self Service Update Portal (SSUP) and eAadhaar download,” Ajay Bhushan Pandey, CEO, UIDAI told ET. “In future, all OTP based Aadhaar authentication applications will be migrated to TOTP based Aadhaar authentication,” he added. For those unaware, the dynamic OTP is an 8-digit number that is generated as an OTP within the app using some algorithm, and it keeps changing in every 30 seconds.

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. Pandey further added saying “TOTP addresses OTP related shortcomings like residents dependency on mobile network for SMS delivery, etc.”

Here’s where you can find the dynamic OTP in mAadhaar app

Since its launch in July this year, the mAadhaar app has been downloaded over one million times. 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.

Now, to access TOTP, open the app, punch in your profile password. You will see your Aadhaar details here, followed by a lock icon on the right corner. Tap on it, and once again confirm the profile password to unlock it. On the bottom of the home screen, tap on the bell icon saying ‘show TOTP.’ It will open a new screen showing you the TOTP.

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.
