DigiYatra: How to Use It and Wipe Your Face Data

If you fly often within India, you have probably seen the green-lit gates where some passengers glance at a camera and walk through while everyone else fumbles for an ID card. That is DigiYatra, the face-recognition system that now lets travellers clear airport entry, security and boarding without showing a physical document. It is fast and genuinely convenient. It is also one of the most quietly consequential pieces of consumer technology India has rolled out, and most people sign up without reading a word about where their face goes.

Here is the practical part most guides skip: how DigiYatra actually handles your data, how to use it well, and crucially, how to delete everything and walk away if you change your mind.

What DigiYatra actually is

DigiYatra is a biometric boarding system run by the DigiYatra Foundation, a non-profit set up jointly by the Airports Authority of India and a group of major private airport operators. The idea is simple: link your face to your travel ID once, and from then on cameras verify you at each checkpoint instead of human staff scanning your card.

Two things are worth fixing in your mind from the start. First, it is optional and free — nobody can force you onto it, and the regular queues with physical ID still exist. Second, it is not a single national face database in the way critics sometimes imply. The system was deliberately built so your face template lives on your own phone, encrypted, rather than on a central government server.

How your face data is handled

The design choice that matters most is decentralisation. When you enrol, your identity and a facial template are stored in a secure wallet inside the app on your device. You are the one holding the credential, not a remote database.

When you travel, the app shares your details and face data only with the specific airport you are flying from, and only for that journey. The matching happens at the gate against what you have shared. After your flight, the policy is that this travel data is deleted within 24 hours. The DigiYatra Foundation says it audits enrolled airports annually to check that the deletion scripts are actually running as promised.

That is the official architecture, and on paper it is more privacy-respecting than a centralised face registry. The honest caveat is that you are trusting the foundation and each airport operator to honour it, and to secure the systems that briefly hold your data on travel day.

Why privacy researchers are still watching

The convenience is real, but so is the scrutiny. A case is currently before the Delhi High Court that effectively tests whether DigiYatra lives up to its own privacy commitments — the kind of legal pressure that tends to sharpen how a system treats user data over time.

There are a few unresolved tensions worth knowing before you opt in:

• Aadhaar-only KYC. As of 2026 the only way to register is through Aadhaar-based verification. There is no alternate-document path, which means everyone who uses DigiYatra is linking airport movement to their Aadhaar identity.
• Function creep. A face-at-the-gate system built for airports is exactly the kind of infrastructure that other agencies and venues may want to plug into later. Today's narrow use is not a guarantee of tomorrow's.
• Consent in a hurry. Many people enrol at the airport itself, minutes before a flight, tapping through screens they would never read at home.

None of this makes the app unsafe to use. It does make a strong case for treating enrolment as a deliberate decision rather than a default.

How to enrol, step by step

If you do want the faster queue, setting up takes a few minutes and is best done before you reach the airport.

1. Download the official DigiYatra app from the Play Store or App Store. Check the publisher carefully, because lookalike apps exist.
2. Register with your mobile number and complete Aadhaar-based KYC to verify your identity.
3. Capture a clear selfie when prompted — this becomes your stored face template. Good lighting and a plain background help future matches.
4. On travel day, add your boarding pass by scanning it in the app, which links your face to that specific flight.
5. At the airport, use the dedicated DigiYatra e-gates at entry, security and boarding. Look at the camera, and the gate opens once you are matched.

A few practical tips. Keep your phone charged, because the credential lives on it. Update your selfie if your appearance changes significantly. And remember that DigiYatra clears the identity checkpoints — you still go through physical security screening of your bags and person like everyone else.

How to delete your data and deregister

This is the part worth bookmarking. If you decide DigiYatra is not for you, or you simply want to leave, you are not stuck.

• Per-trip data is designed to be purged automatically within 24 hours of your flight, so it does not accumulate journey by journey.
• Your account and stored credential can be removed by you directly. Open the app, go into your profile or settings, and look for the deregister or delete-account option. Completing this removes your registered ID and face credential from the app on that device.
• If you are switching phones, deregister on the old device or remove the app data so a stored credential is not left behind on hardware you no longer control.

Because the sensitive template sits on your phone rather than a central vault, uninstalling the app and deleting the account is a far cleaner exit than it would be with a server-side biometric system. That is one genuine upside of the decentralised design.

Where it is available, and where it is going

DigiYatra has expanded quickly. From a handful of metro airports at launch, it now operates at more than 30 airports and is set to expand to dozens more as Tier-2 and Tier-3 airports come online through 2026 and 2027. All the big metros are covered, and the foundation has signalled further additions this financial year.

International use is the next frontier being discussed, which would let the same face-based flow work on cross-border journeys — a far bigger data and legal question than domestic hops.

Should you use it?

For a frequent domestic flyer who values shaving minutes off three separate queues, DigiYatra is a reasonable trade. The on-device storage and 24-hour deletion are meaningfully better than the centralised-database alternative people often assume it is.

If you are uneasy about tying your travel pattern to Aadhaar, sceptical of how consistently deletion is enforced, or simply prefer to keep biometric checkpoints out of your routine, the old-fashioned line is still there and always will be. The smartest position is the informed one: use it because you understood the trade and chose it, not because a staffer waved you toward the green gate while your flight was boarding.
