How to Check Aadhaar Authentication History Online (Step-by-Step Guide)

The Aadhaar number is used in various identity verification processes across banks, telecom providers, government portals, and more. Every time you authenticate your identity using Aadhaar — whether via OTP, fingerprint, or iris — it’s recorded by the Unique Identification Authority of India (UIDAI).

Want to know where and when your Aadhaar was used? You can easily check your Aadhaar authentication history online, directly from the UIDAI portal. This helps you monitor suspicious activity and stay in control of your digital identity.

In this detailed guide, we’ll explain everything you need to know about Aadhaar authentication history, why it’s important, and how to check it safely.

🧾 What Is Aadhaar Authentication?

Aadhaar authentication is the process where your Aadhaar number, along with your biometric or demographic data (like OTP, fingerprint, iris scan), is validated against the UIDAI database.

It’s used in scenarios such as:

• Opening a bank account

• e-KYC for SIM card issuance

• Applying for government schemes (PM Kisan, scholarships, etc.)

• Logging in to government portals like Digilocker, PMGDISHA

Each time Aadhaar is used for authentication, UIDAI records the time, mode, and requesting agency.
