Fix NSP Error 904: Face Auth and Biometric Lock Guide

Overcoming Technical Hurdles on the National Scholarship Portal (NSP)

For millions of students across India, the National Scholarship Portal (NSP) is the gateway to financial independence. However, with the transition to Aadhaar-based authentication, many applicants are encountering technical roadblocks. Specifically, Error 904 and issues related to biometric locks have become common pain points.

At YojanaRadar, we understand that a technical glitch shouldn't stand between you and your education. This comprehensive guide will walk you through the exact steps to troubleshoot Face Authentication failures and manage your Aadhaar security settings to ensure your application is submitted before the deadline.

Understanding Error 904 on NSP

Error 904 typically occurs during the final stages of the NSP application when the system attempts to verify the student's identity via the Aadhaar FaceRD service. This error usually points to one of three things: a communication failure between the NSP app and the UIDAI servers, an outdated version of the FaceRD app, or a temporary lock on your Aadhaar biometric data.

When you see this error, the system is essentially saying it cannot "read" your live facial data to match it with the records stored in the Aadhaar vault. Don't panic; it is rarely a permanent issue with your profile.

Step-by-Step Fix for NSP Face Authentication

To successfully complete your Face Authentication, follow this precise workflow:

• Update the Apps: Ensure you have the latest version of the NSP Mobile App and the Aadhaar FaceRD (Early Access) app installed from the Google Play Store. The FaceRD app does not have a typical "Open" button; it acts as a background service.
• Check Device Compatibility: Face Authentication requires a smartphone with at least 5MP front camera and Android 7.0 or higher. Ensure you are in a well-lit room with a plain background.
• Clear Cache: Go to your phone's Settings > Apps > Aadhaar FaceRD > Storage and click "Clear Cache." Repeat this for the NSP App.
• Permissions: Ensure the NSP app has permission to access your camera and location.

Managing Aadhaar Biometric Locks

One of the most frequent causes of authentication failure is a "Locked" biometric status. For security reasons, many users (or the system by default) lock their biometrics to prevent unauthorized access. However, this lock prevents the NSP portal from verifying your identity.

To fix this, you must use the mAadhaar app or the official UIDAI website:

1. Using mAadhaar App: Login to the app, navigate to 'My Aadhaar', and check the 'Biometric Lock' status. If it is red/locked, click to 'Unlock' or 'Disable' the lock temporarily.
2. Using UIDAI Website: Visit the MyAadhaar portal, log in with your OTP, and navigate to 'Lock/Unlock Biometrics'. Ensure the status is set to 'Unlocked' before attempting the NSP Face Auth again.

Important Note: A 'Temporary Unlock' lasts for 10 minutes. Ensure you trigger the NSP authentication immediately after unlocking.

Common FaceRD Failure Reasons and Solutions

If you are not seeing Error 904 but the face scan keeps failing, consider these environmental factors:

• Lighting: Avoid backlighting (light coming from behind you). The light should be hitting your face directly.
• Distance: Hold the phone about 1-2 feet away. The app will guide you to "move closer" or "blink" your eyes to prove liveness.
• Stability: Use a tripod or lean your phone against a solid object to avoid motion blur.

Summary Checklist for Students

Before you try your next login, run through this checklist to save time:

• Is your Aadhaar linked to your current mobile number?
• Is your Aadhaar Biometric Lock disabled?
• Is the Aadhaar FaceRD app updated?
• Are you using a stable 4G/5G or Wi-Fi connection?

By following these steps, you can bypass Error 904 and successfully complete your NSP verification. If problems persist, you may need to visit a nearby Aadhaar Seva Kendra to update your biometric records (specifically your photo), as children's biometrics often need updating after age 5 and 15.
