Biometric Security & Hardware Telemetry

Face ID, fingerprint, and secure enclave authentication — the security users expect, built to platform standard

Biometric authentication (Face ID, Touch ID, Android biometric APIs) lets users unlock sensitive actions — logins, payments, app access — without typing a password, backed by the device’s secure hardware enclave rather than storing biometric data in the app itself. We implement it to platform security standard, alongside hardware telemetry for device-level fraud and risk signals.
The security model here matters as much as the convenience: the app never actually receives or stores a fingerprint or face scan. The device’s operating system performs the biometric match inside a dedicated secure hardware chip and returns only a yes/no result — the app simply asks the OS "did the enrolled user just authenticate?" and gets a boolean answer. That’s what makes biometric auth genuinely more secure than a password, not just more convenient: there’s no biometric data to leak from a server breach because it was never sent to a server.

Implementation

How We Actually Build This

1

Biometric prompts use the platform’s native APIs (LocalAuthentication on iOS, BiometricPrompt on Android) rather than a custom implementation, inheriting the OS’s security guarantees

2

Sensitive actions (payment confirmation, credential access) require a fresh biometric check rather than relying on a session that was authenticated minutes earlier

3

A secure fallback (PIN or password) is always available for the small percentage of users or moments where biometric hardware isn’t accessible

4

Device-level telemetry (jailbreak/root detection, unusual usage patterns) feeds into a risk score used to flag potentially fraudulent sessions

Key Benefits

Why Biometric Security & Hardware Telemetry Is the Right Choice

Frictionless authentication increases login and payment completion rates

Biometric data never leaves the device’s secure hardware enclave

Meets the security bar users now expect from banking and payment apps

Hardware telemetry adds fraud-detection signal beyond passwords alone

Reduces support burden from forgotten passwords

Proven at Scale

Companies Building on This Technology

Major banking apps (Chase, Revolut and peers)

use biometric authentication as the default login method for account access

Where This Applies

Common Use Cases

  • Banking and fintech apps requiring strong authentication
  • Payment confirmation flows needing frictionless but secure approval
  • Healthcare apps handling sensitive patient data
  • Apps storing credentials or sensitive documents on-device

Frequently Asked Questions

Common Questions About Biometric Security & Hardware Telemetry

Does our app ever get access to the user’s actual fingerprint or face data?+

No — biometric matching happens entirely inside the device’s secure hardware enclave, controlled by the operating system. The app only receives a success or failure result, never the biometric data itself.

What happens if a user’s device doesn’t support biometrics?+

The flow falls back to a standard PIN or password automatically — biometric authentication is always an enhancement on top of a traditional credential, never a hard requirement that locks users out.

Can biometric authentication be spoofed?+

Modern implementations (Face ID’s depth-sensing, Android’s hardware-backed biometric classes) are built specifically to resist photo/video spoofing, and we only use the platform’s certified "strong" biometric classes for security-sensitive actions.
