Biometric authentication

The future of authentication is biometrics. If you’re ready, we are too.

FIDO Biometrics

Open the mobile app and you’re prompted to authenticate using your fingerprint or facial recognition. That’s it!

Why biometric passwordless authentication

More secure

More than 80% of data breaches are due to weak or stolen passwords. Passwordless biometrics means no credentials to steal. FIDO certification, the de facto standard for strong authentication, ensures public key infrastructure (PKI), elimination of server-side secrets, and on-device-only verification of biometrics so data can’t be intercepted and stolen.

User-friendly & frictionless

Don’t make users type in passwords or passcodes. Instead, easily authenticate by scanning fingerprint or face on a mobile device to authenticate or unlock user credentials.

Mainstream & ubiquitous

Leverage the technology people are already using. More than two-thirds of consumers say they’re comfortable using biometric authentication on their smartphones.


No matter what the future brings, ensure interoperability of your apps and systems with the latest platforms and biometric technologies that people want to use – cost effectively.
