Duo Security announced that the high level of security traditionally associated with hardware smart cards is now available on consumer mobile devices that use Duo’s two-factor authentication service.


Duo’s mobile app, commonly used for two-factor authentication in the enterprise, now leverages the hardware security module (HSM) embedded in the latest mobile devices to provide a secure, tamper-proof credential that cannot be copied or cloned. Duo takes advantage of the same hardware-backed technology present in modern Android devices that powers security-critical virtual wallet applications.

Duo’s new technology on select Android devices can provide a trusted platform for authentication, even in the face of such privilege escalation vulnerabilities. By storing the user’s private key material in the tamperproof HSM, the credential can not be stolen or cloned by an attacker, even if the user’s mobile device has been fully compromised.

“By leveraging the unique hardware security capabilities of modern Android devices, our Duo Push technology is not only the most user-friendly two-factor authentication in the market, but also the most secure,” says Dug Song, CEO of Duo Security. “Duo continues to lead and innovate in mobile security to ensure consumer mobile devices can act as trusted authenticators in the modern enterprise.”

Customers of Duo’s two-factor authentication service will begin enjoying the security benefits of a hardware-backed credential immediately and transparently on supported mobile devices.
