Prove Launches Unified AuthenticationSM

Prove’s Unified Authentication is delivering persistent recognition across onboarding, servicing, authentication, and payments – enabling businesses to engage customers securely, seamlessly, and at scale.

Prove has announced the launch of Unified AuthenticationSM, a modern authentication solution that passively and persistently recognises customers, no matter where they appear or how often their devices or credentials change.

This launch reflects a market shift: identity is no longer just a tool for fraud prevention or compliance – it is now a core enabler of digital commerce. Businesses must seamlessly recognise and authenticate customers across mobile apps, desktops, kiosks, call centres, and third-party platforms.

While device fingerprinting, behavioural biometrics, and passkeys each add value, none single-handedly solves the challenge of reliably identifying returning users throughout their lifecycle. 

Device fingerprints are probabilistic, biometrics can drift, and while passkeys sync for convenience, they no longer prove possession of a specific device on their own. As a result, many organisations revert to outdated methods that compromise both security and experience.

Prove’s Unified Authentication solution solves these challenges by harnessing the strengths of these technologies – and addressing their limitations – through a layered, orchestrated approach.

At its core is the Prove KeySM, a next-generation cryptographic key that is persistently bound to a user’s identity and secured directly on the device. Paired with real-time signal intelligence and advanced key management, the Prove Key delivers continuous, cross-channel authentication that endures through every lifecycle event.

Key capabilities:

• Combines device fingerprinting, behavioural biometrics, and passkeys while addressing their limitations, delivering passive MFA with two strong factors and dynamic linking to support PSD2 and PSD3 compliance.
• A passive, identity-bound cryptographic credential that enables seamless reauthentication without re-enrollment, even when new keys are issued after device changes or number updates.
• Operates across apps, browsers, desktops, kiosks, call centres, and third-party platforms to support portable “passport-like” digital experiences.
• Maintains identity persistence through lifecycle events like device upgrades, SIM swaps, carrier ports, and phone number changes.
• Provides real-time protection against synthetic identities, stolen credentials, scams, mules, and social engineering.

The result: less fraud, reduced costs, reduced abandonment, and measurable ROI through improved CX and long-term loyalty.

“Key-centric authentication is a valuable tool for fraud prevention,” said John Snyder, Senior Manager, Product at BetMGM. “It’s a great way to scale up fraud control without sacrificing user experience, making things easy for good users and hard for bad ones.”

“At Prove, we’ve always believed identity is the gateway to a new generation of digital experiences,” said Rich Rezek, Head of Platform and Solution Strategy at Prove.

“With Unified Authentication, we’re bringing that vision to life – synchronising identity and authentication in a more sophisticated way than ever before to eliminate friction, build trust, and protect every step of the customer journey, from onboarding to recovery and beyond.”
