Key Benefits
Authenticate Smarter Across The Customer Journey
Streamline Customer Experience With Recognized, Frictionless Identity
Verify users behind the scenes without requiring them to enter codes or complete extra steps, streamlining their journey and driving higher customer acquisition and retention.
Stay Secure With Proactive And Persistent Authentication
Move beyond vulnerable authentication methods to a unified, key-management system that secures accounts with persistent, device-based keys that are more resilient to attack.
Reduce Identity Monitoring Costs With Continuous Re-Authentication
Reduce the high costs associated with unnecessary SMS OTPs and incorrect contact information by managing identity continuity and authentication from a single, unified platform.
User Begins Session
A returning user on a recognized device attempts an action requiring authentication (like logging in or validating a high-risk transaction).
Authenticate with Cryptographic Key
Prove first attempts passive authentication, like Prove's Prove Key and Mobile Auth, and silently verifying the device with a cryptographic key or sim validation.
Apply Global Fraud Policy
Rather than a stack of unlinked and often conflicting data signals, Prove’s Global Fraud Policy applies all Prove learnings on fraud trends, alerts, and nuanced data attributes into a unified, intelligent output, detailing the specific reason codes customers need for comprehensive risk management.
Receive Result
Prove returns a success or failure response, allowing the transaction to proceed or be blocked/reviewed.
Step-Up As Needed
If a key cannot be validated, Prove will waterfall to alternative authentication methods.
Bind Key to Device, If Missing
If step-up was required, we will bind a key to the users device after successfully logging in. This will allow for a seamless login next time.
Key Features
Synchronized, Not Patchworked
Bring together fragmented tools into a single, orchestrated framework.
Frictionless By Default
Authenticate passively in the background. Step up only when risk requires it.
Persistent Through Change
Maintain trust through lifecycle events – no re-enrollment, no friction, no gaps in security.
Cross-Channel Aware
Recognize users instantly – across devices, sessions, and channels.

Frequently Asked Questions
How is Prove Unified Authentication different from traditional MFA?
Unlike traditional MFA that relies on SMS codes, authenticator apps, or hardware tokens, Prove Unified Authentication uses cryptographic key binding tied to the user's device for passive background verification. Step-up authentication is only triggered when risk signals require it, making the default experience completely frictionless.
Does Prove Unified Authentication work across devices?
Yes. Prove Unified Authentication provides cross-channel awareness, instantly recognizing users across devices, sessions, and channels. Trust is maintained through lifecycle events like device changes or number updates without requiring re-enrollment.
How much can Prove Unified Authentication reduce authentication costs?
Prove Unified Authentication can reduce authentication costs by up to 50% by eliminating unnecessary SMS OTP spend. An estimated 60% of SMS OTP spend is wasted on fraudsters, and SMS fraud costs businesses $1.16 billion annually. Prove replaces these costly methods with passive, cryptographic authentication.
What is Prove Unified Authentication?
Prove Unified Authentication is a passwordless authentication solution that replaces clunky OTPs and SMS-based verification with passive, persistent, device-based cryptographic key authentication. It seamlessly recognizes returning users across sessions, devices, and lifecycle changes without added friction.
