Digital Identity Authentication Without Fraud or Friction
Passkeys for everyday journeys. Patented split-key authentication for high-trust moments.
One verified customer identity, built for compliance and security.

Why Traditional Authentication Fails
Passwords, OTPs, and device-blind MFA weren’t built for today’s threat landscape. Phishing kits, session hijacking, and account takeover attacks make traditional authentication the weakest link and the easiest way in.
Compromised credentials were the initial access vector in 22%* of breaches with password-led journeys the biggest exposure.
-
SMS codes and OTP flows add effort but not assurance. NIST views manually entered codes as "not phishing-resistant".
-
Customers expect faster, low-friction access, while standards bodies recommend cryptographic methods for strength.

Authenticate Every Interaction
Ditto Authenticate replaces fragile credentials and OTPs with deterministic, device-bound trust, securing logins and approvals without adding friction.
Passwordless Login
Eliminate credential-based risk with device-bound login that’s instant for users — and leaves attackers with nothing to steal.
Multi-Factor Authentication
Strong customer authentication powered by device integrity, biometrics and split-key cryptography.
Transaction Signing
Every high-risk action is signed using a private cryptographic key bound to the user’s trusted device, ensuring approvals can’t be forged or intercepted.
Adaptive Step-Up
Trigger biometric or device-based step-up authentication during suspicious behaviour, compromised sessions, or high-value transactions.
Match authentication strength to the moment
Not every interaction carries the same risk. Rather than forcing every login and every transaction through the same heavy process, Ditto Authenticate applies the right level of assurance to the right moment, all bound by a single verified identity.
LOW ASSURANCE JOURNEYS
Passkeys for everyday access
- Standards-based WebAuthn and FIDO2 authentication for high-volume, lower-risk interactions like routine login and balance checks.
- Phishing-resistant, origin-bound, and quick to deploy. It removes password dependence without over-engineering the journey.
HIGH ASSURANCE JOURNEYS
Split-key cryptography for strong trust
- For higher risk actions like payments, account recovery, profile changes and document signing, Ditto applies its patented split-key authentication.
- Cryptographic trust is bound to the device and the specific interaction, delivering the assurance and traceability these moments demand.
Split-key cryptography brings strength
Ditto's high-assurance patented protocol, Relative Mutual Authentication and Key-exchange (RMAK), uses a unique cryptographic key that is split in two when a customer and an organisation establish a relationship. Neither side ever holds the whole key.
Mutual proof, every session
Both halves prove themselves simultaneously on every authentication. No certificate authority, no third party to trust.
Man-in-the-middle resistant
Each session opens an encrypted tunnel with Perfect Forward Secrecy stopping an attacker intercepting and impersonating either party .
Quantum-resistant by design
The protocol is crypto-agnostic, with algorithms already aligned to NIST post-quantum standards (FIPS 203, 204, 205). Built in, not bolted on.
Why Organisations Choose Ditto Authenticate
Ditto Authenticate replaces fragile, guessable, and spoofable factors with matched authentication strength that builds trust across every journey.
A Headache for Hackers
Split-key cryptography binds authentication to a trusted device and the session it’s initiated from, making phishing, replay and push-fatigue attacks ineffective.
No More Weakest Link
No passwords to steal, no SMS codes to intercept, no approval prompts to manipulate. Just deterministic, device-bound trust.
Built for Compliance
Ditto supports PSD2, SCA, and eIDAS-aligned authentication across login, step-up, and transaction flows — without introducing unnecessary friction.
In-Flow Transaction Signing
Each transaction is cryptographically signed using a private key secured on the user’s device, to prevent forged, coerced, or tampered approvals.

Ditto simplifies identity and transaction authentication — ensuring the right people can access the right things, every time.
Designed For Enterprise Authentication
Split-key cryptography, risk based authentication strength, and trusted device signals work together to replace fragile credentials with deterministic, tamper-proof authentication across all digital journeys.
Use cases
The Ditto Authenticate Difference
Step-Up Authentication
Trigger stronger checks only when risk requires it.
Deploy biometric or cryptographic enforced step-ups for suspicious behaviour, compromised sessions, or high-value actions.-
Transaction Signing
Capture cryptographic proof of user intent for payments and sensitive changes, providing tamper-proof, non-repudiable records.
-
EUDI Intermediary Services
Use wallet attestations as strong authentication factors for login and transaction approval. Orchestrate flows where EUDI credentials sit alongside existing factors to meet future regulatory expectations.
-
Caller Verification
Authenticate callers before support conversations begin. Use device-bound identity to confirm the customer’s legitimacy and stop social engineering attacks.
