Agent-Resistant Authentication

MFA was built for humans.
Nobody told it about agents.

An AI agent can defeat standard MFA in 8 seconds. It uses valid credentials, leaves no trace, and can repeat the process indefinitely. Your security tools never alert.

CypherMFA requires a registered physical device to complete authentication. No device, no access. Unauthorized AI agents cannot pass that check — because there is no physical device to pass it with.

The Problem With Every MFA You Have Today

TOTP codes are retrieved by AI agents in milliseconds via API calls to password managers and authenticator apps. Push notifications are silently approved by agents that intercept the request. Passkeys stored in 1Password, Bitwarden, or any synced vault are accessible to any agent with access to that vault.

Most security teams don't know this. Most vendors don't say it. The credentials you think are protected are not protected from agents — because they were never designed to be.

How CypherMFA Is Different

The Only MFA Designed for the Agent Era

Device-Bound. Agent-Resistant.
Authentication completes only when a human holds a registered physical device and completes a visual challenge. The private key never leaves the device's secure enclave. It cannot be retrieved via API, forwarded to another device, or automated.

Integrates natively with Entra, Okta, and Ping. Drop-in replacement for TOTP and push notifications. No architecture changes required.
Secure Access Delegation
Authorized access can be securely delegated without sharing credentials or devices. Delegation is time-bound, revocable, and fully auditable. This is how enterprise teams manage access at scale — and how security teams govern who — or what — is operating in their environment.

Built for Every Layer of Your Stack

  • Agent-resistant: no physical device, no access
  • Drop-in: works with Entra, Okta, and Ping
  • No hardware: your phone is the device
  • Phishing-resistant: TOTP, push, and passkey relay all defeated
  • Delegation: time-bound, auditable, no credential sharing
  • Full audit trail: every session logged with device and identity
How It Works

One Additional Step.
Unbreakable by Design.

Standard Login

User authenticates through your existing SSO — Entra, Okta, Ping, or direct API. Nothing changes for the user at this step.

CypherMFA Challenge

A visual cryptographic challenge is sent to the user's registered physical device. The private key never leaves the device's secure enclave.

Physical Confirmation

The user completes the challenge on their device. Session opens. An unauthorized AI agent without the physical device cannot reach this step — no device, no access, full stop.
