Phishing-Resistant MFA

MFA that can't be fatigued, flooded, or talked around.

Attackers evolved past legacy MFA: fake pages intercept OTPs, SIM-swaps hijack SMS codes, and push-bombing wears users down until they tap approve. KZero replaces all of it with one biometric gesture and nothing to intercept.

The Problem

Legacy MFA was a start. It's no longer enough.

Phishing sites intercept OTPs

AI generates pixel-perfect fake login pages in seconds. The user types the code; the attacker relays it in real time.

SIM-swapping hijacks SMS codes

A social-engineered carrier transfer and every SMS-based factor now belongs to the attacker.

Push fatigue defeats prompts

Bombard a user with approval requests at 2am and eventually someone taps yes. Attackers know it; AI automates it.

The Solution

One gesture. Three factors. Zero phishable steps.

KZero's MFA is built on FIDO2, WebAuthn, and device-bound passkeys. A single biometric action verifies everything, with nothing transmitted that an attacker could capture or replay.

Something you have

The user's device, holding a device-bound passkey that never leaves it.

Something you are

Biometrics unlock the key locally: fingerprint or face, verified on-device.

Cryptographic proof

The device signs a one-time challenge; the server verifies it with the public key. Nothing to phish, intercept, or reuse.

At a Glance

Legacy MFA vs. KZero

Legacy MFA

KZERO Phishing-Resistant MFA

Relies on passwords and OTPs
No passwords, no codes to intercept
Vulnerable to phishing and relay attacks
Phishing-resistant by design
Push prompts invite MFA fatigue
No prompts to bomb: user-initiated biometric login
Friction users resent and bypass
Instant biometric sign-in users prefer
High reset and lockout burden
Drastically fewer helpdesk tickets
For MSPs

Built for speed, security, and compliance.

Slash reset tickets

Eliminate one of the biggest MSP time sinks by eliminating passwords.

Stop modern attacks

Block credential stuffing, phishing, and man-in-the-middle attacks that bypass traditional MFA.

Zero Trust & compliance ready

Aligned with Zero Trust principles and the phishing-resistant MFA requirements insurers and frameworks increasingly demand.

FAQ

How is this more secure than 2FA or traditional MFA?

Traditional MFA usually starts with a password, which can be phished, and adds a code, which can be intercepted. KZero removes both: the login is a local cryptographic exchange with no shared secret at any step.

Is passwordless the same as MFA?

No. Legacy MFA stacks extra steps on top of a password. KZero's approach is multi-factor by design: device plus biometrics in a single gesture, with no password underneath to attack.

Does invisible MFA hurt compliance evidence?

The opposite. Every login is a strong, logged, multi-factor cryptographic event, giving you cleaner audit evidence than inconsistently adopted legacy MFA.

How does it help with Zero Trust?

Every access decision is based on a verified user, a trusted device, and a secure authentication event rather than a password, which is exactly what Zero Trust frameworks call for.

Ready to leave legacy MFA behind?

It's not about more factors. It's about factors that can't be phished.
