KZero Passwordless Authentication

Fast, Secure, Phishing-Resistant Access

Passwordless authentication removes the need for passwords, replacing them with secure biometrics and cryptographic keys.

High-Level Benefits

With KZero, passwordless means more than convenience and security. It means:

No time-based OTP codes to intercept

No passwords to phish, steal, or forget

No friction or frustration for users

Why KZero is Better?

Why Passwordless is Better

Traditional MFA and SSO solutions still depend on shared secrets like passwords, PINs, or OTPs. These are vulnerable to phishing, man-in-the-middle attacks, and social engineering. Passwordless authentication eliminates this threat surface.

With KZero Passwordless, You Get:

Phishing-resistant MFA by default

Better security without user pushback

Faster, single-step login with biometrics

Fewer helpdesk tickets and lockouts

Improved MFA adoption and compliance

It’s a smarter, simpler way to authenticate.
How it Works

How KZero Passwordless Works

Device-Bound Passkeys + Biometrics
KZero uses device-bound passkeys and public-key cryptography stored securely on the user’s device or smartcard. The private key is unlocked using biometrics and never shared or transmitted.

Authentication flow:

A login request triggers a cryptographic challenge

The user unlocks their device using biometrics (ex. fingerprint or face)

The device signs the challenge using its private key

The signed response is verified using the public key

→ Login complete—no passwords, no phishable codes

We were seeing a spike in phishing attempts and needed a better way to protect our clients without adding friction for their users. We had heard of passwordless but assumed it would be complicated to roll out. KZero completely changed that. Implementation was faster than expected, and MFA adoption became simple and seamless. KZero made the entire process easier for us and our clients.

FAQ

What is passwordless authentication?

Passwordless authentication replaces traditional login methods like passwords and codes with secure, cryptographic credentials tied to a user’s device. Instead of typing a password, users authenticate with something they have (a phone or smartcard), something they know (a cryptographic key), and something they are (biometrics), completing the login with a single action.

How does passwordless authentication improve security?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

How does passwordless authentication improve convenience?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

What are device-bound passkeys?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

What happens if a user loses their device?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

Is passwordless authentication the same as MFA?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

Can KZero Passwordless work with legacy or non-SSO apps?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks. But by using other systems such as biometrics or hardware signing devices, passwordless authentication provides a more secure and convenient way for users to authenticate themselves. This method eliminates the need for passwords and the associated risks, making it a popular choice for organizations looking to improve security, productivity, and user experience for their consumers and workforce.

How does KZero support Zero Trust?

Passwords come with inherent vulnerabilities due to the prevalence of weak passwords, password reuse, and social engineering attacks.
