Learn about Verify 2FA

A simple second factor without phones

Typing-based identity verification

Verify 2FA analyzes how a user types a short 4-word challenge and compares it with their enrolled typing pattern to verify identity.

Privacy-conscious by design

Verify 2FA focuses on how users type rather than the content itself, providing an authentication signal based on typing behavior.

No extra authentication device

Users authenticate with the keyboard already in front of them, without relying on a personal phone, authenticator app, or hardware token.

A better MFA/2FA experience for phone-restricted environments

No personal phone required

Verify 2FA is useful where employees cannot or should not use personal phones for work authentication, including secure offices, healthcare environments, BPOs, and restricted workspaces.

A fast 4-word challenge

Users simply type the 4 words displayed on screen. The experience runs in the browser and can be completed in seconds.

Works with your existing IAM

Verify 2FA is available for Okta, Microsoft Entra ID, Keycloak, Ping Identity, and ForgeRock through OIDC, or it can be integrated directly as a standalone solution.

Reduce the operational burden of traditional MFA

No hardware tokens to manage

Verify 2FA does not require purchasing, distributing, replacing, or recovering physical authentication tokens.

No authenticator app rollout

Because authentication happens in the browser, users do not need to install or maintain a dedicated authenticator app.

Simpler support for users

There is no separate device to forget, lose, replace, or leave behind, helping reduce common authentication support issues.

How Verify 2FA works

Enrollment

Enrollment

The user completes a short typing enrollment so Verify 2FA can enroll their typing style.

Verification

Verification

When a second factor is required, the user types the 4 words shown on screen and the typing pattern is compared with their enrolled typing style.

Access

Access

If the typing pattern matches, Verify 2FA confirms the user and the authentication flow can continue.

SMS Plus

Already using SMS OTP? Strengthen it with SMS+

If your organization still relies on SMS OTP, TypingDNA SMS Plus (SMS+) adds typing biometrics without replacing the familiar flow.

Instead of sending the OTP directly in the SMS message, SMS+ sends a secure link. The user opens it and types 2 words in the mobile browser. If the typing pattern matches, the OTP is revealed and entered as usual.

SMS+ works with most IAM platforms through custom gateway provider or telephony inline hook integration, uses your existing SMS provider, and requires no authenticator app.
