Security Key (WebAuthn)

Quant0 supports hardware security key authentication using the WebAuthn standard. A compatible security key can be registered with your Quant0 account and used as an authentication method without relying solely on a password.

What Is a Security Key?​

A security key is a physical authentication device that securely stores cryptographic credentials used to verify your identity.

With WebAuthn, the security key communicates with your browser during authentication and proves that the registered credential is available.

Configure a Security Key​

To register a security key with your Quant0 account:

My Account → Password & Authentication → Passkeys → Create Passkey

  1. Open My Account from the left navigation menu.
  2. Select Password & Authentication.
  3. Locate the Passkeys section.
  4. Click Create Passkey.
  5. Connect your compatible security key to your device.
  6. Follow the authentication prompt displayed by your browser.
  7. Complete the security key verification when prompted.
  8. After successful verification, the security key is registered with your Quant0 account.

Sign In Using a Security Key​

Once your security key has been registered:

  1. Open the Quant0 Sign In page.
  2. Select Sign in with passkey.
  3. Select USB security key from the available authentication options.
  4. Connect your registered security key.
  5. Follow the browser's WebAuthn authentication prompt.
  6. Complete the security key verification.
  7. Quant0 verifies the credential.
  8. After successful verification, you are signed in to your account.

Security Key Requirements​

The security key must support the authentication capabilities required by WebAuthn/FIDO2.

The key must also be available and connected when performing authentication.

Note: The exact browser prompt and verification process may vary depending on the security key, browser, and operating system.

Managing the Security Key​

Registered security keys are managed through the Passkeys section:

My Account → Password & Authentication → Passkeys

From this section, users can manage their registered passkeys and authentication credentials.

If a security key is no longer available or should no longer be used, remove the associated credential from the Passkeys section when the option is available.
