screen

reportWebAuthnError

• reportWebAuthnError(
      options: Screens.MfaWebAuthnRoamingChallengeReportErrorOptions,
  ): Promise<void>

  Reports a specific WebAuthn API error to Auth0. This method should be used if navigator.credentials.get() fails in a way that verify() doesn't automatically handle, or if the developer wants to explicitly report an error before trying another action. It submits the error details with action: "showError::{errorDetails}".

  Parameters

  • options: Screens.MfaWebAuthnRoamingChallengeReportErrorOptions

    Contains the error object with name and message from the WebAuthn API, and any other custom options.

  Returns Promise<void>

  A promise that resolves when the error report is submitted.

  Throws

  Throws an error if the form submission fails.

  Example

  // Assuming 'sdk' is an instance of MfaWebAuthnRoamingChallenge
  // And webAuthnError is an error object from a failed navigator.credentials.get() call.
  try {
    await sdk.reportWebAuthnError({
      error: { name: webAuthnError.name, message: webAuthnError.message }
    });
  } catch (submitError) {
    console.error("Failed to report WebAuthn error:", submitError);
  }
  Copy

tryAnotherMethod

• tryAnotherMethod(
      options?: Screens.MfaWebAuthnRoamingChallengeTryAnotherMethodOptions,
  ): Promise<void>

  Allows the user to opt-out of the WebAuthn challenge and select a different MFA method. This action submits action: "pick-authenticator" to Auth0, which should navigate the user to an MFA factor selection screen.

  Parameters

  • Optionaloptions: Screens.MfaWebAuthnRoamingChallengeTryAnotherMethodOptions

    Optional custom parameters for the request.

  Returns Promise<void>

  A promise that resolves when the action is submitted.

  Throws

  Throws an error if the form submission fails.

  Example

  // Assuming 'sdk' is an instance of MfaWebAuthnRoamingChallenge
  try {
    await sdk.tryAnotherMethod();
    // On success, Auth0 handles redirection to MFA selection.
  } catch (error) {
    console.error("Failed to switch MFA method:", error);
  }
  Copy

verify

• verify(options?: Screens.VerifySecurityKeyOptions): Promise<void>

  Initiates the WebAuthn challenge by calling navigator.credentials.get() with the options provided in screen.data.publicKeyChallengeOptions. If successful, it submits the resulting credential to Auth0 with action: "default". If navigator.credentials.get() fails with a known WebAuthn API error (like NotAllowedError), this method will internally call reportWebAuthnError to inform Auth0.

  Parameters

  • Optionaloptions: Screens.VerifySecurityKeyOptions

    Optional parameters for the verification process, such as rememberDevice and other custom options.

  Returns Promise<void>

  A promise that resolves when the verification attempt is submitted. It does not directly return data as a successful operation typically results in a redirect.

  Throws

  Throws an error if screen.data.publicKeyChallengeOptions is missing, if navigator.credentials.get() fails with an unexpected error, or if the form submission to Auth0 fails.

  Example

  // Assuming 'sdk' is an instance of MfaWebAuthnRoamingChallenge
  try {
    await sdk.verify({ rememberDevice: true });
    // On success, Auth0 handles redirection.
  } catch (error) {
    console.error("Security key verification failed:", error);
    // Check sdk.transaction.errors for server-side validation messages if the page reloads.
  }
