Step-up Auth

⚡ 15 min total

Add an extra security layer to protect sensitive actions with Multi-Factor Authentication (MFA/2FA)

Works without Transcodes Login! Step-up MFA is a standalone feature. You can keep your existing authentication system (Firebase, Auth0, custom implementation, etc.) and just add MFA functionality on top

What is Step-up MFA?

Step-up MFA triggers additional authentication when users perform sensitive actions. Instead of requiring MFA on every login, you only ask for it when it matters:

Admin panel access
Financial transactions
User Account deletion
Subscription cancellation
Data exports or deletions

Supported MFA Methods:

TOTP (Google Authenticator, Authy, 1Password)
Email OTP (6-digit verification code)
Hardware Security Keys (YubiKey, FIDO2 keys)

Integration Steps

Step 1: Prerequisites Step 2: Load the SDK (CDN or npm)Step 3: Open the MFA modal Step 4: Handle the MFA response

Quick start

Uses global transcodes after CDN load; with npm, import { openAuthIdpModal } after init.


// Trigger MFA before sensitive action
async function performSensitiveAction() {
  // 1. Request MFA verification
  const mfaResult = await transcodes.openAuthIdpModal({
    resource: 'sensitive_action',
    action: 'delete',
  });
 
  if (!mfaResult.success || !mfaResult.payload[0]?.success) {
    console.log('MFA verification failed or cancelled');
    return;
  }
 
  // 2. MFA verified - proceed with sensitive action
  console.log('MFA verified successfully');
 
  // 3. Perform the protected action
  await deleteUserData();
}
