Add 2FA/MFA to Any External App, Portal, or Website — Without Code

Why External or Public-Facing Apps Need MFA Now

Customer, partner, and vendor portals are prime targets for cyberattacks. These internet-facing applications—often built years ago—were never designed for today’s security requirements. Many still rely on basic username and password logins, leaving organizations exposed to:

• Credential stuffing and brute-force attacks
• Account takeovers and data leaks
• Compliance risks (SOC 2, ISO 27001, NYDFS, HIPAA, etc.)

According to Verizon’s Data Breach Investigations Report, over 80% of breaches involve stolen or weak credentials. The easiest fix? Add multi-factor authentication (MFA) or two-factor authentication (2FA )to every public or external app.

But for many IT teams, that’s easier said than done.

The Challenge: Adding MFA to Legacy or 3rd-Party Apps

Most organizations have dozens of web apps for customers, partners, and vendors—running on different tech stacks (Java, PHP, .NET, Python, etc.), hosted on-prem or in private data centers.

Common pain points:

• The apps don’t have built MFA or 2FA.
• The apps don’t support modern authentication (OIDC, SAML)
• The source code is closed or vendor-controlled
• Developers are unavailable or busy
• Projects get delayed due to custom coding and testing

That’s where Datawiza comes in.

The No-Code Solution: Add MFA Without Modifying Your App

Datawiza Access Proxy makes it possible to add 2FA/MFA to any web application—without touching the source code. It sits in front of your existing app as a reverse proxy and integrates seamlessly with your current login flow.

How It Works

1. User visits your existing app (e.g., portal.example.com ).
2. User logs in with their usual username and password.
3. Your app authenticates the credentials as before.
4. Datawiza Proxy intercepts the session and redirects the user to the Datawiza 2FA service for a second-factor check.
5. User completes MFA using an authenticator app, email OTP, or SMS code.
6. Once verified, Datawiza returns the user to your app with a validated session—access granted.

No code changes. No re-architecture. No deployment headaches.

Supported MFA Methods

Datawiza supports a variety of MFA options to meet enterprise security and user-experience needs:

• 🔐 Authenticator Apps (Microsoft Authenticator, Google Authenticator, Okta Verify, etc.)
• 📧 Email One-Time Passcodes (OTP)
• 📱 SMS Verification Codes
• 🗝️ FIDO2/WebAuthn Passkeys (Passwordless Login)

You can easily enable or disable MFA per app, per user group, or per policy in the Datawiza Management Console.

Works with Any Tech Stack or Hosting Environment

Whether your apps are written in Java, PHP, Python, .NET, Node.js, or something older, Datawiza works without requiring code modification.

Supported environments include:

• On-prem servers or data centers
• AWS, Azure, or GCP cloud environments
• Docker, Kubernetes, or VM-based deployments
• Even 3rd-party vendor apps with internal authentication systems

Example: An insruance company added MFA to its customer portal running on legacy PHP within 30 minutes—no developer involvement.
