Adding two-factor authentication (2FA) to existing applications shouldn’t be hard — yet for many organizations, it still is. Legacy systems, custom web frameworks, or older stacks like Java, PHP, Python, .NET, and Node.js often lack native 2FA or MFA (multi-factor authentication) support, forcing teams into lengthy development projects or code rewrites.
With Datawiza Access Proxy (DAP), you can add 2FA to any web app instantly — without touching your code. DAP acts as a 2FA Reverse Proxy, enforcing modern 2FA (MFA) protection across any tech stack in minutes.
What Is a 2FA Reverse Proxy?
A 2FA (MFA) reverse proxy is a gateway that sits in front of your application. It intercepts login requests, authenticates users, and enforces two-factor authentication before access is granted — all without modifying your source code.
Datawiza Access Proxy delivers this capability through a no-code, cloud-ready architecture designed for maximum compatibility across diverse tech stacks.
Why Adding 2FA Is Traditionally Difficult
If your application was built years ago, integrating MFA typically means:
- Modifying your authentication logic
- Installing SDKs or agents
- Re-deploying or refactoring code
- Maintaining complex integration dependencies
These challenges slow down security rollouts and increase the risk of errors or downtime.
DAP solves all of this — no code, no SDKs, no changes to your login flow.
Architecture Overview
Datawiza Access Proxy (DAP) acts as a security layer between your users and applications. It seamlessly adds a second-factor authentication step right after your app validates user credentials — without requiring any code changes.
Step-by-Step Flow:
- The user visits your application (e.g., portal.example.com ).
- The user signs in using the existing login page — no changes needed.
- Your application authenticates the credentials (username and password) as usual.
- Upon successful validation, the user is automatically redirected to the Datawiza 2FA service by the proxy.
- Datawiza prompts the user for a second factor — such as an authenticator app code, email OTP, or SMS verification.
- Once 2FA is successfully completed, Datawiza returns the user to your application with a verified session and access granted
