Single-factor authentication is no longer sufficient for many B2B products. Password-only logins increase the likelihood of account takeover through phishing, credential reuse, and password leaks. In MERN applications, adding TOTP can also become brittle if enrollment, secret storage, QR provisioning, verification, and recovery flows are not implemented carefully—leading to lockouts, poor UX, and security gaps.
DevionixLabs sets up multi-factor authentication (TOTP) for your MERN stack with a secure, user-friendly enrollment and verification experience. We implement the complete lifecycle: enabling MFA, generating and validating TOTP codes, and enforcing MFA at login without disrupting legitimate users.
What we deliver:
• Secure TOTP enrollment flow with QR code provisioning and secret handling aligned with best practices
• Backend verification endpoints with time-window tolerance and brute-force protection
• Frontend MFA challenge screens integrated into your existing login flow
• Recovery and edge-case handling guidance (e.g., resync, invalid attempts, and safe failure messaging)
We also ensure the MFA experience is consistent across environments and that the system integrates cleanly with your session strategy. DevionixLabs configures rate limits and verification attempt controls to reduce the risk of OTP guessing.
The outcome is stronger account security with minimal friction. Your users get a clear, guided MFA setup, while your organization reduces the blast radius of compromised credentials.
With DevionixLabs, you’ll have a production-ready TOTP MFA system designed for reliability, security, and maintainability in your MERN application.
