Up and running in minutes

Simple MFA integrates with your existing BigCommerce store without touching your theme files.

1

Install the app

Install Simple MFA from the BigCommerce App Marketplace. OAuth handles permissions automatically — no manual API key setup.

2

Add one script tag

Copy the generated script tag from the admin panel and paste it into Storefront → Script Manager. That's the only storefront change needed.

3

Customers log in securely

Login links are transparently redirected to a hosted, branded login page. Customers set a password on first login and can optionally enrol in TOTP MFA.

Everything you need to secure customer accounts

🔐

Owned password management

Passwords are hashed using PBKDF2-SHA256 (NIST SP 800-63B compliant) and stored securely — entirely separate from BigCommerce.

📱

TOTP authenticator support

Customers can enrol any RFC 6238 TOTP app — Google Authenticator, Authy, 1Password, and more. Backup codes included.

✉️

Seamless first-login migration

Existing customers are migrated automatically. A magic link email lets them set their password on first login — no manual re-registration.

🎨

Custom branding

Upload your logo and set your brand colours. The hosted login page matches your store identity.

📊

Auth logging and monitoring

Every login attempt is logged with IP address and user agent. View per-customer history and store-wide suspicious activity from the admin panel.

🛡️

Rate limiting and IP throttling

Automatic lockout after repeated failures. Cloudflare-native threat scoring blocks suspicious IPs before they reach your store.

Built for Stencil storefronts

Simple MFA works with any BigCommerce store running a Stencil theme — including Cornerstone and all marketplace themes.
