ShieldAuth — MFA for Strapi v5

Secure your Strapi v5 admin panel with modern multi-factor authentication.

ShieldAuth ships with TOTP and recovery codes today, with Email OTP, SMS, and WebAuthn on the roadmap. All paid factors are unlocked by your ShieldAuth license — the plugin validates your key against the ShieldAuth backend on startup and once per hour thereafter.

✅ Requirements

🚀 Install

npm install strapi-plugin-shieldauth

⚙️ 1. Register the plugin

Add to your Strapi config/plugins.ts (or config/plugins.js):

export default ({ env }) => ({
  shieldauth: {
    enabled: true,
    config: {
      // Optional — you can also paste the key in the admin UI.
      licenseKey: env('SHIELDAUTH_LICENSE_KEY'),
      // Shown in TOTP authenticator apps (Google Authenticator, 1Password, etc.).
      appName: 'My Strapi App',
      issuer: 'My Company',
    },
  },
});

That's the entire plugin config. Everything else (license key, encryption key) is read from environment variables — keep them out of source control.

🔐 2. Set environment variables

Add these to your .env:

# Your license key. Get it from your ShieldAuth dashboard.
# You can leave this blank and paste the key in the admin UI instead — both work.
SHIELDAUTH_LICENSE_KEY=

# Strongly recommended — encrypts TOTP secrets at rest (AES-256-GCM).
# Generate with:  openssl rand -hex 32
# ⚠️  Changing this value AFTER users enroll will invalidate every TOTP setup.
SHIELDAUTH_ENCRYPTION_KEY=

What each variable does

▶️ 3. Start Strapi and verify

npm run develop

Watch the logs for one of:

[shieldauth] License valid — plan=<your-plan> source=remote        ← all good
[shieldauth] License INVALID — No license key configured. ...       ← paste key in admin UI
[shieldauth] License backend rejected our Authorization header (...)← see Troubleshooting

If you didn't set SHIELDAUTH_LICENSE_KEY, open http://localhost:1337/admin, go to Settings → ShieldAuth → License, and paste your key. Validation runs immediately and the status panel updates.

🔑 4. Enroll your first admin

Once the license shows valid:

1. Open the admin panel and go to Settings → ShieldAuth → My MFA Devices.
2. Click Enroll TOTP, scan the QR code with your authenticator app.
3. Confirm with a 6-digit code from the app.
4. Save your recovery codes — they're shown once and you'll need them if you lose your authenticator.
5. Log out, log back in. You'll be prompted for a TOTP code after entering your password.

🪪 Seats & instanceId

Every plugin install generates a UUID (instanceId) on first startup and persists it to your Strapi DB. The ShieldAuth backend counts each unique instanceId against your seat allowance.

Important:

• The same Strapi DB = the same instanceId = one seat. Restart, redeploy, scale horizontally — all fine, no seat consumed.
• A fresh Strapi DB (new project, wiped DB, ephemeral container without persistence) generates a new instanceId and consumes a new seat. If you're stress-testing or rebuilding environments, you may hit instance-limit-exceeded.
• To free a seat: clear the license key in the admin UI, or click Release this install. Both call the backend's deactivate endpoint.

🛠️ Troubleshooting

🔄 Rotating secrets

🧹 Uninstalling cleanly

To uninstall in a way that frees the seat for reuse:

1. In the admin UI: Settings → ShieldAuth → License → Clear license key. The plugin calls the deactivate endpoint and frees your seat before clearing the local key.
2. Remove the plugin from config/plugins.ts.
3. npm uninstall strapi-plugin-shieldauth.

If you skip step 1 — for example, you delete the project without clearing the key — the seat stays attached to that orphaned instanceId. Contact ShieldAuth support to release it.
