When you suspect a breach, every second counts. API Kill Switch gives you the tools to act immediately.

💀

One-Click Kill All

Click the big red button, confirm with your PIN, and every active API key gets revoked in parallel. Done in seconds.

✅

Verified Dead

After revocation, we verify each key is actually dead by hitting the provider's API. No false sense of security.

🔒

Encrypted Local Storage

Your API keys never leave your computer. Encrypted with AES-256-GCM and stored locally — not on any server, ever.

🔐

PIN Protection

4-digit PIN required to open the app and before every kill action. Fast and reliable — works instantly, every time.

FAQ

Questions? Answered.

Are my API keys safe?

Your keys are encrypted using AES-256-GCM with a key derived from your PIN. They're stored locally in your browser and never transmitted to any server — only to the provider's revocation endpoint when you choose to kill them.

What happens when I hit Kill All?

Every active key is revoked simultaneously across all providers. After revocation, each key is verified dead by checking the provider's API. You'll see ✅ (dead), ⚠️ (revoked but unverified), or ❌ (failed) for each key.

Can I revoke a single key?

Yes. Hover over any key card and click the Kill button. Enter your PIN to confirm, and that single key is revoked and verified.

What if I accidentally kill a key?

Revoked keys cannot be un-revoked through our app — this is by design for security. You'll need to generate a new key from the provider directly. The audit log keeps a full record of everything.

Why a PIN?

In an emergency, you need speed and reliability. A 4-digit PIN always works — fast, simple, no hardware dependency.

Can I add my own API provider?

Yes. The Custom provider lets you specify any revocation URL, HTTP method (DELETE/POST/PUT), and authorization header. If it has an API, you can kill it.
