Overview
Block distracting domains and require a hardware security key to temporarily unlock them.
Focus Guard is a friction-based self-discipline tool for Chrome/Brave. ### What It Does - Block distracting websites (social media, news sites, games, etc.) - Require hardware security key tap (YubiKey, FIDO2) to unlock them - Auto-lock after a configurable timer (default: 1 hour) - Prevent removing domains or changing settings without key verification ### Why It Works Willpower fails. But friction succeeds. By requiring a physical object (your security key) to unlock sites, you add a deliberate moment of friction that breaks the impulsive loop. Most times, that friction is enough. You move on. On rare occasions when you really need access, you can unlock—but the timer ensures you're back to focus mode when it expires. ### Why Security Key? Standard passwords are weak (you reuse them, they're easy to bypass). A hardware security key cannot be phished, copied, or guessed. It must be in your hand, at your desk, right now. That physical constraint is the whole point. ### Privacy & Trust - No server, no accounts, no phone home - All blocking rules, settings, and unlock sessions stay on your device - No sync across devices (by design—friction only works if you own the hardware key) - Open source, transparent, auditable - No telemetry, no ads, no selling data ### How to Use 1. Register your hardware security key when you first open the extension 2. Add domains to your blocklist 3. Try visiting one—you'll see a challenge screen asking for your key 4. Tap the key to unlock for the configured duration 5. When time expires, the site is blocked again ### Supported Keys YubiKey 5 series, Titan Security Keys, Nitrokey, and any FIDO2/WebAuthn cross-platform (roaming) authenticator. Security keys must have user verification (PIN or biometric).
