FactorCat is a modern authenticator that replaces the code-copying ritual with a single tap. How it works: Install the browser extension on your computer. When you hit a login page that needs a code, FactorCat sends a push notification to your phone. Tap approve, confirm with Face ID or fingerprint, and the code fills in automatically. No switching apps. No squinting at timers. No mistyped digits. Security you can trust: Your TOTP secrets are stored on your device, encrypted and protected by biometrics. FactorCat never holds your passwords — MFA and passwords stay separate by design, so there's no single point of failure for your online identity. Two vault types: • Cloud Vault — cloud-managed keys for easy recovery. Great for getting started with MFA or for low-risk accounts. FactorCat can generate codes on your behalf when your phone is offline. • Locked Vault — zero-trust encryption using a model trusted by leading security products. You hold the keys. FactorCat cannot read your secrets. Backup via encrypted cloud blobs recoverable only with your emergency kit. Getting started takes 2 minutes: 1. Download FactorCat 2. Add your first token (scan a QR or let the browser extension capture it) 3. Pair with the extension via one QR scan 4. Done — your next login fills itself in Also works standalone. Use FactorCat as a regular authenticator with no account or extension required. When you're ready for auto-fill, pair up anytime. Free to use. No ads. No tracking.
