Store your OTP secrets in hardware, not on your phone. FTCOS Authenticator works with FEITIAN security keys via NFC — your codes stay safe even if your device is lost. FTCOS Authenticator is a hardware-backed two-factor authentication app designed for FEITIAN security keys. Unlike traditional authenticator apps that store secrets on your device, FTCOS Authenticator writes OTP secrets directly to a FEITIAN security key and reads codes over secure NFC communication — your secrets never touch your phone's storage. Key Features: • Hardware-backed security — OTP secrets are stored in the security key, not on your device • NFC communication — simply tap your FEITIAN security key to read codes • TOTP & HOTP support — compatible with most online services (6 or 8 digits) • Quick account setup — scan a QR code or paste an otpauth:// URI • Touch-to-generate — optional extra protection requiring physical key confirmation • Dark & Light theme — follows your system preference • One-tap copy — tap any code to copy it to your clipboard How It Works: 1. Add an account by scanning a service's QR code or entering the secret manually 2. Hold your FEITIAN security key near your device 3. The app reads the current OTP code directly from the key 4. Your secret remains safely stored in the hardware key at all times Requirements: • A FEITIAN security key with OATH applet support • NFC-capable device (iOS 15.6+) Privacy: FTCOS Authenticator does not collect, transmit, or store any personal data. All authentication secrets remain exclusively in your FEITIAN security key.
