## Description

FTCOS Authenticator is a hardware-backed two-factor authentication app designed for FEITIAN security keys.

Add an account by scanning a service&#39;s QR code or entering the secret manually<br>2. Hold your FEITIAN security key near your device<br>3. The app reads the current OTP code directly from the key<br>4. Your secret remains safely stored in the hardware key at all times
