Q-Authenticator

Q-Authenticator is a secure, offline two-factor authentication app built by Quatech. Generate time-based one-time passwords (TOTP) for all your accounts — Gmail, GitHub, Coinbase, Microsoft, and any service that supports 2FA — without ever needing an internet connection.




KEY FEATURES
• 100% offline — works with no Wi-Fi or mobile data
• AES-256-GCM encrypted vault — your secrets are protected by a PIN only you know
• QR code scanner — add accounts instantly by scanning a setup QR code • Manual entry — enter secret keys directly if needed
• No ads, no tracking, no data collection
• No account or sign-up required




HOW IT WORKS
Q-Authenticator stores your TOTP secrets encrypted on your device. When you open the app and enter your PIN, it decrypts your accounts and generates fresh 6-digit codes that rotate every 30 seconds — just like Google Authenticator or Authy, but with no cloud sync and no data leaving your device. PRIVACY All data stays on your device. No analytics, no crash reporting, no third-party SDKs. Camera permission is used only for QR code scanning and is never accessed otherwise.
