AuthentQ

AuthentQ — two-factor authentication by Nesqual Tech

AuthentQ generates the six- and eight-digit verification codes that protect your accounts with two-factor authentication (2FA). It works with virtually every service that offers authenticator-app sign-in: Google, Microsoft, GitHub, Amazon, banks, social networks, and thousands more.

Private by design
Your authentication secrets are stored only on this device, protected by the Android Keystore. AuthentQ collects no data, requires no account, shows no ads, and makes no network connections. What happens on your phone stays on your phone.

Everything you need
• Add accounts in seconds — scan the QR code shown by any service, or type the key manually
• Time-based (TOTP) and counter-based (HOTP) codes, RFC 6238 / RFC 4226 compliant
• SHA-1, SHA-256 and SHA-512 algorithms, 6 or 8 digit codes, custom time periods
• Clear countdown ring shows exactly when each code refreshes
• One-tap copy with haptic confirmation

Built for security
• App lock with fingerprint, face unlock, or your device passcode
• Optional hidden codes — masked in the list until you tap to reveal
• Screenshot and screen-recording blocking
• Duplicate detection when adding accounts
• Removal warnings so you never lock yourself out by accident

Designed to be used
A clean, fast interface with day and night themes, search for large account lists, and instant code access the moment you open the app. No clutter, no upsells.

Important
Codes are stored only on your device. If you remove an account or lose your phone, AuthentQ cannot recover it — always keep the backup codes your services provide when you enable 2FA.

AuthentQ is built and maintained by Nesqual Tech SRL, an EU-based software studio. GDPR compliant.
