About Auto OTP Authenticator

English Auto OTP Authenticator is a lightweight, privacy-focused TOTP (Time-based One-Time Password) manager for your browser. It generates one-time codes, helps you organize accounts, and can fill them into common 2FA / verification forms—so you don’t have to reach for your phone for every login. After setup, TOTP codes are computed entirely on your device using the Web Crypto API. Secrets stay in your browser profile by default. There are no analytics servers, no telemetry, and no tracking from this extension. What it supports TOTP codes (RFC 6238) — typically 6 or 8 digits, 30-second (or custom) steps, HMAC-SHA1 or HMAC-SHA-256 Automatic detection & fill — supports single-field and multi-box OTP layouts Domain-aware accounts — matches and prioritizes accounts per website Popup workflow — search, filter, copy, delete, last-used priority Keyboard shortcuts — copy/fill without opening popup QR & otpauth — scan from page (including iframes) or import from image Import & export — JSON backup/restore Appearance — light/dark/system theme Optional Chrome sync — stores data in Google sync (optional) Languages — English, Turkish, German, Spanish, Italian Privacy & security Default: chrome.storage.local Codes generated locally No backend servers Export backups manually Not a replacement for hardware keys (e.g., YubiKey) Turkish (Türkçe) Auto OTP Authenticator, tarayıcınızda kullanabileceğiniz hafif ve gizlilik odaklı bir TOTP (zaman tabanlı tek kullanımlık şifre) yöneticisidir.
