Vault2FA - 2FA authenticator in browser geliştiren: 浪迹天涯小叮当

Vault2FA is a lightweight and privacy-focused TOTP/HOTP authenticator built for Firefox.

It generates one-time passwords (OTP) directly inside your browser, allowing you to securely access accounts protected by two-factor authentication.

Vault2FA is local-first by design. Your secrets are stored locally in the browser and never leave your device unless you explicitly enable synchronization.

Features

• 🔐 Local-first storage
  Your OTP secrets are stored locally by default. No cloud account or external service is required.
• 🔒 Optional encrypted storage
  Enable encryption for both local and sync data to protect your vault with a passphrase.
• 🔄 Optional sync sessions
  You can enable synchronization using a manually configured session ID.
  Sync is disabled by default and must be explicitly enabled.
  NOTE: it is strongly recommended to keep a local backup of your vault since Firefox Sync is designed only to sync add-on configurations, not secrets. Cloud sync therefore may have potential bugs.
  Cloud Sync is not available on Firefox mobile due to browser-side api restrictions.
• 📷 QR code scanning
  Add accounts quickly by scanning QR codes either from websites via right-click menu or uploading a local image.
• ⚡ Fast and lightweight popup
  Instantly access all your codes from the browser toolbar with a clean and responsive interface.
• ☀️🌙 Dark & Light theme supported
  Switch between themes to customize your experience.
• 📱 Full support for mobile devices
  Interface automatically scales on mobile devices. QR-Scanning page supports photos taken with camera.
• 🖊️ Auto filling 2fa input fields in pages
  Auto fill in your codes with customized URL matching rules with a in-page popup. You can disable this feature in Vault2FA's setting.
• 📥 Easy migration from popular authenticator apps
  Vault2FA supports migrating from Google Authenticator and Microsoft Authenticator.
