Vault2FA por 浪迹天涯小叮当

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

It generates time-based one-time passwords (TOTP) 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 TOTP secrets are stored locally by default. No cloud account or external service is required.
• 🔒 Optional encrypted storage
  Enable local encryption 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 keys. 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 from websites.
• ⚡ 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 scanning via camera.

Privacy

Vault2FA is designed with privacy in mind:
Secrets are stored locally by default.
Synchronization uses Firefox Sync and is optional and user-controlled.
No tracking, analytics, or external telemetry.
