About Authenticator Extension
Manage all your two-factor authentication (2FA) codes simply, quickly, and with maximum security, right from your browser. Designed with privacy in mind, this extension encrypts all your data locally with a single master password. Your secrets never leave your device.
Key Features:
- Maximum Security: Your vault is protected by robust end-to-end encryption (AES-GCM), derived from your master password (PBKDF2). No data is ever sent to external servers.
- Smart Synchronization: Enable sync to securely access your encrypted vault across all browsers logged into your Google account.
- QR Code Management: Add new accounts by importing a screenshot, by directly scanning a QR code from your screen, or by using the precision targeting mode — select your screen, get a 5-second countdown to switch to the right app, then draw a rectangle around the QR code for accurate detection. You can also view and re-download the QR code for any existing account later.
- Enhanced Productivity: Copy your codes with a single click or by using the Alt+C keyboard shortcut. Effortlessly organize your accounts with a dynamic drag-and-drop interface and a powerful search function for faster access.
- Full Control: Compatible with both TOTP (time-based) and HOTP (counter-based) standards. Customize algorithms (SHA-1, SHA-256), digit count, and period.
- Backup and Restore: Export your encrypted vault for secure backups, and easily import it on a new device.
- Customizable Interface: Choose between a light, dark, or system-synced theme. The extension is also multilingual (French, English, German, Portuguese).
