2! Authenticator: Secure 2FA in Your Browser
Stop reaching for your phone every time you log in. 2! Authenticator brings secure, Time-based One-Time Passwords (TOTP) directly to your desktop browser. Fully compatible with the export features of major mobile authenticator apps, this extension keeps you in your workflow while maintaining top-tier security.
π Why Youβll Love It
Stay in the Zone: No need to unlock your phone or wait for insecure SMS codes. Your 2FA codes are just a click away in your toolbar.
Bulk Import: Easily migrate your accounts! You can import multiple codes at once by scanning the export QR code from your mobile app.
Smart Sorting: The extension detects the website you are currently visiting and automatically suggests the correct code at the top of the list.
Universal Compatibility: Works with almost any online service that supports standard 2FA login.
π Easy Setup Options
Scan: Use your webcam to scan a QR code (supports single accounts or bulk exports).
Paste: Copy and paste a QR code image directly from your clipboard.
Drag & Drop: Simply drag a QR code image into the extension window.
Manual Entry: Type in the secret key provided by your service.
π Privacy First We believe your security is paramount.
Offline Operation: All logic is computed locally on your machine. Your codes are never sent over the internet.
Zero Data Sharing: We do not share your data with third parties.
Permissions: We only ask for permissions strictly necessary to scan codes (Camera/Active Tab) when you initiate the action.
π Premium Features (One-Time Fee: $2.99) Unlock the full potential of 2! Authenticator with a lifetime license:
AES-GCM Encryption: Lock your vault with a personal password/PIN to prevent unauthorized access.
Cloud Backup & Restore: Securely backup your vault to your preferred cloud service or hard drive. Never lose your access again.
Device Transfer: Export QR codes to move accounts to a new phone or device.
β οΈ Important Security Notes
No Password Recovery: To ensure maximum security, we cannot reset your password/PIN if you lose it. If you forget your encryption PIN, your data cannot be recovered.
Webcam Requirement: Importing multiple codes from mobile apps requires a webcam to scan the export QR code.

Does not work--can't scan QR codes even when documentation and UI says it can.

3 stars as on the free version seems I cant edit or remove an entry. not much use on the free tier. Should be a paid only plugin or add at least the basic functionality to the free version.
