Overview Product summary Review the store description, core capabilities, and common use cases.
Open Two-Factor Authenticator aims to provide an open-source two-factor authentication to browsers and Android devices with synced storage.
By using this extension, you can have your encrypted keys stored in the browser's synced storage. This allows you to sync them across multiple devices. This extension uses the public key/private key method to encrypt stored data (SHA-256).
Currently, Open Two-Factor Authenticator supports Firefox on Desktop, Firefox on Android, Chrome, Edge, and Opera browsers. Standalone Android implantation is still in progress.
Features:
1. Stores secrets securely using AES-CBC encryption.
2. Does not store passwords

AI product read Open-source TOTP (Time-based One-Time Password) authenticator that stores and generates 2FA codes with AES-CBC encryption in the browser's synced storage Provides a secure, open-source, cross-device 2FA authenticator for browsers, eliminating the need for a phone-based authenticator app while keeping TOTP secrets encrypted and synced across devices
1. User clicks extension popup and enters a Master Password (used for local AES-CBC encryption, not an account). 2. Existing TOTP entries are decrypted and displayed with service icons. 3. User selects an entry to view the current TOTP code with a countdown timer. 4. User can copy the code to clipboard. 5. To add new entries, user clicks the Plus button, enters the TOTP secret (or scans a QR code), sets a name/password/digits/period/icon, and saves. The secret is encrypted and stored in Chrome's synced storage.
Store TOTP secrets encrypted with AES-CBC using SHA-256 derived key from a master password Generate and display time-based one-time passwords with countdown progress bar Scan QR codes to quickly add new TOTP entries Copy TOTP tokens to clipboard with one click Custom number of digits (6 or 8) and custom validation period Drag-and-drop reordering of credential entries
Target users Users who need browser-based 2FA/TOTP code management / Users who want cross-device sync of TOTP secrets without relying on a phone / Privacy-conscious users who prefer open-source authenticator solutions The heuristic false-positive on PayPal payment integration was resolved by reading source files — PayPal is just a service icon option, not a payment platform The 'authentication' keyword match was a false positive for login detection — the product IS an authenticator, but does not require the user to log in to any service Monetization
