Overview
Simple, private, no-tracking browser 2FA authenticator
A lightweight browser extension that generates 2FA codes directly in your browser. It generates standard 6-digit TOTP codes compatible with most services. Built for privacy-conscious users. -Stores your account labels and secret keys exclusively on your device using the browser’s local storage. -Provides basic functions including code copying, account renaming, reordering, deletion, and an auto-lock feature. -Night mode or day mode The extension does not save your manual backup codes if you uninstall the browser or clear data. We recommend manual backup of secret keys in multiple locations for best security. Privacy-Focused Design: All data remains on your local device. The extension does not collect personal information, transmit data to any servers, or engage in tracking. If the extension is uninstalled or browser data is cleared, all stored accounts and secrets are permanently removed and cannot be recovered by the developer. This is an open source project.

Version 2.0 Release: -Requires passcode to access the app -Base32 pre-verification prior accepting the new secret key -Implements AES-GCM encryption for stored secrets, protected by a user-chosen master passcode (4-6 digits) with PBKDF2 key derivation. -Operates entirely offline with no network requests, no analytics, and no telemetry. -Requires only the “storage” permission to persist your accounts between browser sessions. -Requires master passcode every time a new secret key is entered. (For additional security!) We encourage users to set a master passcode prior to entering the secret keys.
