Chrome Extension «2FA Authenticator — FB Tools»
We take your privacy seriously. This extension is built with a data-minimization principle — we do not collect, transmit, or sell any user data.
The extension does not collect any personal information, usage data, analytics, or telemetry. We do not track your activity or create user profiles.
All account data (names and TOTP secrets) is stored exclusively on your device using chrome.storage.local. Data never leaves your browser.
The extension makes zero network requests. TOTP codes are generated entirely locally using the Web Crypto API. No internet connection is required.
The extension sends anonymous, aggregated event counts (e.g. popup_opened, code_copied, account_added) to Google Analytics 4 via Measurement Protocol. Identification uses only a random UUID generated on-device. Never transmitted: account names, secret keys, TOTP codes, website hostnames, clipboard contents. Disable in Settings → Privacy. The 2fa.fb.tools website also uses GA4 for basic visit metrics.
