TabAuth.in - Securely Lock Tabs using 2FA and TOTP

Secure your browser tabs with TOTP [Time based OTP] codes from your authenticator app. No passwords. No cloud. Just privacy.

TabAuth.in - Secure Your Browser Tabs with 2FA TabAuth.in is a privacy-first browser extension that protects your sensitive browser tabs by locking them behind two-factor authentication (2FA). It is designed for users who want an extra layer of security when working with confidential information in their browser. Whether you are working in a shared environment, screen-sharing, or simply stepping away from your computer, TabAuth.in ensures that selected tabs cannot be accessed without proper authentication. --- What's new in v2.1.0? • Improved Setup Experience: Faster, clearer, and easier first-time setup. • Stability Improvements: Fixed issues with the lock overlay for a smoother unlock flow. --- What TabAuth.in Does TabAuth.in allows you to lock individual browser tabs so that their contents remain inaccessible until a valid 2FA code is entered. Once a tab is protected: • The page content is blocked behind a secure authentication screen • Interaction with the tab is prevented until verification succeeds • Unauthorized users cannot view or interact with sensitive information This security is applied at the tab level, giving you precise control over what stays protected. --- Why Install TabAuth.in? Modern browsers do not provide built-in authentication for individual tabs. TabAuth.in fills this gap by offering: • Protection for sensitive dashboards, admin panels, emails, financial tools, or internal systems • Peace of mind when stepping away from your device • Extra security during presentations or screen sharing • Privacy in shared or public environments If a tab should not be visible to others without your permission, TabAuth.in is built for that exact purpose. --- Key Features • Tab-Level Locking Secure individual browser tabs instead of locking your entire browser. • Two-Factor Authentication (2FA) Access to protected tabs requires a valid 2FA code, adding a strong security layer beyond simple passwords. • Local-Only Security All authentication and configuration happen entirely on your device. • Persistent Protection Locked tabs remain protected across tab switches and browser sessions. • Minimal Permissions Only the permissions strictly required to enforce tab security are used. --- Security by Design TabAuth.in is built with a security-first mindset: • Authentication secrets are generated locally • Security configuration is stored only within the browser • No external servers are involved in authentication • No cloud sync or remote access is used • No analytics, tracking, or telemetry is implemented Because everything runs locally, your data never leaves your device. --- Privacy You Can Trust TabAuth.in is intentionally designed to collect zero user data. • No browsing history collection • No page content tracking • No personal data collection • No third-party services • No ads, trackers, or analytics All settings, authentication secrets, and state are stored locally using browser storage. Nothing is transmitted or shared. Your privacy is not a feature — it is the default. --- Important: Recovery & Access Policy For security reasons, TabAuth.in does not provide any recovery mechanism if access is lost. • If you lose your authentication setup or 2FA configuration • If you forget your credentials • If the authenticator is unavailable The only way to regain access is to uninstall the extension, which resets all local data. This is a deliberate design decision to ensure that no backdoors, recovery APIs, or bypass mechanisms exist. Only you control access. --- Completely Free — No Ads, No Subscriptions TabAuth.in is 100% free to use. • No ads • No subscriptions • No premium tiers • No hidden charges • No data monetization The goal is simple: Strong privacy and security should be accessible to everyone, not just the privileged. --- How It Works (Simple Overview) 1.
