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 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.
