TabAuth.in - Securely Lock Tabs using TOTP

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 v3.0.0: Redesigned Lock Overlay • Completely revamped lock screen experience • Live clock with date & time • Recovery code entry directly from the lock screen

Lock Tabs Instantly • New keyboard shortcut: Ctrl + Shift + L to lock the current tab in a single keystroke

All-New Dashboard & Settings Everything you need, secured in one place: • User statistics • Authenticator app reconfiguration via QR code • Backup & recovery codes • View and manage all currently locked tabs, with the ability to unlock them

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.

• Recovery Codes Use these Backup & Recovery codes in case you lose access to your authenticator app

• Centralized Dashboard Use the secure centralized dashboard to reconfigure your authenticator app, recover access if you lose your device, download backup recovery codes, and view or unlock all currently locked tabs from one place.

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.

Backup & Recovery Codes To help prevent accidental lockouts, TabAuth provides 10 Backup & Recovery Codes from the dashboard. These codes can be used to access the secure dashboard if your authenticator app or device is unavailable.

Important: • The backup codes are displayed only once when they are generated. • You can download them as a .txt file for safekeeping. • Once dismissed, the codes cannot be viewed again. If you still have access to the dashboard, you can only generate a new set, which permanently invalidates the previous codes.

Secure Dashboard Access All account management is performed through the secure dashboard, including: • Reconfiguring your authenticator app • Generating new Backup & Recovery Codes • Viewing and unlocking locked tabs

The dashboard can typically be opened by right-clicking the TabAuth extension icon and selecting "Options." The exact steps may vary slightly depending on your browser and device.

Access to the dashboard requires either: • A valid Authenticator (2FA) code, or • A valid Backup & Recovery Code

If You Lose Access If you lose both your authenticator app and all Backup & Recovery Codes, there is no recovery mechanism.

The only way to regain access is to uninstall the extension, which permanently resets all locally stored data.

This is a deliberate design decision. TabAuth contains no backdoors, cloud recovery services, recovery APIs, or bypass mechanisms - only you control access to your locked tabs.

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. Install TabAuth.in
2. Complete the one-time setup and enable 2FA
3. Choose which tabs to protect
4. When a protected tab is accessed, authentication is required
5. Without a valid 2FA code, the tab remains locked

That’s it — no accounts, no sign-ups, no servers.
