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