━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
❓ WHY USE LOCKSY?
Ever stepped away from your computer and worried about someone accessing your open tabs? Or work in a shared environment where sensitive information could be compromised? Locksy solves these real-world problems:
✅ COMMON SCENARIOS:
• You're at a coffee shop and need to step away - lock your banking tabs instantly
• Working from a shared computer at work or library - protect your personal accounts
• Family members use the same computer - keep your private browsing secure
• Presenting your screen in meetings - prevent accidental exposure of sensitive tabs
• Managing multiple accounts - add extra security layer to important sessions
• Browser stays open 24/7 - protect tabs even when you're away
🎯 THE PROBLEM:
Simply closing tabs isn't always practical when you have multiple sessions, complex workflows, or need to maintain your browsing state. Browser passwords don't protect already-open tabs, and Windows/Mac lock screens don't prevent someone with access from viewing your browser content.
💡 THE SOLUTION:
Locksy adds a password-protected lock screen to individual tabs or entire domains. Even if someone accesses your browser, they'll need your password to view locked content. It's like having a safe for your most sensitive browser tabs.
