ELI5 Explanation: Your laptop and phone act like detective partners. To log in on your laptop using your phone, the laptop shows a secret code (QR code). Your phone scans this code to tell the laptop, "It's really me!"
2.Core Concepts:
   - QR Code: A digital shortcut that contains information. The laptop displays it, and the phone reads it with its camera.
   - Authentication:The QR code helps your phone authenticate your login.
3.Details on Core Concepts:
   - QR Code: Used for quick interactions like ticket scanning and secure logins.
   - Authentication: Ensures only authorized users can access accounts.
4.Examples of Smooth Auth Flows:
   - WhatsApp Web: Lets you use WhatsApp on your computer by scanning a QR code with your phone.
   - Apple's Continuity: Allows seamless transitions between devices without re-logging in.
In summary, scanning a QR code with your phone to log into your laptop streamlines the login process securely and conveniently.
