How does Netflix block you from password sharing? When Netflix announced a password-sharing crackdown, most people thought they’d require logins or two-factor codes. But the tech is way more subtle and smarter. Netflix uses a combination of device fingerprinting and home network analysis. That means they track: -What device you’re using -Your IP address -Your connection type -Even the way your device behaves when streaming They create a digital fingerprint so if you’re suddenly watching from a new Smart TV 800 miles away on a different Wi-Fi? That raises a flag. They also use heuristics pattern detection. Maybe you log in from one place 90% of the time… but your roommate logs in from 5 cities in 3 months? That’s suspicious. But here’s the interesting part: Instead of locking you out, they “nudge” you. Netflix lets you add “extra members” or verify new devices because they know too much friction means canceled subscriptions. #tech #techexplained #technology #stem
