How to stream with ExpressVPN

A VPN (Virtual Private Network) is an app that encrypts your internet connection and masks your IP address, allowing you to stream securely and bypass restrictions.

- Increase Privacy: A VPN protects your data on non-secure public Wi-Fi networks by creating an encrypted tunnel, safeguarding your personal information while you stream.
