Is the VPN service offered by Opera browser functional?

Yes, Opera browser provides a functional VPN service. The built-in VPN feature in Opera is designed to enhance privacy and security for its users by encrypting their browser traffic and masking their IP addresses. This service allows users to browse the web with increased anonymity, potentially bypassing geo-restrictions and reducing online tracking. It's a free and unlimited service that doesn't require an additional subscription or payment, making it an attractive option for users who wish to improve their online privacy without investing in a separate VPN solution. However, it's important to note that this VPN only encrypts traffic within the Opera browser itself, rather than the entire device's internet connection like full-featured, standalone VPN applications.
