Using the free VPN in Opera

After downloading the browser, enabling VPN is easy. Go to “Settings” (or “Go to the Browser Setting” ), choose “Privacy & Security” and then toggle the free VPN. An icon labeled “VPN” will appear in the browser, from which you can toggle VPN on and off, and choose a location.

 Users can also let the Opera browser intelligently select the optimal server location based on factors such as network speed, latency, location and server capacity. When in automatic location mode, browsing via the VPN is always at maximum available speed.
