VinCSS OVPN is an OpenVPN client designed to establish secure connections to OpenVPN servers. It features passwordless authentication through the FIDO2 protocol as an extended capability. Users can import their own connection profiles (.ovpn files) to connect to OpenVPN servers or use profiles provided by administrators for enterprise connections.

For regular users, VinCSS OVPN allows adding custom connection profiles and connecting to OpenVPN servers. Free connection profiles can be obtained from vpngate.net, offering global coverage. However, the app does not provide any free OpenVPN servers, and the reliability of free services may vary.

Enterprise users can connect to their organization's OpenVPN servers by adding provided connection profiles and completing passwordless authentication. It's worth noting that VPN functionality may be limited behind certain firewalls.
