WireGuard protocol gives you lower latency which is useful for gaming. It can also provide higher peak speeds when connected to a VPN server closer to your physical location. See differences between VPN Vault's current protocol and WireGuard protocol.
To enable WireGuard protocol on VPN Vault:
- Go to 'User' tab
- Tap on the Gear icon at the top right corner to go to Settings
- Toggle the 'Activate WireGuard Protocol' button to enable WireGuard protocol
- You may be prompted with a message to confirm. Tap 'Yes' and you are good to go.
Do note that by switching protocols, you may face some connection issues and not all countries are supported.
