  • Active ExpressVPN subscription
  • ExpressVPN app installed on your device
  • Administrative privileges on your device
  • Basic understanding of VPN protocols

Step-by-Step Instructions

1

Launch ExpressVPN application

Open the ExpressVPN app on your device. If you're not already signed in, enter your credentials to access the main dashboard. Ensure you're disconnected from any VPN server before changing protocol settings.
Close other VPN applications to avoid conflicts during protocol changes.
2

Access the Settings menu

Click on the hamburger menu (three horizontal lines) located in the top-left corner of the app. From the dropdown menu, select Settings or Preferences depending on your operating system.
3

Navigate to Protocol options

In the Settings window, look for the Protocol or Connection section. This is typically found under the Advanced or General tab. Click on Protocol to expand the available options.
On mobile devices, you may need to scroll down to find the Protocol section.
4

Select your preferred protocol

Choose from the available protocol options:
  • Automatic - Recommended for most users, automatically selects the best protocol
  • Lightway UDP/TCP - ExpressVPN's proprietary protocol for speed and security
  • OpenVPN UDP/TCP - Industry standard with high security
  • IKEv2 - Good for mobile devices with frequent network switching
Click on your desired protocol to select it.
Lightway is generally the fastest option, while OpenVPN TCP works better on restricted networks.
5

Configure additional protocol settings

If available for your selected protocol, configure additional settings such as:
  • Port selection for custom port numbers
  • Cipher settings for encryption preferences
  • DNS settings for custom DNS servers
Most users can leave these at default settings unless specific requirements exist.
Only modify advanced settings if you understand their implications on security and performance.
6

Save and apply changes

Click Save or Apply to confirm your protocol selection. The app may briefly disconnect if you were connected to a server. Close the Settings window to return to the main interface.
7

Test the new protocol connection

Connect to a VPN server to test your new protocol settings. Choose a server location and click the Connect button. Verify the connection is successful and check your IP address to confirm the VPN is working properly with the new protocol.
Test connection speed and stability with the new protocol to ensure it meets your needs.

Common Issues & Troubleshooting

Protocol options are grayed out or unavailable

Disconnect from the VPN server first, then try accessing protocol settings. Some protocols may not be available on certain platforms or regions.

Connection fails after changing protocol

Switch back to Automatic protocol selection or try a different server location. Check if your network blocks the selected protocol and consider using OpenVPN TCP for restrictive networks.

Slower speeds after protocol change

Try different protocols to compare performance. Lightway UDP typically offers the best speeds. Clear the app cache and restart the application if performance issues persist.

App crashes when changing protocol settings

Update the ExpressVPN app to the latest version. Restart your device and try again. If the issue persists, contact ExpressVPN support or reinstall the application.
