Ready to flip the switch on a little more online privacy? Fortunately, turning on a VPN is easier than remembering another password. In most cases, all it takes is opening your VPN app and tapping or clicking Connect.

Whether you want to know how to turn on a VPN for the first time or simply reconnect after disabling it, this quick guide covers how to enable a VPN, check your connection, and troubleshoot a VPN that refuses to cooperate.

How to Turn On a VPN

No complicated tech skills required. If your VPN is already installed and configured, getting connected usually takes just a few steps.

Start by opening your VPN app and selecting your preferred server. For detailed instructions, find your device below.

The process is pretty much the same whether you’re turning on a VPN on an iPhone, Android phone, Mac, or Windows PC.

How to Turn On a VPN in Your Device Settings

If you’ve already configured a VPN directly through your device, you can turn it on without opening your VPN provider’s app. The exact steps vary by operating system, but you’ll need to select an existing VPN connection and connect.

How to Turn On a VPN on iPhone or iPad

  1. Open Settings.
  2. Go to General > VPN & Device Management > VPN.
  3. Select the VPN configuration you want to use if you have more than one.
  4. Turn on the VPN or tap the option to connect.
  5. Check for the VPN indicator or return to the VPN settings to confirm the connection is active.

How to Turn On a VPN on Android

  1. Open Settings.
  2. Go to Network & Internet > VPN. Depending on your device, the VPN menu may appear under Connections, More connections, or a similar network setting.
  3. Select the VPN you want to use.
  4. Enter your login information if prompted.
  5. Tap Connect and check the connection status to make sure the VPN is active.

How to Turn On a VPN on Windows

  1. Open Settings.
  2. Select Network & internet > VPN.
  3. Find the VPN connection you want to use.
  4. Select it and click Connect.
  5. Enter your sign-in information if prompted and wait for Windows to show that the VPN is connected.

How to Turn On a VPN on Mac

  1. Open System Settings.
  2. Select VPN in the sidebar.
  3. Find the VPN configuration you want to use.
  4. Turn on the VPN connection.
  5. Check the connection status to confirm that your Mac is connected to the VPN.

How to Turn On a VPN on Linux

The process on Linux varies depending on your distribution and how the VPN was configured. If your VPN is set up through your system’s network settings, open the network or VPN menu, select the configured connection, and connect.

Some VPN services also provide Linux apps or command-line tools. In those cases, follow your provider’s instructions for connecting through its software.

What Happens When You Turn On a VPN?

When you activate your VPN, it creates an encrypted connection between your device and a VPN server. Your internet traffic travels through this connection before reaching websites and online services.

The VPN server’s IP address is then visible to websites instead of your regular public IP address. This can provide additional privacy while you’re browsing, especially when using networks you don’t completely trust.

Do You Need to Close Your Apps Before Turning On a VPN?

You don’t necessarily have to close everything before turning on your VPN. In most cases, your open apps can stay open while the VPN establishes its connection.

However, an app or website that’s already connected may not immediately recognize your new VPN connection or IP address. Refreshing the page, reopening the app, or starting a new session can help if something doesn’t look or work as expected.

You may notice this most when using services that pay attention to your IP address or location. If an app was open before you connected to the VPN, give it a quick refresh after the connection is established.

What If Your VPN Won’t Turn On?

Tapping Connect and getting nowhere? Your VPN may just need a little attention before it’s ready to cooperate.

Start by checking your regular internet connection. If you’re online but the VPN is not connecting, close and reopen the VPN app and try again. You can also switch to another VPN server or restart your device.

If you’re using a manually configured VPN, double-check your login information and VPN configuration details. An incorrect server address, protocol, or other connection setting can prevent the VPN from connecting.

If your VPN still isn’t working, check for app updates and review your VPN configuration. For more troubleshooting tips, check out our guide on what to do when your VPN is not connecting.

How Do You Know Your VPN Is On?

Your VPN app should show that you’re connected, but you can also check your VPN IP address to confirm the connection. Your current IP address should reflect the VPN server rather than your regular public IP address.

For an additional check, you can run a DNS leak test to make sure your DNS requests aren’t being sent outside the VPN connection.

You may also see a VPN indicator or icon on your device while the connection is active.

Ready to Turn Your VPN Off?

Now you’re all set. You know how to turn on your VPN, check your connection, and troubleshoot a few common issues along the way. Once connected, your VPN can keep working in the background while you browse, stream, or go about your usual online routine.

And when you need to disconnect VPN, simply open your app and disconnect. You can always reconnect when you’re ready.

FAQs

Can I Leave My VPN On All the Time?

Yes, you can generally leave your VPN connected if you want ongoing VPN protection. There may also be times when it makes sense to turn your VPN off temporarily, especially if it’s affecting your connection speed or how certain websites and apps work.

Why Does My VPN Keep Turning Off?

An unstable internet connection, VPN app settings, battery-saving features, or connection problems with a particular server can cause a VPN to disconnect. Try reconnecting or switching servers, and check your app settings if the problem continues.

Do I Need a VPN App to Turn On a VPN?

Not always. Many devices allow you to manually configure a VPN through their built-in settings, although you’ll need the configuration details for the VPN service you’re using.

Can a VPN Turn On Automatically?

Yes. Some VPN apps offer an auto-connect feature that can turn on the VPN when your device starts or when you connect to certain networks. Check your VPN app’s settings to see which automatic connection options your provider offers.

Can I Turn On a VPN Without Wi-Fi?

Yes. A VPN can generally work over a mobile data connection as well as Wi-Fi. You still need an active internet connection because the VPN needs to connect your device to a VPN server.

What Happens If I Change Networks While My VPN Is On?

Your VPN may briefly lose its connection when you move from one network to another, such as switching from Wi-Fi to mobile data. Depending on your VPN app and settings, it may reconnect automatically or require you to connect again.
