You can set up Chromecast using your phone or computer instead of a physical remote

Chromecast does not require a remote to work. You control it entirely through the Google Home app on your phone or tablet, or through your computer's web browser. If your Chromecast came without a remote, or if you have lost it, you can still complete the full setup and use all features by casting from your devices.

The setup process takes about five minutes and requires only your Chromecast device, a power source, a Wi-Fi network, and the Google Home app (or a web browser). Once set up, you cast content to your TV from apps like YouTube, Netflix, Spotify, or your phone's screen — you never need to touch a physical remote.

Key Takeaways

  • read the Google Home app on your phone or tablet before you plug in your Chromecast device.
  • Plug your Chromecast into an HDMI port on your TV and a power outlet, then wait for the setup light to appear.
  • Open the Google Home app, tap the plus icon, and follow the on-screen prompts to connect your Chromecast to your Wi-Fi network.
  • Once set up, you control everything through the Google Home app or by casting from individual apps on your phone.
  • If you want physical remote control later, you can purchase a Chromecast remote separately and pair it through the Google Home app.

What you need before you start

Gather these items before you begin: your Chromecast device, a USB power cable and power adapter (usually included), an available HDMI port on your TV, and a smartphone or tablet with the Google Home app installed. The app is free and available on both iOS and Android.

You also need access to your Wi-Fi network and the password. If you do not know your Wi-Fi password, you can find it on your router (usually printed on a sticker on the back or bottom) or ask whoever manages your network. Your phone or tablet must be on the same Wi-Fi network as your Chromecast for setup to work.

Physical setup: plugging in your Chromecast

Locate an HDMI port on the back or side of your TV. Most TVs have at least two HDMI ports. Plug your Chromecast into one of them — it looks like a small stick or puck with an HDMI connector on one end. Push it in firmly until it clicks.

Next, connect the USB power cable to the power adapter, then plug the adapter into a wall outlet or power strip near your TV. Your Chromecast will light up. Within 10 to 15 seconds, you should see a white or colored light on the device, and your TV screen may show a setup code or the Google Chromecast logo. This means the device is ready to pair.

If your TV does not show anything, make sure the HDMI input is set to the port where you plugged in the Chromecast. Use your TV remote to switch inputs until you see the Chromecast screen.

Connecting through the Google Home app on your phone

Open the Google Home app on your phone or tablet. If you do not have it, read it from the Google Play Store (Android) or the Apple App Store (iOS). Sign in with your Google account — the same one you use for Gmail or YouTube.

Tap the plus icon (usually in the top left corner) and select "Set up device." Choose "Set up a new device" and then "Chromecast." The app will search for nearby Chromecast devices. When it finds yours, tap it to select it.

The app will ask you to confirm the setup code shown on your TV screen. Look at your TV and read the four-digit code, then enter it in the app. This confirms that your phone is controlling the correct device. Tap "Yes" to continue.

Connecting to your Wi-Fi network

The app will now show a list of available Wi-Fi networks. Find your network name in the list and tap it. Enter your Wi-Fi password when prompted. Make sure you type it correctly — passwords are case-sensitive, meaning capital and lowercase letters are different.

The app will connect your Chromecast to your network. This usually takes 30 seconds to two minutes. You will see a progress bar on your screen. Do not unplug your Chromecast or close the app during this step.

Once the connection is complete, the app will ask you to name your Chromecast (for example, "Living Room TV" or "Bedroom Chromecast"). This name helps you identify the device if you have multiple Chromecasts in your home. You can change it later if you want.

Finishing setup and testing your Chromecast

The app will ask whether you want to enable features like Google Assistant voice control or whether you want to receive notifications. You can turn these on or off based on your preference — they are not required to use Chromecast.

Once setup is complete, your Chromecast is ready to use. Open any app that supports casting — YouTube, Netflix, Spotify, or Google Photos are common examples. Look for the cast icon (it looks like a rectangle with curved lines in the corner) and tap it. Select your Chromecast from the list, and the content will play on your TV.

You can also cast your entire phone or computer screen to your TV. On Android, go to Settings, then Display, then Cast. On iPhone or iPad, swipe down from the top right corner to open Control Center, tap Screen Mirroring, and select your Chromecast. On a computer, open Chrome, click the three-dot menu, select "Cast," and choose your device.

What to do if setup fails

If your Chromecast does not appear in the Google Home app, make sure your phone is on the same Wi-Fi network as the Chromecast. The device cannot connect to a different network than your phone during setup. Also check that your phone's Bluetooth is turned on — the app uses Bluetooth to communicate with the device during pairing.

If the setup code does not match, unplug your Chromecast, wait 10 seconds, and plug it back in. A new code will appear on your TV screen. Try again with the new code.

If you cannot connect to Wi-Fi, double-check your password. A common mistake is confusing the Wi-Fi password with your Google account password — they are different. If you are still stuck, restart your router by unplugging it for 30 seconds, then plugging it back in.

Adding a remote later if you want one

Chromecast works perfectly without a physical remote, but if you decide you want one later, Google sells an official Chromecast remote separately. It connects through the Google Home app — open the app, go to your Chromecast settings, and select "Remote." Follow the pairing instructions on screen.

Third-party remotes designed for Chromecast are also available from other manufacturers. Check the product description to make sure it is compatible with your specific Chromecast model before you purchase.

Frequently Asked Questions

Can I set up Chromecast without a smartphone?

Yes. Open a web browser on your computer and go to chromecast.com/setup. Follow the same steps as the mobile app — you will see the setup code on your TV and enter it in the browser. Your computer must be on the same Wi-Fi network as the Chromecast.

What if I forget my Wi-Fi password?

Check your router — the password is usually printed on a sticker on the back or bottom. If you cannot find it, you can reset your router to factory settings by holding the reset button for 10 seconds, but this will erase all your Wi-Fi settings and you will need to set up your network again.

Can multiple people control the same Chromecast?

Yes. Anyone on the same Wi-Fi network can cast to your Chromecast using their phone or computer. You can also add other people to your Chromecast in the Google Home app so they can control it from their own devices.

Do I need a Google account to use Chromecast?

Yes, you need a Google account to set up Chromecast through the Google Home app. Once it is set up, you can cast from apps without signing in again, but the initial setup requires a Google account.

What happens if my Wi-Fi goes down?

Your Chromecast will lose connection to the internet and you will not be able to cast to it until your Wi-Fi is back online. The device itself does not need internet to display content that is already playing, but it cannot receive new casting commands without a network connection.
