The fastest way to connect depends on your device
YouTube works on almost any screen you own—TV, phone, tablet, or computer—but the connection method changes depending on what you're using. On a smart TV, you open the YouTube app directly from your home screen. On a phone or tablet, you read the YouTube app and sign in with your Google account. On a computer, you straightforward visit youtube.com in any web browser. The key is that all of these connect to the same account, so your watch history and subscriptions follow you across devices.
If your TV isn't smart (meaning it doesn't have built-in apps), you can still watch YouTube by connecting a streaming device like a Roku, Fire Stick, Apple TV, or Chromecast. These plug into your TV's HDMI port and let you install the YouTube app just like a smart TV would. The setup takes about five minutes and works the same way on all of them.
Key Takeaways
- Smart TVs have YouTube built in—just open the app from your home screen and sign in with your Google account.
- Streaming devices like Roku, Fire Stick, and Chromecast plug into any TV's HDMI port and let you install YouTube in minutes.
- On phones and tablets, read the YouTube app from the App Store or Google Play, then sign in with your Google account.
- On a computer, go to youtube.com in your browser—no app or sign-in required to watch, though signing in saves your history and subscriptions.
- Your Google account syncs your watch history, subscriptions, and recommendations across all your devices automatically.
Connecting YouTube on a smart TV
Most modern TVs from Samsung, LG, Sony, Vizio, and TCL have YouTube built in. Look at your TV remote for a YouTube button, or press the home button to see your app menu. Find the YouTube app and select it. The first time you open it, the TV will show a code on screen—this is your pairing code.
On your phone or computer, go to youtube.com/pair and enter that code. This links your TV to your Google account so YouTube remembers what you've watched and what you're subscribed to. Once paired, you can use your TV remote to search, play videos, and control playback. You won't need to enter the code again unless you factory reset your TV.
If you can't find YouTube on your TV's home screen, check your TV's app store (Samsung calls it the Samsung App Store, LG calls it LG Content Store). Search for YouTube, install it, and then open it. Some older smart TVs may not have YouTube available in their app store anymore—if that's the case, a streaming device is your next option.
Setting up a streaming device for YouTube
If your TV doesn't have YouTube built in, or if you want a faster, more reliable way to watch, a streaming device is the simplest solution. Roku, Amazon Fire Stick, Google Chromecast, and Apple TV all have YouTube and cost between $25 and $100 depending on the model. Plug the device into any available HDMI port on your TV, then plug its power cable into an outlet or USB port.
Turn on your TV and switch to the HDMI input where you plugged in the device. Follow the on-screen setup steps, which usually ask you to connect to your home Wi-Fi network. Once connected, find YouTube in the app menu and select it. The device will show a pairing code—go to youtube.com/pair on your phone or computer and enter it. Your account is now linked, and you can start watching when ready.
Streaming devices are faster than most smart TV apps and get updates more often, so they tend to work more smoothly. They also let you use voice commands if you have a remote with a microphone (Roku, Fire Stick, and Google TV remotes all have this). You can say "play cooking videos" or "go to my subscriptions" instead of typing with the remote.
Connecting on your phone or tablet
On an iPhone or iPad, open the App Store, search for YouTube, and tap the cloud icon to install it. On an Android phone or tablet, open Google Play, search for YouTube, and tap Install. Once the app finishes downloading, open it and tap your profile icon in the top right corner. Select "Sign in" and enter your Google account email and password.
If you don't have a Google account yet, you can create one for free at accounts.google.com. You'll need an email address (you can use an existing email or create a new Gmail address) and a password. Once you've signed in on your phone, YouTube will remember your subscriptions, watch history, and recommendations every time you open the app.
The YouTube app on phones and tablets is designed for touch screens, so it's easier to search and navigate than using a TV remote. You can also cast videos to your TV from your phone—just tap the cast icon (it looks like a rectangle with a Wi-Fi symbol in the corner) and select your TV or streaming device from the list. The video will play on your TV while you control it from your phone.
Connecting on a computer or laptop
On any computer, open your web browser (Chrome, Safari, Firefox, or Edge all work) and go to youtube.com. You can watch videos without signing in, but your watch history won't be saved. To sign in, click your profile icon in the top right corner and select "Sign in." Enter your Google account email and password.
Once you're signed in, YouTube will save your watch history, subscriptions, and recommendations. You can also create playlists, like videos, and comment on videos. If you're on a shared computer, sign out when you're done by clicking your profile icon and selecting "Sign out"—this keeps your watch history private from other users.
If you want YouTube on your computer without opening a browser, you can install the YouTube app on Windows 11 or Mac from the Microsoft Store or Mac App Store. The app works the same way as the website but may load slightly faster. On older Windows computers, the YouTube website in your browser is your best option.
Troubleshooting connection problems
If your TV or streaming device can't find YouTube, make sure you're connected to the internet. Check your Wi-Fi network name and password in your device's settings. If YouTube is installed but won't open, try restarting the device by unplugging it for 30 seconds, then plugging it back in. This fixes most app problems.
If the pairing code doesn't work when you enter it at youtube.com/pair, make sure you're using the same Google account on both devices. If you signed in with one account on your TV but you're trying to pair with a different account on your phone, the code won't match. Sign out of the TV app and sign back in with the correct account, then try the pairing code again.
If you see an error message saying YouTube isn't available in your country, you may be using a VPN or proxy that makes YouTube think you're in a different location. Turn off any VPN apps and try again. If you're traveling outside the United States, YouTube may have different content available—this is normal and not a connection problem.
Using YouTube across multiple devices
Once you've signed in with your Google account on any device, that account syncs automatically across all your devices. If you watch a video on your phone, it will show as watched on your TV. If you subscribe to a channel on your computer, that subscription appears on your phone. Your recommendations update based on everything you watch, no matter which device you use.
You can also manage your account settings at myaccount.google.com. From there, you can see all the devices you've signed in on, change your password, turn off watch history, or delete your account entirely. If you want to sign out of YouTube on one device without signing out everywhere, go to that device's YouTube settings and select "Sign out."
Frequently Asked Questions
Do I need a Google account to watch YouTube?
No. You can watch YouTube videos on any device without signing in. However, signing in with a Google account lets YouTube save your watch history, subscriptions, and recommendations. If you don't have a Google account, you can create one for free at accounts.google.com using any email address.
Can I watch YouTube on my old TV that doesn't have apps?
Yes. Plug a streaming device like Roku, Fire Stick, Chromecast, or Apple TV into your TV's HDMI port. These devices cost $25 to $100 and turn any TV into a smart TV. Once connected to your Wi-Fi, you can install YouTube and sign in just like on a newer TV.
What if I forget my Google account password?
Go to accounts.google.com/signin/recovery and enter your email address. Google will send a recovery code to your phone or backup email. Follow the steps to reset your password, then sign back into YouTube on all your devices with the new password.
Can I use YouTube without Wi-Fi?
On a phone or tablet, you can read videos to watch later using the YouTube Premium subscription (paid service). On a TV or computer, you need an internet connection to stream YouTube. Mobile data (4G or 5G) works if you don't have Wi-Fi available.
Why does my YouTube app keep crashing?
Restart your device by unplugging it for 30 seconds or restarting it from the settings menu. If that doesn't work, uninstall the YouTube app and reinstall it from your device's app store. Make sure your device has enough free storage space—apps need room to run properly.
