The fastest way to block YouTube on Vizio

Vizio TVs let you block YouTube through the parental controls menu, which prevents anyone from opening the app without entering a PIN code. The steps differ slightly depending on whether your TV runs Vizio's older SmartCast system or the newer Vizio SmartTV platform, but both take about five minutes to set up.

On newer Vizio SmartTV models, go to Settings > Parental Controls > App Lock, then select YouTube from the list of apps and toggle it on. You'll create a four-digit PIN that anyone trying to open YouTube will need to enter. On older SmartCast TVs, the path is Settings > Parental Controls > Blocked Apps, where you select YouTube and confirm the block.

Once YouTube is blocked, the app won't appear on your home screen and won't launch if someone tries to open it from the app list. The block stays in place until you return to the same menu and disable it using your PIN.

Key Takeaways

  • Vizio's parental controls let you block YouTube by PIN-protecting it so the app won't open without a code you set.
  • Newer Vizio SmartTV models use Settings > Parental Controls > App Lock, while older SmartCast TVs use Settings > Parental Controls > Blocked Apps.
  • You create a four-digit PIN when you first block the app, and you'll need that same PIN to unblock it later.
  • Blocking YouTube through parental controls is different from signing out of your Google account, which only removes your personal data but leaves the app usable.

Blocking YouTube on Vizio SmartTV (newer models)

If your Vizio TV was made in 2021 or later, it likely runs the Vizio SmartTV platform. To block YouTube, pick up your Vizio remote and press the V button (or the home button) to open the main menu. Navigate to Settings using the arrow buttons.

Once in Settings, scroll down to find Parental Controls and select it. You may be asked to enter a PIN if you've already set one up; if not, you'll create one now. After entering Parental Controls, look for App Lock and select it. A list of apps will appear—find YouTube in that list and toggle it on. The TV will prompt you to confirm a four-digit PIN. Write this PIN down somewhere safe; you'll need it to unblock YouTube later.

After you confirm, YouTube will be blocked. The app won't appear on your home screen, and if anyone tries to find it in the full app list, they'll see a lock icon next to it. Attempting to open it will bring up a PIN entry screen.

Blocking YouTube on Vizio SmartCast (older models)

Vizio TVs from 2020 and earlier use the SmartCast system. To block YouTube on these models, press the Menu button on your remote. Navigate to Settings and then Parental Controls.

In the Parental Controls menu, select Blocked Apps. You'll see a list of available apps; find YouTube and select it to block it. The TV may ask you to set a PIN at this point if you haven't already. Once you confirm, YouTube will be blocked and won't open when selected.

The main difference between SmartCast and SmartTV blocking is that SmartCast removes the app from view entirely, while SmartTV shows it with a lock icon. Both methods prevent the app from running without the PIN.

Setting and remembering your parental control PIN

When you first block an app, Vizio asks you to create a four-digit PIN. This PIN is separate from your TV's main PIN (if you have one) and is used only for parental controls. Choose a code that's not obvious—avoid 1111, 0000, or your birth year.

Write the PIN down and store it somewhere you'll remember but a child won't find, like a note in a drawer or a password manager. If you forget the PIN, you'll need to perform a factory reset on your TV, which erases all settings and apps. There's no way to recover a lost parental control PIN without resetting the entire TV.

If you want to change the PIN later, go back to Parental Controls, select the option to change your PIN (the exact menu item varies by model), and enter your current PIN before creating a new one.

The difference between blocking and signing out

Blocking YouTube through parental controls is not the same as signing out of your Google account on the TV. When you sign out, you remove your personal data—your watch history, subscriptions, and recommendations—but the YouTube app itself remains usable by anyone. A child could still open YouTube and watch content; they just wouldn't see your account.

If you want to prevent YouTube from being used at all, blocking through parental controls is the right choice. If you only want to remove your personal information from the TV, signing out of your Google account is faster but doesn't restrict access to the app.

Unblocking YouTube when you need to

To unblock YouTube, return to the same menu where you blocked it. On SmartTV, go to Settings > Parental Controls > App Lock, find YouTube, and toggle it off. On SmartCast, go to Settings > Parental Controls > Blocked Apps and deselect YouTube. Either way, the TV will ask you to enter your four-digit PIN to confirm the change.

Once you unblock it, YouTube will reappear on your home screen and in the app list, and anyone can open it without a PIN. The app itself isn't deleted—it's just no longer restricted.

What to do if you can't find Parental Controls

If you can't locate Parental Controls in your Settings menu, your TV may be running a version of the software that doesn't support app-level blocking, or the menu structure may be different than described here. Check your TV's model number (usually on the back or in Settings > About TV) and search the Vizio support website for your specific model's manual.

Vizio's support site has downloadable PDFs for each TV model that show the exact menu paths for your hardware. If your TV is very old or runs an unusual software version, app blocking may not be available, but you can still sign out of your Google account to remove personal data from the YouTube app.

Frequently Asked Questions

Can I block YouTube but allow other apps?

Yes. Parental Controls lets you block individual apps one at a time. You can block YouTube while leaving Netflix, Disney+, or any other app unblocked. Each blocked app uses the same PIN code you set up in Parental Controls.

What happens if someone enters the wrong PIN?

The TV will show an error message and won't open the app. There's no penalty for wrong guesses—the person can try again when ready. Vizio doesn't lock the app after multiple failed attempts, so the PIN is only as strong as its secrecy.

Does blocking YouTube on the TV block it on other devices?

No. Blocking YouTube on your Vizio TV only affects that TV. If you have a phone, tablet, or computer connected to the same WiFi, YouTube will still work on those devices. Parental controls are local to the TV itself.

Can I block YouTube on a Vizio TV I don't own?

You can set up the block if you have access to the TV's remote and Settings menu, but you'll need the TV owner's permission. If the TV already has a parental control PIN set, you'll need that PIN to make changes. Blocking an app on someone else's TV without permission isn't recommended.

What if I reset my TV—will YouTube still be blocked?

A factory reset erases all settings, including parental controls. After a reset, YouTube will be unblocked and usable again. This is why keeping your PIN written down is important—if you forget it, a factory reset is the only way to regain access to the TV's full settings.
