Yes—usually, if you secure the router and keep the TV maintained. A smart TV is another internet-connected computer on your home network, so its safety depends on Wi‑Fi encryption, strong and unique credentials, current router and TV software, sensible network separation, and privacy settings. No internet-connected device is completely secure, but a short setup checklist substantially reduces avoidable exposure.
What “safe” means for a smart TV
Connecting a television to your network lets it stream video, install apps, receive updates and use services tied to an online account. It also means the TV can communicate with other devices through the router. Security is therefore a system property: a well-protected TV on an outdated router is still exposed, while a current TV on a poorly configured network inherits the router’s weaknesses.

NIST cybersecurity researcher Julie Haney put the risk in practical terms in 2025: “While nothing connected to the internet is completely secure, there are steps you can take to help protect yourself while still enjoying these products.” Treat that as the right standard. The goal is not an absolute guarantee; it is reducing the chance that weak passwords, old software, unnecessary services or excessive data collection create problems.

Weak wireless or router credentials
An attacker who obtains your Wi‑Fi password may reach every device that is allowed on the same network, including the TV. Reusing the router administrator password or leaving the manufacturer’s default credentials in place can also let someone change network settings. WPA3 Personal is the preferred wireless protection when every important device supports it; WPA2 Personal remains the compatibility choice. The Federal Trade Commission describes WPA3 as “the newer — and best — encryption available,” while noting that both WPA3 and WPA2 scramble information.
#1 Best Overall
Unpatched software and apps
Television operating systems and installed apps can contain defects that are fixed through updates. A TV that no longer receives security updates cannot be brought to the same maintenance standard as a supported model. Unused apps add accounts, permissions and code that you do not need, so removing them reduces the number of components that require attention.
Accounts and remote features
Streaming and smart-home services often require an account. A stolen or reused account password can expose viewing history or let another person use the service, even when the home network itself is configured correctly. Remote-management functions, universal plug-and-play, voice controls and microphones can also create capabilities you do not use. Disable them unless a specific feature requires them.
Privacy collection
Smart TVs may collect viewing information for recommendations, advertising or service operation. The exact controls differ by model, region and software version. The FTC’s consumer guidance is direct: “Are you worried about your smart TV watching you? Find your TV’s tracking settings and change them to match your privacy preferences.” Privacy controls reduce data collection, but they do not replace network security.

Secure the router before connecting the TV
Make these changes in the router’s administration interface. Menu labels differ, but the security options are common across current consumer routers.
- Replace default administrator credentials. Change the router administrator username and password if the interface permits it. Use a long, unique password that is not used for Wi‑Fi, email or any other service.
- Set a unique Wi‑Fi password. Choose a password that household members can use without reusing a password from another account. Store it in a password manager if that is practical.
- Choose WPA3 Personal. Select WPA3 Personal when the router and your devices support it. If compatibility problems prevent older equipment from connecting, use WPA2 Personal rather than an obsolete encryption mode. Do not leave the network on an open or legacy setting merely to accommodate one device; place that device on a separate network or replace it.
- Install router firmware updates. Check for updates in the router’s administration page and enable automatic updates where offered. Firmware updates can correct security defects in the equipment that controls every connected device.
- Enable the router firewall. The firewall should remain on for normal home use. It helps control unsolicited traffic between the internet and your internal network, but it does not make weak passwords or unpatched devices safe.
- Disable remote administration. Turn off administration from the internet unless you have a specific, understood reason to use it. If remote management is necessary, restrict it as tightly as the router allows and protect it with a unique credential.
- Turn off WPS and UPnP unless needed. WPS can simplify setup but adds another mechanism to secure. UPnP allows devices to request network mappings automatically. Disable either feature when your household does not depend on it; re-enable it only for a defined compatibility need.
Use a guest or IoT network for separation
If the router supports a guest or IoT network, connect the TV there instead of placing it alongside computers, work devices and personal storage. Segmentation limits what the TV can reach if its software or an app is compromised. It also makes it easier to apply a separate Wi‑Fi password and to change that password without reconnecting every household computer.
Check the router’s isolation setting. A guest network designed only for visitors may block access to printers, casting devices or local media servers. If you need those functions, use an IoT network that provides the required local access while still separating smart-home devices from sensitive equipment. Test streaming, casting and remote-control features after moving the TV; a blocked local connection is a configuration issue, not evidence that the TV is defective.
Harden the TV itself
Update the operating system and apps
Open the TV’s system-update screen, install every available update and enable automatic updates when the option is present. Then open the app store or app-management screen and update installed apps. Restart the TV if the update process requests it. Automatic updating is useful, but check manually after initial setup because some models require a first update before automatic checks begin.
Remove what you do not use
Uninstall unused streaming apps, games and companion services. Sign out of accounts that are no longer needed and remove old profiles. Fewer apps mean fewer permissions and fewer credentials to protect. Do not install software from unofficial sources or bypass the TV’s normal app controls.
Review privacy and permissions
In the TV’s privacy, advertising, voice and app-permission menus, review settings for viewing-information collection, personalized advertising, voice recognition, microphone access and diagnostics. Disable microphone or voice features when you do not use them. A television with a physical microphone switch or camera shutter should be left in the privacy position when those functions are unnecessary. Menu names and available controls vary by model, region and software version, so use the model-specific support documentation.
Rank #4
Protect the associated account
Use a unique password for the manufacturer or streaming account and enable multi-factor authentication when offered. Do not share the account password with installers or guests. Review the account’s signed-in-device list periodically and remove devices you no longer own.
Wi‑Fi versus Ethernet
Ethernet can be a sensible alternative when the TV is near the router or a network outlet, but it is not a complete security solution. Both connection types still use the same router, TV software, account protections and privacy controls.

Choose Ethernet for reliable connectivity or convenience, not because it makes hacking impossible. If you use a cable, keep the router firewall enabled and apply the same segmentation and update policy.

Find the manufacturer’s security-update policy for the exact model and region. A TV can still display video after support ends, but an unsupported device cannot receive fixes for newly discovered defects. Retire it, keep it disconnected from the network, or replace it when the remaining risk is unacceptable.
One published example illustrates why policies must be checked rather than generalized. Samsung’s 2026 security policy says smart TV and monitor products launched from January 2023 will receive security updates for seven years from their initial launch. The same policy guarantees five years of software-update support for other smart TVs covered by that policy. These periods apply to the products and conditions Samsung specifies; they are not a promise for every manufacturer or model.
Roku documents that supported TVs and players check for updates during setup and periodically, install updates automatically, and allow a manual update check. Samsung documents both Wi‑Fi and Ethernet setup and says a Samsung Account is required for network-based smart services such as streaming apps. LG documents LAN-cable and wireless-access-point setup for webOS TVs. Exact menu names, update behavior and account requirements vary by model, region and software version.
A safe setup sequence
- Inventory the equipment. Record the TV model, operating-system version, router model and the date you first connect the TV.
- Secure the router. Change administrator and Wi‑Fi credentials, select WPA3 Personal or WPA2 Personal, update firmware, enable the firewall, and disable remote management, WPS and UPnP unless required.
- Create separation. Set up a guest or IoT network and confirm whether it supports the casting, media-server or remote-control features you need.
- Connect the TV. Use the separated wireless network or a wired Ethernet connection. Enter the new Wi‑Fi password only on the TV’s normal network screen.
- Update immediately. Install TV firmware and app updates before signing in to services. Turn on automatic updates where available.
- Minimize features. Remove unused apps, disable unused microphones, voice controls, remote management and tracking options, and review app permissions.
- Secure accounts. Use unique passwords and multi-factor authentication where supported. Check signed-in devices after setup.
- Schedule maintenance. Check for updates periodically and revisit the manufacturer’s support page before the published support window ends.
Symptoms that deserve attention
- The TV repeatedly asks for a network password after you changed it: remove the saved network from the TV, restart both devices, and reconnect using the new credentials.
- Streaming works but casting or a phone remote no longer does: verify that the phone and TV are allowed to communicate on the guest or IoT network, or use the router’s approved local-access setting.
- The TV cannot find an update: confirm internet access, check the model-specific support page, and try the manual update option documented for that model.
- An account shows an unfamiliar device or viewing activity: change the account password, enable multi-factor authentication, sign out other sessions and review installed TV apps.
- The TV is outside its security-support window: disconnect it from the network rather than treating continued video playback as evidence that it remains secure.
When should you avoid connecting the TV?
Keep the TV offline when it no longer receives security updates, when you cannot change the router’s default credentials, or when a required app will only work with unsafe legacy network settings. You can still use a separate, offline source such as a media player or antenna, provided that the replacement device is itself maintained. If the TV must be online temporarily, place it on the most isolated network available, remove unnecessary apps and accounts, and do not use it for sensitive services.
The practical verdict
A smart TV is generally reasonable to connect when the router uses WPA3 Personal or WPA2 Personal, has unique credentials, current firmware, an enabled firewall and (where practical) a guest or IoT network. Keep the TV and apps updated, remove software you do not use, limit microphones and tracking, protect associated accounts and verify the manufacturer’s support window. Ethernet can improve connection stability and remove the TV’s wireless link, but it does not remove the need for those controls. Security is strongest when the network and the TV are maintained together.
