Smart TV owners often think about the security of their device, especially if there are young children in the house or different people use the TV. Set a password on a Xiaomi TV is not just a way to restrict access to content, but also a necessary measure to protect personal data and purchases in the app store. Unlike smartphones, where screen locking has become a standard, on large screens this feature is implemented with some features that depend on the version of the operating system.
The challenge is that there is no single “password to the entire TV” button in pure Android TV, but the Xiaomi ecosystem and PatchWall offer flexible tools to do this: You can secure login, restrict the launch of specific apps, or activate strict parental controls, and understanding these mechanisms will allow you to create a robust barrier to outsiders.
In this article, we will take a look at all the security options available, from standard security settings to guest profiles, and look at the nuances of remote control, voice control, and the limitations you may face in the setup process. Get ready to turn your Smart TV into a secure multimedia device.
Basic protection of Google account and system
The first layer of defense is to protect the account through which the TV operates. Because Android TV is deeply integrated with Google services, setting a password to log in to a profile often automatically requires authorization to access synchronized data. To activate this feature, you need to go to the settings menu and find the section responsible for device security.
It’s important to understand that simply locking your screen, like on your phone, works differently here. The system may request confirmation when you try to change your system settings or make a purchase on Google Play. To activate protection, go to Settings → Device → Security and activate the check option when you purchase or install apps.
⚠️ Note: If you forget your Google account password, restoring access to your purchased movies and TV subscriptions can take a considerable amount of time and require access to your linked phone.
You can also set up two-factor authentication for your Google account, which doesn’t require you to enter a code every time you turn on your TV, but prevents you from logging in from other devices if someone tries to do so using the stored data.
💡
Use complex passwords for your Google account, as credit card details are often stored through the TV to pay for subscriptions.
Use of Parental Controls by PatchWall
PatchWall, which is the standard for Xiaomi and Redmi TVs, has a powerful built-in tool to restrict access. Parental controls allow you to hide certain content or require a pin code to view it. This is the most effective way to "set a password" on specific sections of the interface.
To set up, go to the child's profile or activate the restriction mode in the main interface settings. You will be prompted to create a four-digit PIN-The code you need to exit child mode or run blocked apps is ideal for situations where you need to restrict children's access to adult movies or paid channels.
The system allows you to flexibly adjust filters, you can choose the age rating of content that will be available without a password, and everything higher will be hidden or blocked, and you can also limit the time you use your TV, which is a unique feature of the Mi Home ecosystem.
- 🔒 Installation PIN-code to exit the child profile.
- 📺 Blocking the launch of applications with high age rating.
- ⏱️ Limiting viewing time during the day.
- 🚫 Hiding certain categories of content in the recommendation feed.
Blocking specific applications
If you don’t need to block the entire interface, but only access to certain programs (such as YouTube, Netflix or the browser), you can use the application blocking feature. In some versions of MIUI for TV firmware, this option is built-in, in others you will need to install third-party but proven software.
Native lock is in Settings → Applications → Application Lock. Here you select a list of programs that will only be accessible after you enter a password. When you try to open such an application, a code request will appear on the screen.
If there is no built-in feature, it is recommended to use specialized launchers or utilities from Google Play, such as "App Lock", which work on top of the system and intercept the launch of selected programs, requiring authorization, which creates the effect of a full password on the application.
⚠️ Note: When installing third-party blockers, make sure they are optimized to control from the remote, otherwise you may encounter the inability to enter a password without connecting the keyboard.
☑️ Setting up an application blocker
Guest mode and user profiles
Android TV supports multiple user profiles, similar to guest mode, which is a great way to share access: the main profile with passwords and purchases remains secure, and the guest profile has limited functionality.
To create a guest profile, go to account settings and select Add User. The guest won't need your password, but won't be able to see your apps, browsing history, or make purchases. Switching between profiles requires confirmation from the administrator (main profile owner).
This method does not put a password on your TV, but effectively isolates your data, the guest sees only a basic set of applications and does not have access to system settings or the file system.
| Profile type | Access to applications | Purchases | Viewing history |
|---|---|---|---|
| Owner | Complete. | Permitted. | Seen. |
| Child. | Limited to filters | Locked down. | Hidden. |
| Guest. | Basic set | Locked down. | It doesn't last. |
Can I remove the guest profile?
Restricting purchases on Google Play
One of the most critical security issues is protection against accidental or unauthorized purchases: children can accidentally buy a subscription or movie unless additional security is installed. The Google Play store settings on the TV have a separate authentication section.
Go to Settings → Custom Settings → Require authentication for purchases. Here you can select “For all purchases through Google Play on this device” option, after which any payment will require you to enter a password from your Google account.
It is also recommended to remove the associated means of payment from the child or guest profile, if any, even with a password, it is better to minimize the risks, leaving the possibility of payment only on the main, secure profile of the owner.

- 💳 Disabling autopayment in children's profiles.
- 📧 Notifications by email about purchases made.
- 🚫 Blocking the installation of applications with internal purchases.
💡
The most reliable protection of finance is a combination PIN-purchase code and no linked card in profiles available to children.
Third-party solutions and timer lock
For advanced users who lack standard tools, there are timer or schedule-based locking apps, such as TV App Repo or specialty launchers, that can completely block the TV interface after a certain time or on command.
Some smart outlets in conjunction with Mi Home can simulate locking by turning off power, but this is not a software password and is not recommended for frequent use, as it can damage the file system if you do not finish work correctly.
The use of third-party launchers allows you to replace the standard shell with a more secure one, where login is possible only on the basis of the standard shell. PIN-However, installing such launchers requires downloading. APK-files via a flash drive, as in the official store they may not be.
⚠️ Attention: Installation of untested APK-Files from unknown sources can cause viruses to infect the TV.
