How to block Xiaomi through Mi Account: a guide

Losing a smartphone or stealing it is a stressful situation that requires immediate action. Xiaomi’s current devices, powered by MIUI or HyperOS, feature a powerful security tool called Find Device, which not only tracks the location of the gadget, but also completely blocks access to it, turning the device into a useless piece of plastic for an attacker.

Remote locking is done through a Mi Account and requires that the device be enabled with a search function. In this article, we will discuss the process of activating protection, consider the nuances of the operation of the missing mode and answer questions about what to do if the phone is offline. Understanding these mechanisms is critical to preserving your personal information.

The principle of remote locking through the cloud

The backbone of security is the Xiaomi Cloud cloud service. When you type a lock command through a web interface, the signal is sent to the company's servers, which in turn try to communicate with your device. If the smartphone is connected to the Internet (via a mobile network or Wi-Fi), the lock is almost instantaneous.

However, there are situations where communication with the server is impossible, in which case the command is put in line and will be executed as soon as the gadget appears on the network, it is important to understand that locking mode is different from simply turning off the screen: it requires entering the unlock password or Mi Account data to access the system.

⚠️ Warning: If the attacker immediately SIM-The card and the Wi-Fi shutdown will not be immediately accessible by the command, but once the phone is connected to any network, the lock is forced to activate.

To work efficiently, the phone needs to activate geolocation services and data transfer, without which remote control loses its functionality, leaving the owner without leverage.

Preparing the device for possible locking

For remote control to work properly, you have to make a number of adjustments in advance, and many users ignore this step, relying on standard settings, which can be a cruel joke at a critical moment, and it takes only a few minutes to check these settings, but ensures the security of your data.

First of all, make sure that the device is signed in to Mi Account, which is the key to managing your smartphone. Without authorization, cloud services will not work, and you will not be able to use search or lock functions.

Then you activate the search function itself, and then go to the security settings and find the appropriate item, and the path may vary slightly from firmware to firmware, but the logic remains the same.

• 🔑 Go to Settings. → Mi Account and check the login status.
• 📍 Open the Security section and find the Find Device.
• 📡 Make sure that the “Enable Find Device” and “Last Location” sliders are active.

You should also pay attention to location permission, and the system can ask permission to determine the coordinates "Always" or "Only in use." For standby search, you should choose the "Always" option, so that the phone transmits the coordinates even in sleep mode.

Step-by-step instruction to block through a web-based interface

If you've had a problem, you need to act quickly and in a cool way, and you need any other gadget with Internet access, like a computer, a tablet, or a friend's phone, and the main tool is the official cloud site.

Open your browser and go to cloud.mi.com or i.mi.com. Enter your login credentials (login and password) that were used on the lost device. Once you have successfully logged in, you will see the main menu of the cloud.

Click on the Find Device icon. The system will try to locate your gadgets associated with this account, select the device you want from the list (if there are more) and wait for the map to appear.

To block, click Lost Mode, you will be asked to enter the phone number that will be displayed on the lock screen and a text message, which will help the honest finder to contact you.

⚠️ Warning: Once you activate the loss mode, the phone will be locked with a password. You can change it or unlock the device only if you know the password from the Mi Account.

If the device is offline, the system will prompt you to activate the lock when you first appear on the network. Don't ignore this option, it guarantees protection even if the phone is turned on in a few days.

Functionality of the “Disappearance regime”

Activating this mode triggers a series of processes aimed at saving data and limiting the functionality of the smartphone, the screen goes out, and the message you typed with the contact number appears on it, and attempts to unlock the phone with a standard pattern lock or fingerprint will not succeed.

Importantly, this mode disables NFC for payments, which prevents unauthorized purchases in stores, even if the phone is somehow unlocked (which is almost impossible without an account password).

The camera can also be used by security, and some firmware versions allow you to take a hidden photo of someone trying to unlock the phone and send it to you by mail or save it to the cloud.

• 🔒 Access to settings and menus is blocked.
• 📵 Calls are disabled (except for emergency numbers).
• 📸 An attempt to take hidden photos when unblocking is unsuccessful.

Using a missing mode is the most civilized way to get a device back, and often people who find a phone, when they see a number message, prefer to contact the owner to get a reward, rather than carrying the device to buy.

Remote data cleaning as a last resort

If you realize that the phone is stolen by professionals and there will be no return, or if the device holds critical trade secrets, the last option is a complete cleanup, which permanently deletes all user data.

To activate, press the Wipe Data button in the cloud interface, the system will request confirmation, warning of irreversibility of action, and then the phone will be reset to a factory state.

However, even after the reset, the device will remain tied to your account thanks to Anti-theft protection, which will only be re-enabled after the username and password of the owner are entered, which makes the theft of such a phone pointless for resale.

⚠️ Note: After remote cleaning, you will lose the ability to track the location of the phone. Coordinates will stop updating, as the connection with the account will be severed before activation.

Use this feature only if there is no hope of return. Remember that local copies of data (photos, contacts) will be destroyed if they were not synced with the cloud in advance.

💡

Check your contacts and photos with Mi Cloud regularly, and if you lose your phone, you can recover all the information on your new device immediately after you sign in.

Frequent problems and ways to solve them

Users often encounter technical difficulties when trying to lock a device, and the most common problem is that the phone does not respond to commands, which may be due to an unstable Internet connection or power saving settings.

Sometimes the system writes an authorization error, in which case make sure that you enter the password from the Mi Account, not from the Google account or the screen unlock password. These are different accounts, and you can not confuse them.

If the phone was reset to factory settings by an attacker, but the search function was enabled, it still requires a password to be entered at the first activation, and if the search function was pre-disabled, then nothing can be done remotely with the device.

In some cases, re-authorizing on the site helps, try logging out and logging in again to update the status of your devices, and check if the antivirus or firewall has blocked access to the cloud site.

💡

The effectiveness of the lock depends on whether the Find Device feature was enabled before the phone was lost, and it is the responsibility of each Xiaomi owner to check in advance.
