Losing or stealing a smartphone is stressful, especially if the device stores personal photos, access to banking applications or corporate correspondence. Xiaomi offers several official ways to remotely lock the phone, but their effectiveness depends on preliminary settings. In this article, we will analyze all the current methods of blocking a lost Xiaomi smartphone, including little-known nuances that will help protect data even without prior preparation.
It's important to understand that the speed of reaction is critical. The faster you lock a device, the lower the risk of information leakage or unauthorized purchases through tied cards. We analyzed Xiaomi's official instructions, user reviews and recommendations from cybersecurity experts to compile the most complete guide. In this article, you will find not only standard ways through Mi Account or Find My Device, but also alternative solutions for cases where basic methods are not available.
1.Blocking through Mi Account is the main method
The most reliable and quickest method is to use the official Mi Cloud service (part of the Xiaomi ecosystem), which works on all models from Mi 5 (2016) to newer, provided that the device has enabled Mi Account and data synchronization. SIM-card removed or phone turned off (on next Internet connection).
To lock the phone:
- Go to account.xiaomi.com and log in with the same account that was linked to the lost device.
- In the Devices section, select the lost smartphone from the list (if it is not, check if it is hidden in the archive).
- Click Find the device, then select the option to Lock.
- Set a new lock password (at least 6 characters, with numbers and letters) and confirm the action.
Important nuances:
- 🔄 If the phone was reset to factory settings before locking, Mi Account won’t work – an attacker can activate the device as a new one.
- 📡 The lock is only applied when connected to the Internet (Wi-Fi or mobile network). If the phone is offline, the command will be executed when you first log in.
- 🔒 After blocking through Mi Cloud, you can only unlock the device by entering the password of your Xiaomi account.

💡
If you do not remember whether Mi Account is linked to your phone, check your login history in your account.xiaomi.com profile under the Security section.
2 Use Google Find My Device
If Google’s Find My Device service was enabled on the lost Xiaomi (which is activated by default when you add a Google account), you can lock the phone through a web interface or other Android device, which works independently of the Mi Account and is suitable for cases where the main Xiaomi account was not tied.
Instructions:
- Go to the site. google.com/android/find Log in to the same Google account that was used on your phone.
- At the top of the screen, select the lost device from the list (if there are several).
- Click Lock the device and follow the system prompts.
- Set a new password to unlock and, if necessary, provide a contact number for communication.
Find My Device not only locks the phone, but also removes all data from it remotely – useful if the device stores critical data (such as cryptocurrency wallet access or corporate information), but once reset, it will be impossible to track the phone.

Blocking through the operator (by IMEI)
If the phone is stolen, not just lost, it makes sense to lock it down. IMEI — This method will not allow an attacker to use the phone in the networks of Russian operators (MTS, Beeline, MegaFon, Tele2), but has limitations:
- 📵 The blocking is valid only in Russia (abroad). SIM-cards can work).
- 🔧 Not all operators provide this service for free (for example, MTS blocks the service). IMEI Free, and Beeline can charge a fee).
- 🕒 The process takes from several hours to 3 working days.
To lock the phone over IMEI:
- Find it. IMEI Lost device (if not saved before, check the box from the phone or check purchase).

- Write a request for blocking on IMEI. The operator will transfer the data to the common database.
⚠️ Attention: Blocking by IMEI It does not protect the data on the phone, it only makes it useless for an attacker as a means of communication. If the device was enabled cloud backups (Mi Cloud or Google Drive), we recommend further erase the data remotely via Mi Account or Find My Device.
4. Alternative methods: what to do if the basic methods do not work

- 🏦 SberBank Online: Go to security settings and delete the current session.
- 💳 In Tinkoff: in the web version of the bank, find the Devices section and revoke access for the lost phone.
4.2. data deletion via Samsung Find My Mobile (if the phone supports Knox)
Some Xiaomi models (e.g. Mi Mix) 2S POCO F1) If your phone is one of those devices, try logging in to findmymobile.samsung.com — sometimes it works even on the offline.-Samsung devices with Knox installed.
4.3. Contacting the police
If the phone is stolen, we recommend you report it to the police.
