Authorization in Xiaomi: from registration Mi Account to unlock the bootloader

Xiaomi’s ecosystem requires authorization at almost every stage of interaction with the brand’s technology, from the first turn on the smartphone to synchronizing smart devices in the Mi Home. Without a properly configured Mi Account, you will not be able to use cloud storage, unlock a custom firmware bootloader or even restore access to the device after a reset. In this article, we will analyze all the ways of authorization in Xiaomi services, including solutions to typical problems and nuances for different regions.

The key to Xiaomi’s authentication is that it’s multi-level: a simple account registration can solve some tasks (e.g., accessing Mi Cloud), but unlocking the bootloader or using some of the smart home features will require additional steps. We’ll look at each scenario, from basic to advanced, and explain why authorization via a phone number from China can block an account for users from other countries and how to avoid this.

1. Mi Account Registration: The First Step into Xiaomi’s Ecosystem

Without Mi Account, you can’t activate Xiaomi smartphone, sync data between devices or use branded services. Registration takes no more than 5 minutes, but there are nuances that affect the further use of the account.

You can create an account in three ways:

• 📱 Through the Mi Account mobile app (available on Google Play and App Store)
• 🌐 On account.xiaomi.com
• 📦 When you first turn on a Xiaomi smartphone or tablet (the system will offer to register)

It is important to choose the right account region – this depends on the availability of services. For example, an account registered in China (cn) will not be able to use Google Play on global firmware, and an account from Russia (ru) may face restrictions when buying devices on AliExpress.

If you plan to use Xiaomi outside of China, choose a Global region or your current one (e.g. Russia, India, Europe). You can’t change the region after you register.

2.Authorization on a smartphone: entry, recovery and reset

Once you register for a Mi Account, you need to link it to your device, and on Xiaomi smartphones, this happens automatically when you first log in, but there are cases when you need to log in again:

• 🔄 After resetting (Hard Reset)
• 🔐 When unlocking the screen through Find Device
• 📱 After updating MIUI with changing firmware region

To log in on your smartphone:

1. Go to Settings → Xiaomi account.
2. Enter the email or phone number associated with the account.
3. Confirm your login via SMS or email (depending on your security settings).

If your smartphone requests authorization after a reset but you don’t remember your account details, use the recovery function at account.xiaomi.com. This will require access to the email or phone specified during registration. If access is lost, the only way to unlock it is to contact Xiaomi with a confirmation of purchase (check or warranty card).

⚠️ Warning: When buying a used Xiaomi smartphone, always check to see if the previous Mi Account is untied. If the device is tied to someone else's account, you will not be able to use cloud services and may face lockdown after a reset.

3. Authorization for unlocking the bootloader (Bootloader Unlock)

If you plan to install custom firmware (for example, LineageOS or Pixel Experience), you will need to unlock the bootloader.

The process consists of several stages:

1. Account binding to the device: Mi Account must be added in the smartphone settings and confirmed via SMS/email.
2. Request permission to unlock: In the Mi Unlock Tool, you need to send a request to Xiaomi servers. Usually, the permission comes within 3-7 days (sometimes longer).
3. Direct unlock: Once approved, you can unlock the bootloader through the same utility.

Important conditions for successful unlocking:

• 📱 The device must be on official firmware MIUI (no castom firmware is supported).
• 🔗 The account must be tied to the device for at least 72 hours (a rule introduced to combat theft).
• 🌍 The region of the account must be the same as the firmware region (e.g., global firmware + global account).

If the Mi Unlock Tool is running a "Couldn't unlock" or "This device is locked" error, check:

• Internet connection (the utility requires a stable connection to Xiaomi servers).
• Version of the utility (download the last from the official website).
• Administrator rights on the PC (the utility requires the installation of drivers).

4.Authorization in Mi Home and Xiaomi Smart Home

To control smart Xiaomi devices (Yeelight lamps, Mi Robot robot vacuum cleaners, Aqara sensors) requires authorization in the Mi Home application.

First, the region of the account determines which devices will be available for add-on, for example, if your account is registered in Russia, you will not be able to connect devices designed only for China (and vice versa), and secondly, some devices require additional authorization through Mi Cloud for remote management.

To log in to Mi Home:

1. Download the app from Google Play or App Store (the version should match your account region).
2. Sign in under your Mi Account.
3. Add the device through Profile → Add the device.

If the device is not added, check:

💡

If you are buying a Xiaomi smart device from China, check before buying whether it supports global servers. Some models (such as the Mi Air Purifier 3C) only work with Chinese accounts and require a VPN to set up.

5 Two-factor authentication (2FA) and account security

Xiaomi offers two-factor authentication (2FA) to protect your account from hacking, especially if you use the Mi Cloud to store photos, contacts or backups. Enable 2FA in the Mi Account settings:

Go to Settings → Xiaomi Account → Account Security → Two-step verification. The system will suggest linking a phone number or email for confirmation. Once activated, a code from an SMS or email will be requested each time you log in from the new device.

The benefits of 2FA:

• 🔒 Protection against unauthorized access even if a password is leaked.
• 📱 The ability to track login attempts (a notification arrives at each authorization).
• 🔄 Access recovery via backup codes (they must be saved when configured).

⚠️ Warning: If you lose access to email and phone linked to 2FA, it will be extremely difficult to restore your account. Xiaomi requires proof of identity through a passport scan and a check to purchase the device. Keep your backup codes in a safe place!

If you sell or transfer a Xiaomi device to another person, remember to:

1. Untie Mi Account in Settings → Xiaomi Account → Sign out.
2. Reset the device to factory settings (Settings → Additional → Recovery and Reset).
3. Remove the device from the list in Mi Cloud (via the web version or app).

6. Authorization through third-party services (Google, Facebook, Apple ID)

In addition to standard authorization via email or phone, Xiaomi supports login via third-party accounts: Google, Facebook and Apple ID. This is convenient if you do not want to remember another password, but there are risks:

First, linking to a third-party service means that access to Mi Account depends on the security of that service. For example, if your Google account is hacked, an attacker will gain access to Xiaomi. Second, some features (for example, unlocking the bootloader) may not be available when logged in through third-party services.

To log in via Google or Facebook:

1. On the Mi Account login screen, select the appropriate icon.
2. Confirm access to the data (the system will redirect you to the authorization page of the selected service).
3. Allow Xiaomi to use your data (email, name).

If you decide to unplug a third-party account, do so in the Mi Account settings:

• Go to Settings → Xiaomi Account → Account Management.
• Choose a linked service (Google, Facebook, etc.).
• Press Untie and confirm the action.

💡

Authorization through third-party services is convenient, but not suitable for unlocking the bootloader or restoring access to a locked device. In such cases, you will need a standard Mi Account with a email/ phone.

7. Solving authorization problems: errors and blockages

Even with the right actions, users are faced with authorization errors.

Error: "This account is not available in your region"

Reason: The region of the account does not match the region of the device or firmware, such as the Chinese account (cn) on global firmware.

Solution: Create a new account in the right region or change the firmware region (via Fastboot or Mi Flash Tool).

Error: "Device is locked by Mi Account"

Reason: The device is tied to another account (often found when buying used phones).

Solution: Contact the previous owner and ask to untie the device, and if that is not possible, contact Xiaomi with proof of purchase.

Error: "Network error. Please try again"

Reason: Problems connecting to Xiaomi servers (often due to VPN or ISP blocking).

Solution: Disable VPN, check your internet connection, or try logging in via mobile.

If your account is blocked due to suspected fraud (for example, due to frequent IP change or attempts to unlock the bootloader), you can restore it through the feedback form on account.xiaomi.com.

• 📄 Scan of passport or other identity card.
• 📋 Check or warranty card on a Xiaomi device.
• 📧 Access to the email specified during registration.
