How to disable the password on Xiaomi Mi Band 4: all ways to unlock

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular gadgets for tracking activity, despite the release of new models, its main advantage is reliable data protection, including the ability to set a 4-digit password to unlock the screen. However, many users face the problem: forgotten code blocks access to the functions of the bracelet, and official documentation Xiaomi does not always offer clear solutions.

In this article, we will discuss all the current ways to disable the password on the Mi Band 4, including resetting through the Mi Fit application, hardware reboot and alternative methods for cases where standard instructions do not work. Special attention will be paid to preserving data on training and heart rate - this is critical for those who keep health statistics. If you tried to enter the code more than 5 times and the bracelet is blocked, here you will find a solution.

Why Mi Band 4 asks for a password and how it works

Password protection on the Mi Band 4 is activated manually through the bracelet menu or automatically after several failed unlock attempts.

• 🔒 Password consists of 4 digits (from 0000 to 9999).
• 📱 Installation or through the bracelet (Settings) → Password, or in the Mi Fit app (older versions).
• ⏳ After 5 wrong attempts, the bracelet is blocked for 30 seconds, then the time increases.
• 🔄 Resetting a password through the application is possible, but requires binding the bracelet to the Xiaomi account.

It’s important to understand that the password on the Mi Band 4 is local protection, not cloud protection, which means that even if you reset the bracelet settings through the Mi Fit, the training data for the past 30 days can be stored in the device’s memory (if you didn’t perform a full reset), however, when hardware reset, all information is erased irrevocably.

If you don't remember the password, but the bracelet is synced to the phone, the chances of unlocking without losing data are higher, otherwise you'll have to use hardware techniques, which we'll talk about later.

Method 1: Reset password through the Mi Fit application (official method)

This is the safest way, but it only works if:

• 📱 The bracelet is tied to your Xiaomi account in Mi Fit.
• 🔗 The device has synced with the phone at least once in the last 7 days.
• 📶 The phone has Bluetooth and internet on.

Step-by-step:

1. Open the Mi Fit app on your phone.
2. Go to the Profile section → Mi Smart Band 4.
3. Tap it on three points (⋮) in the upper right corner and select Untie the device.

⚠️ Warning: If the bracelet does not reset after detachment, try restarting it manually (press the touch button for 10 seconds.

This method stores data in the Xiaomi cloud, but local recordings on the wristband (steps, pulses over the last day) may disappear. If the synchronization has not worked for a long time, the information will not be able to recover.

Method 2: Hard Reset – If you forget your password

If the bracelet is not synced to your phone or you don't remember your Xiaomi account details, you only have to reset completely, and this method erases all data from the device, including:

2. Find the touch button (under the screen) on the back of the Mi Band 4.
3. Hold it for 15-20 seconds until the Mi logo appears on the screen.
4. Release the button. The bracelet vibrates and starts the reset process.
5. After rebooting (about 1 minute), the device will be as new as the new one.

⚠️ Warning: After hardware reset, the bracelet may require a firmware update.If you have an older version of the Mi Fit (up to 4.6.0), update the app first, otherwise the Mi Band 4 won't connect.

Method 3: Unlocking through third-party apps (for power users)

If the official methods didn’t work, you can try specialized utilities like Mi Band Master or Notify & Fitness.

• 🔓 Reset password without decoupling from account.
• 📥 Save data before resetting.
• 🛠️ Restore settings from backup.

Instructions for Mi Band Master:

1. Download the app from Google Play.
2. Connect the bracelet via Bluetooth (select Mi Band 4 in the app).
3. Go to the Tools section → Unlock.
4. Follow the instructions on the screen (it may be necessary to enter code from the bracelet).
5. Once unlocked, sync the data to the cloud.

Before using third-party apps, disable Mi Fit in your phone's Bluetooth settings. Connection conflict can lead to synchronization errors.

⚠️ Note: Some apps require root rights on the phone or install additional drivers.This may violate the Xiaomi warranty and lead to unstable bracelet performance.

What to do if the bracelet is blocked after unsuccessful attempts to enter a password

If you have made a mistake several times when you enter the code, Mi Band 4 can lock for 30 seconds, 5 minutes or even forever (depending on the firmware version).

• ⏳ Temporary lock (up to 5 minutes): Just wait the specified time. the bracelet unlocks automatically.
• 🔄 Permanent lock: Requires a reset via Mi Fit or Hard Reset.
• 📵 Bracelet unresponsive: Connect it to charging for 10 minutes, then try resetting with a button.

In firmware 1.0.9.54 and later after 10 failed attempts, the bracelet requires a mandatory reboot. If you see a lock icon and the words LOCKED on the screen, use the Hard Reset method 2 from this article.

💡

If the bracelet is locked after updating the firmware, first try rolling it back through Mi Fit. In some cases, this removes the lock without losing data.

• 📲 Mi Fit version of the app (update to the latest).
• 🔋 Bracelet charge level (below 10% may cause failures).

3. Synchronize the data regularly, and this will help you to recover the statistics even after the reset.
4. Update the firmware. The new versions fix the lock bugs.

If you still decide to leave a password, set up automatic unlock when connecting to the phone:

2. Activate the Unlock option when connecting.
