Ever wondered where Xiaomi stores your Wi-Fi passwords, apps, and accounts? Unlike iPhones or Samsung, where the password manager is often integrated into cloud services (iCloud Keychain or Samsung Pass), MIUI devices use a combined system, which includes both local storage in protected memory areas and synchronization through Mi Account. The problem is that users rarely know where that data is physically located β which is critical if you need to back up before reset or restore access after a breakdown.
In this article, we will not only show you the way to the storage files (spoiler: they are hidden in /data/system/ and are not available without root), but also explain how MIUI manages passwords at the system level. You will learn why some passwords are saved and others disappear forever after resetting to factory settings, how encryption works in Xiaomi, and what to do if the password manager suddenly stopped displaying stored data.
How to store passwords in MIUI: architecture and levels of protection
Xiaomiβs password management system consists of three key components:
- π Local storage: files in /data/system/ (requires root to access, where passwords are encrypted with a hardware key of the device.
- βοΈ Cloud sync: via Mi Account (if Settings is enabled) β Xiaomi account β Synchronization. Passwords are stored on Xiaomi servers in encrypted form.
- π± Application "Password Manager": a graphical interface for viewing saved data (available in Settings) β Passwords and security).
It is important to understand that not all passwords sync to the cloud. For example, data from Wi-Fi networks and some system applications (like Mi Home) can only remain in local storage. This means that when you reset a device without a backup, you will lose them. Moreover, Xiaomi uses hardware encryption (via Keymaster), so even with root access, it is impossible to extract passwords in readable form without special tools.
Another nuance: in recent versions of MIUI 14+, Xiaomi has begun to integrate Google Password Manager for users with Google services, which means that some passwords can be stored not in the MIUI system storage, but in accounts.google.com. You can check this in Settings β Google β Managing Google Account β Security β Passwords.
Where password files are physically stored: paths and access restrictions
If you want to find password storage files manually, here are the key paths in Xiaomiβs file system (available with root rights only):
| Type of data | Path to file/folder | Storage format | Is it removed when dropped? |
|---|---|---|---|
| Wi-Fi passwords | /data/misc/wifi/WifiConfigStore.xml | XML (encrypted) | Yes. |
| Application passwords (Password Manager) MIUI) | /data/system/credentials.db | SQLite (encrypted) | Yes. |
| Encryption keys | /data/misc/keystore/ | Binary files | Yes. |
| Cloud Backups (Mi Account) | Xiaomi servers (non-local) | Encrypted JSON | No. |
The credentials.db file contains not only passwords but also authorization tokens for applications, making it critical for recovery after a reset. However, even with root access, you canβt simply copy this file to another device β itβs tied to the hardware ID and encryption keys of a particular smartphone.
To view credentials.db content, you need specialized tools like SQLite Browser and table structure knowledge, like app passwords stored in an autofill table, and autocomplete data stored in credentials. But again, without encryption keys, that data would be unreadable.
β οΈ Note: Attempts to modify files into /data/system/ Without understanding the consequences, they can lead to the loss of all saved passwords or even a cyclical reboot of the device. WifiConfigStore.xml Makes it impossible to connect to any Wi-Fi networks before resetting.
Can passwords be extracted without root?
Why Passwords Disappear After Reset: Cleaning Mechanism and How to Avoid It
The main reason for password loss after resetting to factory settings (Settings β About Phone β Settings Reset) is to clean the /data partition.
- π Local password storage (credentials.db)
- π Encryption Keys for Wi-Fi and Applications
- π± Autocomplete settings in the browser and system applications
But cloud data (synchronized via Mi Account or Google) remains intact, but there are pitfalls:
- Not all applications support cloud sync, for example, passwords from banking applications (such as SberBank Online or Tinkoff) are often stored only locally.
- Mi Account does not sync Wi-Fi passwords; they need to be saved separately (e.g., via Google Drive or manually).
- Device-based binding: Some passwords (e.g. for Mi Home or Mi Fit) are tied to MAC-phone address and may not be restored even after logging into the account.
To avoid data loss, make sure to back up before resetting.
Sync passwords with Mi Account (Settings β Xiaomi Account β Sync β Passwords)
Export Wi-Fi passwords through an app like WiFi Password Viewer (requires root)
Save screenshots or export data from MIUI Password Manager
Check that backup in Mi Cloud is created (Settings β About Phone β Backup)
-->
β οΈ Note: If you are using a blocked bootloader, backups through Mi Cloud may not include critical system files, in which case the only reliable way is to manually export passwords or use the passwords. TWRP to create a full backup section /data.
How to Restore Passwords After Loss: Official and Unofficial Ways
If passwords are missing after resetting or updating MIUI, try the following recovery methods (from the simplest to the most complex):
- Check the cloud synchronization: π Go to Settings. β Xiaomi account β Synchronize and enable the password option. π Open the Password Manager (Settings) β Passwords and security β Password Manager and wait for synchronization.
Use Google Password Manager:
If you are logged in to Google, check passwords.google.com β passwords from the Chrome browser and some apps may be saved there.
Recovery from MIUI backup:
If you have backed up to Mi Cloud before reset, return it via Settings β About Phone β Backup β Restore. Note that this will restore all settings, not just passwords.
Manual extraction with ADB (for advanced):
If you have enabled Developer Mode and USB Debugging, you can try extracting files via ADB pull:
adb pull /data/system/credentials.db
adb pull /data/misc/wifi/WifiConfigStore.xmlBut without root and encryption keys, these files will be useless.
Unofficial methods (risky and not guaranteed results):
- π οΈ Use of the TWRP backup and partition recovery /data (requires an unlocked loader).
- π Programs like Mi Account Unlock Tool (not recommended β high risk of blocking the account).
- π± Transferring credentials.db files from another Xiaomi device (only works on identical models with the same version) MIUI).

If you lost your Wi-Fi password but are connected to that network on another device, check it out. QR-code on the router sticker or in the settings of the second device, which will save time to recover.
How to protect passwords from loss: reliable ways to backup
To never lose access to saved passwords, use a multi-level backup system:
- Enable sync with Mi Account: Go to Settings β Xiaomi Account β Sync and activate the Password option. Make sure your Xiaomi account is linked to your current email and phone number.
- Export passwords manually: In the MIUI Password Manager (Settings β Passwords and Security), click on the three dots in the top right corner and select Password Export. You will get an encrypted file that can be saved to Google Drive or to your computer.
- Use third-party managers: Apps like 1Password, Bitwarden, or KeePassDX store passwords in an encrypted container that syncs to the cloud independently of MIUI.
- Create a full backup via TWRP: If you have a bootloader unlocked, install Custom Recovery (TWRP) and back up /data partition. This will save all local passwords, including system ones.
Important: Do not store exported passwords in plain form (such as in notes or on the desktop) use encrypted containers or cloud storage with two-factor authentication.

Even if you use cloud sync, check regularly that passwords are actually saved to Mi Account or Google. For example, after the MIUI update, sync settings may reset.
Myths and Reality: Can Xiaomiβs password store be hacked?
There are often claims online that say, "I hacked Xiaomi's password store in 5 minutes." Let's figure out what's true and what's not.
Myth 1: βYou can extract rootless passwords using ADB.β
Reality: You can copy storage files (credentials.db) through ADB, but without encryption keys (which are stored in /data/misc/keystore/), they will be unreadable. Xiaomi uses hardware encryption at the TrustZone level, so even with physical access to the phone, it is extremely difficult to extract passwords.
Myth 2: If you know PIN-Phone code, you can decrypt all passwords".
Reality: PIN-The screen lock code or pattern lock is not used to encrypt the password store. This is done by using separate keys tied to the device's hardware identifiers.
Myth 3: βThe Xiaomi cloud is unreliable, passwords can be easily stolen.β
Reality: Mi Cloud uses end-to-end password encryption (as does Google Password Manager).This means that even Xiaomi employees can't read your data. However, if your Mi Account is compromised, an attacker will gain access to all synchronized passwords. So be sure to enable two-factor authentication.
Myth 4: βResetting to factory settings completely clears passwords.β
Reality: This is only true for local storage, if passwords are synced to Mi Account or Google, they will recover after being reauthorized, but passwords from Wi-Fi and some system applications are permanently deleted.
Frequent problems with the MIUI password manager and their solutions
Xiaomi users often face the following problems in the work of the password manager:
| Problem. | Possible cause | Decision |
|---|---|---|
| Passwords are not displayed in the manager | Sync is disabled or files are damaged | Enable sync in Mi Account or reset password manager settings (Settings β Applications β App Management β Password Manager β Storage β Clear data) |
| No new passwords are saved. | Insufficient space in /data or permission error | Clear the system cache (Settings β Storage β Cleaning) or restart the device |
| After the MIUI update, passwords disappeared | Resetting synchronization settings or version conflict | Restore data from Mi Cloud backup or log in again to Mi Account |
| Password manager not opening | Error in the system application com.miui.passwordmanager | Remove updates for the app (Settings β Apps β Password Manager β Three Dots β Remove Updates) |
If none of these methods worked, try resetting your security settings:
- Go to Settings β About the phone β Reset settings.
- Select Reset Security Settings (not to be confused with a full reset!).
- After the reboot, log in to Mi Account and check the sync.
β οΈ Note: On certain devices (e.g, POCO F5 or Redmi Note 12) after resetting security settings, you may need to re-attach fingerprints and faces (PIN graphical).
