Where Xiaomi stores application passwords: system storage and access methods

Have you ever wondered where app passwords go when you log in to a Xiaomi or Google account? Why do some services remember login data and others require re-entry? In Xiaomi devices (as in any Android smartphone), application passwords are stored in several secure areas of the system, but access to them is strictly limited. This article will help you understand where credentials are stored, how they are encrypted and whether they can be retrieved without risk to security.

Itโ€™s important to understand that MIUI uses both standard Android mechanisms and proprietary password storage solutions, such as Mi Account data being processed separately from third-party passwords, while some services (like Google Smart Lock) sync credentials to the cloud, while others store them locally in encrypted form, and weโ€™ll analyze all key storages, their vulnerabilities, and legal ways to manage passwords.

1. Standard password storage in Android and MIUI

The Android operating system provides several built-in mechanisms for storing application passwords, the main ones being:

  • ๐Ÿ” Android Keystore is a hardware store of cryptographic keys used to encrypt passwords, and only system processes and applications with appropriate permissions can access it.
  • ๐Ÿ“ SharedPreferences are application settings files where access tokens can be stored (but not the passwords themselves in plain form, /data/data/com.package.name/shared_prefs.
  • ๐ŸŒ Google Smart Lock is a cloud-based service that syncs passwords between devices, only works when logged in via a Google account.
  • ๐Ÿ”„ Account Manager is a system service that manages accounts (including Mi Accounts) that stores tokens, but not passwords themselves.

Another layer is added to MIUI, Mi Cloud, which can back up some application data (such as Mi Home or Mi Fit passwords), but most third-party apps (such as VK, Telegram, bank clients) store passwords in their own containers encrypted with Android Keystore.

Important: Passwords in plain form are never stored in the system, and even if you use the Save Password function in a browser or application, the system only stores a hash or an encrypted version that cannot be read without special keys.

๐Ÿ“Š Where do you usually save passwords?
In the browser (Chrome, Mi Browser)
Password Manager (Keepass, 1Password)
In the phone notes
I don't keep it anywhere.

2.Where exactly Xiaomi stores passwords from system applications

Xiaomi system applications (e.g. Mi Account, Mi Home, Mi Fit) use their own credentials storage mechanisms.

AnnexType of dataStorage areaCan I get it out?
Mi AccountAccess token/data/system/users/0/accounts.dbOnly with root rights.
Mi HomeLocal settings of devices/data/data/com.xiaomi.smarthome/shared_prefsPartially (configs only)
Mi BrowserSave site passwords/data/data/com.android.browser/databases/webview.dbYes, through export.
Telephone/ContactPasswords. SIM-map, PUKChip. SIM-map / /data/data/com.android.phoneNo (only through operator)

Root rights are required to access these files because they are in a protected area. /data/data/. Even with superuser rights, passwords are usually encrypted and decrypting them requires knowledge of the algorithms used by Xiaomi.For example, Mi Account tokens are tied to a unique device identifier (MIUI ID), Which makes them useless on another phone.

โš ๏ธ Warning: Attempting to extract passwords for system applications without official tools may result in the blocking of your Mi Account. Xiaomi is actively fighting unauthorized access to its services, and suspicious activity (such as frequent requests to accounts.db) can provoke a temporary blocking of the service.

3. How third-party apps store passwords on Xiaomi

Google Play apps (like VK, Instagram, and banking customers) store passwords in different ways, most of which follow Googleโ€™s guidelines and use:

  • ๐Ÿ”‘ Android Keystore for data encryption, for example, a password is encrypted with a key stored in the Trusted Execution Environment hardware module (TEE).
  • ๐Ÿ“ฑ Local databases (SQLite) in the application folder, /data/data/com.vkontakte.android/databases. Passwords are stored in encrypted form.
  • โ˜๏ธ Cloud backups (if sync is enabled) such as Google Smart Lock or the app's own servers.

Some apps (like Telegram) store only session keys, not the passwords themselves, which means that once you reinstall the app or reset your phone, youโ€™ll have to log in again, while others (like Chrome) offer to save the password to Google Smart Lock, allowing you to restore it to a new device.

Example of a path to the Chrome database where passwords are stored:

/data/data/com.android.chrome/app_chrome/Default/Login Data

To view saved passwords in Chrome, you do not need root rights โ€“ just go to Settings โ†’ Passwords in the browser itself.

๐Ÿ’ก

If you use Mi Browser, export saved passwords through Settings โ†’ Additionally. โ†’ Passwords. โ†’ Export, file will be protected. PIN-device-code.

4. Can passwords be restored without root rights?

Without a superuser's rights, it's impossible to extract passwords for most applications, but there are a few legal ways to do this:

  1. Recovery via Google Smart Lock If you have previously saved passwords in Chrome browser or applications that support Smart Lock, they can be restored on a new device after logging in to the same Google account.
  2. Exports from password managers Applications like 1Password, KeePassDX or the built-in MIUI manager (if used) allow you to export passwords to an encrypted file.
  3. Most services (social networks, banks) offer the function "Forgot your password?" with recovery by email or SMS.

For system applications, Xiaomi (such as Mi Home) sometimes helps to reset the application settings through Settings โ†’ Apps โ†’ [Application] โ†’ Storage โ†’ Clear the data. After that, the application will prompt you to log in again, but the old data of smart home devices can be lost.

โš ๏ธ Warning: Some โ€œhackedโ€ apps from third-party sources (not Google Play) may steal passwords stored in Android Keystore. APK-files only from verified sources and monitor application permissions (e.g. access to the android.permission.READ_LOGS should beware).

5 Risks and Vulnerabilities: How to Protect Your Passwords

While MIUI and Android provide strong password protection mechanisms, there are risks of password leakage:

  • ๐Ÿ› ๏ธ Root access: Installing unofficial firmware or obtaining root rights could weaken Android Keystore protection.
  • ๐Ÿ“ฑ Device theft: If the phone is not locked PIN-By code or fingerprint, an attacker can access saved passwords through a browser or manager.
  • ๐Ÿ”— Phishing applications: Fake programs (such as โ€œcache cleanersโ€) may request permission to read data from other applications.
  • โ˜๏ธ Cloud Services Leaks: If you sync passwords through Mi Cloud or Google Smart Lock, their security depends on account security.

To minimize the risks:

  1. Use complex ones. PIN-codes or biometric authorization to unlock your phone.
  2. Enable two-factor authentication for Mi Account and Google.
  3. Check the list of applications with access to the android.permission.GET_ACCOUNTS In Settings โ†’ Annexes โ†’ Permits.
  4. Avoid storing passwords in Notes or SMS โ€“ these data are easy to extract even without root rights.

7. Frequent errors and myths about password storage

There are many misconceptions about password storage on Xiaomi, and we'll look at some of the most common ones.

  • ๐Ÿšซ Myth 1: "Passwords are stored in the passwords.txt file in the root folder. Reality: Passwords are never stored in plain form. Even in files. shared_prefs or databases they're encrypted.
  • ๐Ÿšซ Myth 2: "Resetting your phone to factory settings removes all passwords from the cloud." Reality: Reset only deletes local data. Passwords synchronized with Google Smart Lock or Mi Cloud will remain in the cloud.
  • ๐Ÿšซ Myth 3: "Root rights allow you to see all passwords in plain sight." Reality: Root gives you access to encrypted files, but to decrypt them you need keys from Android Keystore, which are tied to the hardware.
  • ๐Ÿšซ Myth 4: "Xiaomi is transferring passwords to China." Reality: There's no evidence that MIUI Sends passwords to Xiaomi servers, but system applications (such as Mi Home) can sync data to Mi Cloud if allowed in the settings.

If you suspect that your passwords are compromised, change them immediately and check your device for malware using Google Play Protect or Malwarebytes.

No legal application can extract passwords from other programs without root rights, and all suggestions to "crack" or "recover" passwords without access to an account are fraud.

FAQ: Frequent questions about passwords on Xiaomi

Can I recover my Mi Account password if I forgot my email?
Yes, but only if your account is linked to a phone number. Go to the recovery page account.xiaomi.com/pass/retrieve and select the recovery option via SMS. If the number is also lost, contact Xiaomi with proof of ownership of the device (IMEI, purchase check).
Where are the Wi-Fi passwords stored on Xiaomi?
Passwords from Wi-Fi networks are stored in a file /data/misc/wifi/WifiConfigStore.xml. You can view them without root rights through Settings โ†’ Wi-Fi โ†’ [Network] โ†’ Share (required) PIN-Device code. To extract all networks, you need root rights and an application like WiFi Password Viewer.
Why do some apps not require re-entry after a phone reset?
This happens if: The app uses Google Smart Lock and you are logged in to the same Google account. App data has been restored from a Mi Cloud or Google Drive backup. App stores an access token (not a password!) in a secure storage that remains valid after reset. Bank applications and instant messengers (such as Telegram) usually require re-authorization.
Can I transfer passwords from one Xiaomi phone to another?
Yes, in several ways: Through Google Smart Lock: log in to the new device in the same Google account. Through Mi Cloud: enable sync in Settings โ†’ Xiaomi Account โ†’ Mi Cloud โ†’ Sync. Through export/import in password managers (e.g. KeePassDX). System applications (e.g. Mi Home) may require re-authorization.
How to protect your passwords if your phone is stolen?
Do these things immediately: Remotely lock your device via Find Device (for Mi Account) or Find My Device (for Google); Change passwords from critical services (banks, social networks, email); Revoke access to accounts from the stolen device in the security settings of Google and Mi Account; If your phone has saved passwords in your browser, delete them through the web version of Google Password Manager.
