Where Xiaomi stores passwords from Wi-Fi, accounts and applications – full analysis

If you've ever forgotten your Wi-Fi, Mi-account, or saved usernames in a Xiaomi smartphone browser, you've probably wondered: Where exactly does your device store that information? Unlike iOS, where data is securely isolated in Keychain, or Windows with its Credential Manager, MIUI organizes password storage in its own way, with nuances that are important to understand for both security and access recovery.

In this article, we will discuss in detail:

• 🔐 Where to store passwords in memory of Xiaomi devices (from Redmi Note 10 to Xiaomi 14 Ultra)
• 🛡️ How MIUI Encrypts sensitive data and why it is difficult to extract it without root rights
• 📱 How to legally access saved passwords (including: ADB and backups)
• ⚠️ Risks of using third-party utilities to extract passwords and how not to run into scammers

Separately, we will focus on myths: for example, many users mistakenly believe that passwords from Wi-Fi are stored in plain form in a file. wpa_supplicant.conf — This is true only for Android versions below. 10, a in modern firmware MIUI 14/15 And we're also debunking the myth of Mi-account hacking through an engineering menu, which is technically impossible without physical access to the eMMC chip.

Warning: all information in the article is informative, unauthorized access to someone else's passwords is punishable by law (Article 272 of the Criminal Code of the Russian Federation), We talk about storage mechanisms solely for the recovery of our own data.

1.Where Xiaomi Stores Wi-Fi Passwords: The Evolution of Methods in MIUI

In older versions of Android (up to) 9 Wi-Fi passwords were actually stored in a text file /data/misc/wifi/WifiConfigStore.xml or wpa_supplicant.conf. You can read them without rooting, using them. ADB with shell rights, but with exit MIUI 11 (Android-based 10) Xiaomi switched to encrypted storage in the database WifiConfigStore.db, located on the way:

/data/misc/apexdata/com.android.wifi/WifiConfigStore.xml


/data/misc/apexdata/com.android.wifi/WifiConfigStore.db

Now, the data is protected by a key tied to KEEMASTER, which means that even with physical access to the file, you can't decrypt passwords without:

• 🔓 Root rights (to extract the key from the /data/misc/keystore)
• 📱 Unlocked bootloader (for modification of system partitions)
• 🔧 Specialized utilities like WiFi Password Viewer (only work on rooted devices)

Important: In MIUI 14+, Wi-Fi passwords are additionally linked to your Mi Account if sync is enabled, meaning that when you reset your phone, you can only restore them through login to the same account.

App and browser passwords: how MIUI integrates with Google Smart Lock

Saved logins and passwords in Chrome, Mi Browser or third-party apps (such as Facebook, Instagram) are stored in two places:

1. Google Smart Lock (if sync with Google account is enabled): 🌐 Data is encrypted and sent to Google servers (available at passwords.google.com) 🔒 The local copy is stored in /data/data/com.google.android.gms/databases/phenotype.db (coded)

MIUI Local Storage

• 📁 File. /data/system/users/0/accounts.db (contains authorization tokens)
• 🗝️ Directory /data/data/com.miui.securitycenter/databases/ (passwords from system applications)

To extract this data without root, there is a legal way to use it. ADB-commands to create a backup:

adb backup -f backup.ab com.google.android.gms


adb backup -f backup.ab com.android.providers.settings

However, it is impossible to decrypt the resulting.ab file without a password - it is protected by AES-256 with a key attached to the device.

⚠️ Note: Applications like Mi Password Manager (built-in) MIUI password manager) store data in encrypted form in /data/data/com.miui.passwordmanager/. Even with root, decrypting them requires knowledge of the user’s master password.

Mi-account password: why you can't "pull" it out of your phone

The Mi-account account is a separate story, and its password is never stored on the device explicitly.

• 🔑 Only the authorization token is saved on the phone (in /data/system/users/0/accounts.db), time-limited.
• 🔐 The password itself is hashed by algorithm PBKDF2 with salt and sent to Xiaomi servers (bypassing the device).
• 📱 When you reset the phone, the token is reset, and it requires the original password (or confirmation via a confirmation via a secure device) to be unlocked. SMS/email).

This means that:

• ✅ You can only restore access to Mi-account through official channels (account.xiaomi.com).
• ❌ There are no legal ways to extract a password from a phone’s memory – even with root and engineering menus.
• ⚠️ All the instructions on the Internet about resetting Mi-account through EDL-The mode or Fastboot is either outdated (worked until 2019) or is a fraud.

💡

If you forget your Mi-account password but have your phone number or email attached to it, use the recovery function on the official website, which works more quickly than trying to cheat the system in 90% of cases.

4. How to legally extract saved passwords without root

If you need to recover your own passwords (like those from Wi-Fi or apps), there are a few safe ways to do this:

Method 1: Backup through Mi Cloud

If your device is synced to Mi Cloud, passwords from Wi-Fi and some applications can be restored:

1. Go to i.mi.com and log in.
2. Select the Devices section → [Your phone] → Backup copies.
3. Download the archive and find the WiFiConfigStore.bak file (decryption required).

Method 2: ADB-teaming

With ADB, you can back up your system settings, including some passwords:

adb shell


su




cp /data/misc/wifi/WifiConfigStore.xml /sdcard/




exit

Without root, however, the file would be empty or encrypted, and full access would require Magisk or a similar tool.

Install ADB on PC (download from [developer.android.com](https://developer.android.com/studio/releases/platform-tools)

Enable USB debugging in your phone settings (Settings → About Phone → MIUI version (7 times) → Developers → USB debugging)

Connect your phone to your PC and confirm your trust in your computer

Check the availability of the device by the adb device team-->

Method 3: Use of official instruments

For Wi-Fi passwords:

• 📱 On the phone go to Settings → Wi-Fi, tap on the saved network and select Share Password (required) PIN-code).
• 🖥️ On Windows, you can view the password through the Network Management Center → Change of adapter parameters → Properties of wireless network → Security (if the phone has previously connected to this PC).

⚠️ Note: Any apps from Google Play that promise to show rootless passwords (such as the WiFi Password Show) or don’t work on the Internet. MIUI 12+, Or they're phishing. Don't put Mi-account data in them!

5. Risks of using third-party utilities to extract passwords

The Internet is full of suggestions like “crack Xiaomi password in 5 minutes” using programs like Mi Account Unlock Tool, Xiaomi Tool V2 or EDL Authorizer.

• 🕵️ Phishing: Many “tools” ask for a username/password from Mi-account, and then steal an account.
• 💻 Malware: Files with the.exe or.bat extension often contain Trojans (e.g., RedLine Stealer).
• 🔧 Brick Devices: Misuse EDL Fastboot can turn a phone into a brick".
• 📵 Lockdown IMEI: Xiaomi may block the device for attempting unauthorized access.

In 2023, Redmi Note 11 users complained massively about Mi-account blocking after using the "Mi Unlock Tool Pro" (fake software), and were only able to restore access through the use of purchase checks.

If you really need to extract passwords, use only official methods:

• 🔄 Recovery via Mi Cloud or Google Smart Lock.
• 📱 Contact the Xiaomi service center with documents on the phone.
• 🔓 Legal utility for rooted devices (e.g. Titanium Backup).

💡

No utility can bypass two-factor authentication Mi-account. If your account is enabled by linking to your phone number or email, recovery is possible only through official channels.

6.How to Protect Your Passwords on Xiaomi: Security Guidelines

To minimize the risk of password leakage:

1. Turn off autocomplete passwords in settings: Settings → Passwords and Security → Autocomplete → Disable.
2. Use a password manager (such as Bitwarden or 1Password) instead of the one built into MIUI.
3. Set up two-factor authentication for Mi-account and Google.
4. Regularly update MIUI – new versions fix vulnerabilities (for example, MIUI 15 closed the hole with the extraction of tokens through ADB).
5. Don't install it. APK from unknown sources, they may steal data from the /data/data/.

For advanced users:

• 🔐 Install Magisk and XPrivacyLua to restrict application access to password storage.
• 📱 Use encrypted storage (like VeraCrypt) for backups.

Critical information: MIUI 14+ adds Privacy Protection, which blocks access to system files even with root rights, and you need to manually patch build.prop to disable it.
