The question of where exactly in the Android operating system installed on Xiaomi devices, credentials are stored, worries users for various reasons: some want to check the saved Wi-Fi key, others are trying to restore access to the account after a reset, and still others are concerned about leakage of confidential information. Understanding the storage architecture in the shell of MIUI or HyperOS is the first step to competent management of the digital security of your gadget.
The password storage system in the Chinese brand’s smartphones is built on a multi-level model that depends on how you store data. Android local storage, Google cloud services and the proprietary Mi Cloud are the three main areas where your logins and access keys can be located. It is important to distinguish between these levels, since access is carried out by different methods, and the risks of data loss are also significantly different.
In modern firmware versions, the priority shifts to cloud sync, which makes data available from any device, but requires a constant connection to the Internet. However, local databases have not gone anywhere and continue to function in the background, ensuring that applications work even when there is no network, and let’s take a detailed look at each of these levels, so you know exactly where to look in a particular situation.
Google Passwords System Storage
The most common place to default passwords on Xiaomi phones is Google Passwords. Starting with certain versions of Android, Google has moved password saving from shared account settings to a separate, more secure application to improve the security and ease of managing credentials associated with your Gmail account.
To find the stored data, you need to go to the phone's security settings. The path may vary slightly depending on the version. MIUI, But it usually looks like this: Settings. → Google → Auto-filling → Autocomplete by Google → Passwords: This displays a complete list of sites and applications that have logged in, and access to the contents of each location is protected by biometrics (fingerprint or Face). ID) or PIN-screen-opening.
The feature of this storage is its deep integration with the Chrome browser and autocomplete system. If you log in to the site in the browser, the system will offer to save the data. Synchronization is instant, so when you buy a new Android phone, just enter the same Google account.--WIDGET:keypoint:Google Passwords passwords are encrypted and cannot be read by Google or Xiaomi employees without your authorization.-->
Local storage Mi Passwords (Mi Cloud)
Xiaomi, Redmi and Poco smartphone owners have access to the company’s own cloud service, Mi Cloud. Unlike Google, which stores data globally, Mi Passwords often works as a local manager with the ability to sync through a Mi Account. It is a separate ecosystem that can duplicate or replace Google’s features depending on your settings when you initially activate the device.
You can find this data through the System Security app or in the Mi Account settings. The path usually looks like this: Settings → Mi Account → Mi Cloud → Passwords. In some regions and firmware versions, this section may be called “Mi Passwords.” It stores not only passwords from sites, but also data from the Wi-Fi networks to which the phone was connected, as well as the keys for two-factor authentication.
⚠️ Note: If you reset your phone to factory settings and don’t log in to Mi Account immediately, local copies of passwords that aren’t synced to the cloud will be permanently lost.
A unique feature of Mi Passwords is the ability to generate robust character combinations right in the input interface.The system offers autocomplete in apps and browsers, even if they are not Google products.This creates a convenient alternative for users who do not trust US corporations or are just used to the Xiaomi ecosystem.
What happens when you delete your Mi Account?
Access to system files through Root rights
Advanced users with superuser rights (Root) can access the deep layers of the Android file system. This is where password databases are physically stored in encrypted form. The standard path to the system key store is at /data/misc/keychain/ or in the browser database /data/data/com.android.browser/databases/.
Files like credentials.db or webview.db are protected by file system-wide encryption (FBE — File Based Encryption means that without unlocked bootloader and the correct encryption keys tied to a particular device and PIN-In the code of the owner, these files are just a collection of meaningless bytes.
- 🔒 Access to section /data/ Only possible with Root rights or through ADB debugging.
- 📂 Database files usually have the.db or.sqlite extension.
- 🛡️ Encryption tied to hardware security module (TEE) processor.
Attempting to copy these files to another phone without first decrypting them will not work. Android’s system limitations are designed to prevent an attacker from accessing sensitive data even when physically retrieving memory, so for the average user, this method is only relevant if data is recovered by digital forensics specialists.
💡
Use Root-enabled file managers like MiXplorer or Solid Explorer to safely browse system directories, if you have the appropriate permissions.
Passwords in Chrome and Mi Browser
Most users save passwords directly in the browser they use. Xiaomi smartphones have two main browsers preinstalled: Google Chrome and Mi Browser. Each has its own, independent storage. If you saved data in Chrome, it is useless to search for it in the Mi Browser settings, and vice versa.
In Google Chrome, you can manage it through a three-point menu: Settings → Passwords. You can view, change or delete saved login password pairs. The browser also offers a password check feature for network leaks. Mi Browser works similarly, but stores the data in its Mi Account cloud profile if synchronization is enabled.
| Characteristics | Google Chrome | Mi Browser |
|---|---|---|
| Account binding | Google Account | Mi Account |
| Synchronization | Global (all OSs) | In the Xiaomi/Android ecosystem |
| Biometry | Supported | Supported |
| Export of data | CSV file | CSV file (through settings) |
Automatic save is convenient, but it requires attention: if you click Save on someone else’s device or incognito mode (which is technically impossible, but often confused with normal mode), the data may go wrong.
Third-party password managers
If Xiaomi or Google’s built-in tools don’t suit you, many users turn to third-party solutions, apps like Bitwarden, 1Password, KeePass or LastPass create their own, isolated storage, in which case the question “where passwords are stored” has a simple answer: on the servers of the service you choose or in an encrypted file inside the phone’s memory.
These apps work on a master password principle, where you remember one complex combination, and the program generates and stores unique keys for each site. In a Xiaomi phone, they integrate into the autocomplete system. When you open the input field, Android asks permission from the installed password manager to substitute data.
☑️ Criteria for choosing a password manager
The advantage of third-party solutions is that they are independent of the phone manufacturer: If you decide to switch from Xiaomi to iPhone or vice versa, your passwords will remain with you, you just need to install the application and enter the master code. Local storage of such applications (for example, the KeePass database) can be in the phone’s memory, but without a master password, it is useless for an attacker.
Synchronization problems and their solution
A common problem with Xiaomi users is to desynchronize passwords between devices: you save a password on your phone, but it doesn’t appear on your tablet or computer.This may be due to aggressive energy savings in the MIUI shell, which kills background synchronization processes to save battery life.
To fix this, you need to set up autorun for Google and Mi Cloud services. Go to Settings → Apps → Autorun and make sure the switches opposite Google Play Services and Mi Cloud are active. Also, in the Battery section, for these applications, select No Limits mode, which will allow the background services to work correctly.
⚠️ Note: Two-factor authentication (2FA) It can block sync if you change your password on one device but don't update it on others, and the security system will consider trying to sync with old data as suspicious activity.
Another reason could be errors in date and time, if the device is timed down, SSL-The certificates will not be checked and the connection to the password server will be broken. → Date and time.
Export and backup of data
Regular password backup is a critical digital hygiene procedure. No cloud service offers a 100% guarantee, and there is always a risk of account locking. Google Passwords and Mi Passwords provide a CSV data export feature. This file contains all your logins and passwords in plain text.
For export to Google: go to Settings → Google → Passwords, click on a gear or three dots, and select Export Passwords. The system will warn about the risks and ask for biometric confirmation. The file will be saved in the Downloads folder with a name like passwords.csv.
- 📂 Format CSV You can open it in any text editor or Excel.
- ⚠️ File is not password protected, keep it in an encrypted archive.
- 🗑️ After use, be sure to delete the export file from the phone's memory.
The export file contains passwords in plain form, so transferring this file to messengers or storing it in the public cloud is equivalent to transferring the keys to the apartment to unauthorized people, and use this method only to transfer data to a reliable external medium or to an encrypted archive.
💡
A backup copy of passwords in CSV format should be stored on an offline medium (flash drive, external drive) in a physically safe place.
