Owners of Xiaomi, Redmi and POCO smartphones often face the need to remember the saved password from Wi-Fi, a site or an application. The question of where exactly this data is stored in the Android system becomes especially relevant when changing a device or trying to restore access to an important resource. Modern shells MIUI and HyperOS use complex encryption mechanisms, so simply “open a folder and read a file” will not work without special knowledge.
The credentials of the Chinese brand have evolved with versions of the operating system. While there were vulnerabilities that allowed you to root and extract password hashes from system files, security is now significantly enhanced. Key data is encrypted by default and linked to a unique device ID or Google account, making direct copying of the database useless without authorization.
In this article, we will take a look at all the possible locations where your usernames and passwords may be located.We will look at standard cloud storage, local password managers, system partitions with increased privileges and data export methods, this knowledge will help you not only find the forgotten combination of characters, but also assess the level of security of your gadget from unauthorized access.
Google Password Manager Cloud Storage
The most common place where passwords are stored on Xiaomi is Google’s built-in password manager. Since the vast majority of devices are running Android, the default system suggests that you save the data you entered to your Google account, which provides synchronization between your phone, tablet and computer if you use the Chrome browser or Android system on different gadgets.
To view saved records, you need to go to security settings. The path usually looks like: Settings → Google → Autocomplete → Google Password Manager. This displays a list of all the sites and applications for which you previously saved credentials. Access to this list is protected by biometrics (fingerprint or Face ID) or screen unlock pin, which is an important element of protection.
⚠️ Note: If you reset your Google account settings or forget your password, it may be impossible to recover your stored data without a procedure to restore your account through trusted devices.
The convenience of using this method is deep integration with the system. When you try to log in to a site in a browser or in an application, Android will automatically prompt you to substitute the saved password. However, if you use multiple Google accounts, make sure that you choose the one that was originally used to save data.
Local storage Mi Cloud and Xiaomi Account
The second most important element of the ecosystem is the manufacturer’s own cloud, the Mi Cloud, which owners of Xiaomi, Redmi and POCO devices often ignore this service, preferring Google solutions, but it has its own powerful tools for synchronizing data, in particular, it can store passwords from Wi-Fi networks, notes and data of some system applications.
To check for stored data, you should open the Security app or go to Settings → Mi Account → Mi Cloud. Unlike Google, which stores passwords as an encrypted database synchronized in the background, Mi Cloud often acts as a backup of system settings, which is especially useful if you change your phone to a new one within the Xiaomi ecosystem.
While Google uses end-to-end encryption for passwords, Mi Cloud’s policies may depend on server region and local law, so critical data such as passwords from banking applications or crypto wallets is better duplicated in dedicated secure storage rather than relying solely on vendor cloud synchronization.
💡
Check sync status regularly in Mi Cloud to make sure your data is actually stored on the server, rather than hanging in a download queue.
Third-party password managers and their work at MIUI
Many users choose not to trust the storage of sensitive information to corporations and install third-party applications. Xiaomi smartphones with a shell MIUI or HyperOS popular solutions such as KeePass, Bitwarden, 1Password and Enpass. These programs create a local or cloud database that is protected by a master password known only to the owner.
The feature of such applications on Xiaomi devices is aggressive battery optimization. The system can automatically “kill” the process of synchronization or autocomplete, considering it to be an extra load. To ensure that the password manager works correctly, you need to manually configure permissions: prohibit autostart, turn on work in the background and add the application to the power saving exceptions.
The advantage of using third-party solutions is cross-platform. You can access your password database not only from a Redmi phone, but also from an iPhone or a Windows or Linux computer. Local database storage (like KeePass) provides maximum control: you have the database file, and even if you hack the developer servers, your data will remain safe unless you hand over the master password.

System Files and Root Access
For advanced users with superuser rights (Root), it is possible to view system files where password hashes are technically stored. In the classic Android architecture, this data is in the section /data/, It's not readable without privileges: wpa_supplicant.conf (for Wi-Fi and various SQLite databases.
Getting root rights on modern Xiaomi smartphones is a complex procedure that requires unlocking the bootloader. Once the superuser unlocks and installs the rights (for example, through Magisk), it becomes possible to access the file system through root-enabled file managers such as Root Explorer or MixPlorer. However, modern versions of Android use full-disk encryption (FDE/FBE), so even with root rights, reading some areas can be difficult without unlocking the device.
It is important to understand the risks associated with obtaining root access. This not only voids the warranty, but also violates the integrity of the security system. Bank applications and payment systems (Google Pay, Mi Pay) can stop working or require complex manipulations with the masking of root rights.

Comparison of data storage methods
To choose the best way to manage access, you need to compare the options available on key parameters: convenience, security and availability. Below is a table showing the differences between the main methods of storing passwords on Xiaomi devices.
| Storage method | Level of security | Usability | Network dependency |
|---|---|---|---|
| Google Password Manager | High (2FA, encryption) | Maximum (autofill) | Required for synchronization |
| Mi Cloud | Medium/High | High (in ecosystem) | Required for synchronization |
| Third-party annexes | Very high (master password) | Medium (requires a separate entrance) | Optional (local base) |
| Root files | Low (risk of hacking) | Low (complicated access) | Not required |
Analyzing the table, we can conclude that for most users, the best choice is a combination of Google Password Manager for everyday tasks and a specialized application with a master password for mission-critical data. Using root access solely for viewing passwords is impractical due to high security risks.
💡
The balance between convenience and security is key: Cloud services are convenient but require trust from the provider; on-premises databases are safer but less convenient to use on a daily basis.
Restoring access and security advice
If you forget your manager's master password or lose access to your account, the recovery process can be difficult. In the case of Google and Mi Account, there are recovery procedures through backup email addresses and phone numbers. However, if you used a third-party app with local storage and forgot your master password, the data can be lost forever, as developers often do not have the technical ability to reset encryption.
To ensure maximum security on smartphones, Xiaomi recommends using two-factor authentication (2FA) wherever possible. Even if an attacker gains access to your device, additional code from an SMS or authenticator application will be a serious obstacle, and it is also worth regularly auditing saved passwords, removing old ones and replacing weak combinations with complex ones.
⚠️ Warning: Never store password screenshots or document photos in a shared gallery.A malicious app with access to media files can easily copy these images and share them with third parties.
Regular updates to MIUI/HyperOS and all password manager applications are critical. Updates often contain security patches that close vulnerabilities through which hackers could access the credential store. Ignoring updates leaves your smartphone open to known attacks.
