Where to store passwords in the phone Xiaomi Redmi: the complete guide

Owners of Xiaomi and Redmi smartphones often face a situation when you need to remember a forgotten password from a Wi-Fi network, site or application. Unlike older push-button phones, modern Android devices don't store data as a simple text file, readable in any folder. MIUI HyperOS encrypts credentials by hiding them in special protected memory areas.

Understanding where your keys are located is critical not only for information recovery, but also for digital hygiene. If an attacker gains physical access to an unlocked device, they may try to extract that data. In this article, we will take a closer look at the password storage architecture in the Xiaomi ecosystem, look at Google’s regular tools and Mi Account, and discuss the technical aspects of system storage.

There are several layers of security, cloud synchronized databases, local browser repositories, and the operating core system keys, each with its own access features and backup methods, and we'll go through each layer so you can have full control of your digital security.

Google Smart Lock System Storage

The main and most convenient place to store passwords in your Xiaomi Redmi phone by default is Google Smart Lock (in newer versions of Android, it is transformed into Google Password Manager). This is a cloud storage that synchronizes data between your account and your device. When you enter your login and password on any site in the Chrome browser or in the application, the system suggests saving the combination.

This data is accessed through system settings, making the browsing process easy for the average user, so you can not only see the saved bundles, but also edit them, delete them or export them, and it is important to understand that this feature requires active synchronization of the Google account on the device.

If you change your phone or complete a reset, just log in to your Google account and all passwords automatically pull up from the cloud, eliminating the need to manually enter data on each site again, but if sync has been disabled, the data can only remain in the local browser cache.

⚠️ Note: Deleting your Google account from your device without first checking sync may result in the loss of all passwords stored in the cloud if they were not copied to Mi Cloud or elsewhere.

The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic remains the same for all Xiaomi smartphones.

Local storage Mi Cloud and Xiaomi Account

The second important layer of security in Xiaomi devices is the manufacturer’s own cloud, Mi Cloud. Users who have registered Mi Account often do not even realize that their passwords from Wi-Fi and some system settings are duplicated here, this is an independent loop from Google, which is especially useful in regions where Google services can work unstable, or when using Chinese versions of firmware.

Storing data in Mi Cloud allows you to restore access to Wi-Fi networks even after completely flashing your smartphone if you log in to the same account. The system encrypts the data transmitted, but the level of trust in third-party cloud storage should always be balanced. Unlike Google, where site passwords are a priority, Mi Cloud focuses more on system settings and contacts.

Check what exactly syncs in your case, you can through the account menu. Here you should pay attention to the item “Passwords”, which can contain both data from sites (if the corresponding option is enabled in the Mi browser) and access keys to the Xiaomi ecosystem itself.

You should pay special attention to the fact that when you delete your Mi Account from your device, the data from the cloud does not disappear, but the local copy can be cleared depending on the security settings you choose.

Passwords in Google Chrome browser

Most Xiaomi Redmi users use Google Chrome as their primary surfing tool, and it has its own system-menu-independent password store, though it is closely integrated with a Google account, and it is where forgotten combinations from social media and email boxes are most often stuck.

To find the stored data, you don't have to go into the deep settings of the phone, just open the browser itself and go to the password management menu, and here the interface is more detailed: you can see the date of the last password change, and also receive notifications if any of your passwords were found in the database of leaks.

Chrome’s Password Checker is a powerful security tool that automatically scans saved bundles and tags those that are too simple, repetitive, or compromised, allowing you to quickly update your security for important accs right from your phone.

It is important to note that deleting browsing data history in Chrome does not always delete saved passwords unless the appropriate tick is selected.

Password Manager in MIUI and HyperOS

The MIUI shell and the new HyperOS have a built-in tool called Password Manager, a native application that tries to combine the storage of Wi-Fi passwords, stand notes and application credentials, and can be found through a search in settings or in the Tools folder.

This manager is often used to store passwords from Wi-Fi networks that the phone was connecting to. Unlike Google, which stores them in an account-based connection, Xiaomi can keep a local copy of Wi-Fi encryption keys in a secure memory area. To view the password from the current or previously connected network, it is often enough to click on the eye icon and pass biometric authorization.

In newer firmware versions, the controller’s functionality is expanded, and it can now offer complex password generation and automatic substitution in application input fields, competing with Google Autofill. You can switch between autocomplete providers in the basic system settings.

It is worth considering that when switching from MIUI to another shell (for example, pure Android or iOS), exporting data from Xiaomi’s native controller can be difficult, since the storage format is specific.

Third-party password managers and their work at Xiaomi

Many users prefer not to trust the storage of sensitive data, neither Google nor Xiaomi, using specialized applications like KeePass, Bitwarden or 1Password. On Redmi smartphones, such applications work stable, but require the correct setting of permissions.

The aggressive MIUI energy saving system may attempt to kill the background process of the password manager, causing autocomplete to stop working at the right time. To avoid this, you need to manually configure the application: disable battery saving and fix it in memory.

The advantage of third-party solutions is end-to-end encryption, and even if someone gets access to your phone manufacturer's cloud account, without a master password, they can't decrypt the database -- a level of security that often exceeds standard offerings.

💡

For stable third-party password managers on Xiaomi, add the app to the autoboot and select No Limits mode from the Battery and Performance menu.

Installing a third-party manager requires care when you first set up. Make sure you turn on Autofill Service in your system settings, selecting your application as default. Without that, you'll have to copy your password manually every time.

Technical aspects: root access and system files

For advanced users with SuperUser (Root) rights, the question of where passwords are stored is literally answered in specific files of the file system, but they are not accessible at the Linux kernel level on which Android is based.

The main file that stores passwords from Wi-Fi networks is on the way /data/misc/wifi/wpa_supplicant.conf. In newer versions of Android (starting with the 10-The storage structure has changed and the data can be scattered across different databases in the /data/misc/apexdata, Which makes manual search extremely difficult.

Passwords from applications and sites in Google’s system storage are stored in an encrypted credentials.db database located in the directory /data/data/com.android.providers.settings/databases/. The keys to decrypt this database are stored in a secure KeyStore storage, tied to a specific device and user.

⚠️ Attention: Getting root rights violates the integrity of Android security, which can lead to blocking of banking applications (Google Pay / Wallet) and resetting. DRM-keys, which will worsen the quality of content playback in streaming services.

Manipulating system password files without proper knowledge can lead to a phone “bricking” or endless reboot cycle. If you don’t understand how the ext4 or f2fs file system works, it’s better to limit yourself to standard browsing methods through settings.
