Modern Xiaomi smartphones, which run on MIUI and HyperOS shells, are equipped with powerful security systems that automatically remember the data you enter. This is convenient for everyday use, but sometimes you need to delete the saved password.
The cleaning process depends on whether the access key is stored in a Google account, in the Mi Cloud cloud, or in the Wi-Fi system buffer. In this article, we will discuss all possible scenarios in detail and show you how to securely delete login data. It is important to understand that deleting passwords from cloud storage syncs with all devices where you log in.
Delete passwords through Google Password Manager
The main data storage for most Android users is Google. To remove the saved password on Xiaomi, you need to consult the system security settings. This method is relevant if you used Google autocomplete when logging into sites or apps.
The navigation in the menu can vary slightly depending on the Android version and the MIUI shell. Usually the path is as follows: open Settings, search the Google section, then go to Autocomplete and select Autocomplete from Google. Here you will see the Google Password Manager button.
In the list that opens, find the site or app you want, the system will require proof of identity through a fingerprint or a pattern lock, and after you log in to the site card, click the "Delete" button, which will irreversibly remove the login and password bundle from the Google cloud.
⚠️ Note: Deleting the password from the Google Manager will remove it from all devices synced to that account. Make sure you remember the login details or you no longer need them.
You can use direct search to clean up quickly, and type "password manager" into the settings search bar to get to the desired section instantly, bypassing long menu browsing.
Cleaning up data in Mi Cloud (Xiaomi Cloud)
Redmi and POCO smartphone owners often use the manufacturer's own cloud service. If you've previously enabled synchronization of notes or passwords with Mi Account, the data can be stored there. It's a separate storage facility not directly linked to Google.
To check and clear this data, go to Settings → Mi → Mi Cloud Account. You must select Sync or Storage Management. If there is a Password or Notes item on the list with sync enabled, you can disable it or delete it via the i.mi.com web interface.
The web version of the cloud provides more flexible management tools. Go to the site from your computer, log in and go to the Notes or Security section, where you can selectively remove saved access keys that may have entered the cloud through Xiaomi's system features.
- 🔒 Turn off password sync before selling your phone so new owners won’t get access to your data.
- ☁️ Regularly check the list of trusted devices in the Mi Cloud in case of unauthorized access.
- 🗑️ Full cleaning of Mi Cloud is required when you reset your account or switch to a phone of another brand.
Remember that once you delete data from the cloud, it will disappear on your device the next time you sync it, and this is an important aspect of digital hygiene that users often ignore.
💡
Before selling your device, be sure to complete a full Wipe Data reset via the Recovery menu, not just through settings to ensure that all encryption keys are removed.
How to Remove Your Save Wi-Fi Password on Xiaomi
Xiaomi smartphones automatically remember the keys to access wireless networks. If you change your router or password on the network, the old saving can interfere with the connection or be broadcast to other devices through the ecosystem.
To remove the old network, go to Settings → Wi-Fi. Click on the arrow or gear icon next to the network name (or select Network Management at the top of the screen if the current network is not active).
New versions of HyperOS have introduced Wi-Fi password synchronization between Xiaomi devices, and if you delete the network on your phone, it can also be removed on a tablet or laptop of the same brand, if the corresponding option is enabled in the Mi Account.
| Action. | Impact on the device | Impact on the cloud |
|---|---|---|
| Forget the net. | Removing the key from the current phone | Possible synchronization of removal |
| Resetting network settings | Remove all Wi-Fi and Bluetooth pairs | Does not affect cloud reserves |
| Changing the router password | Requires manual reconnection | Requires an update in the Manager |
| Removal of one network | Safely, does not affect other data | Synchronize with an account |
| Complete Wi-Fi reset | Returning the settings to factory | Local operation. |
| Changing the key | We need to re-enter | You need to update to Google/Mi Cloud |
If the delete button is inactive or the network is constantly returning, try resetting the network settings.This action will return the connection settings to the original state, but will not affect your personal photos or contacts.
☑️ Wi-Fi security check
Clearing data in the browser and applications
Many users are unaware that browsers and social networks can store passwords independently of the system manager. For example, the built-in Mi Browser browser or the installed Chrome, Yandex have their own databases.
To clear the stored data in your browser, open its settings, search for the Privacy or Security section, and select Passwords, where you can delete specific records or clear all data at once, a similar procedure is performed for applications that have built-in login memory.
In some cases, applications cache login data. If deleting the password from the system manager didn't help, try clearing the app's cache. To do this, go to Settings → Apps → All apps, select the one you want and click Clear Data.
⚠️ Attention: Clearing the application data will result in logging out of the account inside this application and removing local settings.
Pay special attention to banking and financial services applications, which often use their own secure storage, and password removal in such cases usually occurs through the security menu of the application itself or by reinstallation.
What to do if the password is not deleted?
Resetting and complete deletion of data
If your goal is to prepare the phone for sale or transfer to another person, pinpoint password removal is not enough, you need to completely reset the device to factory settings, and this is the only way to ensure that biometrics and encryption keys are not restored.
Before the procedure, make sure to back up important data, as everything will be destroyed. Go to Settings → About Phone → Reset. Select “Erase all data.” The system will warn you of the consequences and require you to enter a password to unlock the screen.
Once reset, the phone will start as new. When it first turns on, it will request the Google account that was the main one on the device before the reset (FRP protection), a security mechanism that prevents the use of stolen phones.
- 📱 Make sure the battery is more than 50% before starting the reset.
- 🔓 Remember the password from your main Google account, otherwise your phone will be blocked.
- 📡 Turn off the internet before resetting if you forget your account password (this can help bypass the account). FRP in some cases, but not guaranteed).
The deletion process takes a few minutes, and don't interrupt it or turn off the phone until the language-selected welcome screen appears.
