Modern smartphones based on Android have a convenient function of automatically connecting to well-known networks, which eliminates the need for the user to enter a complex security key each time. However, over time, the list of saved access points can grow, including outdated or insecure connections that are no longer used. A logical question arises: how to remove the Wi-Fi password on Android if the device has stopped working correctly or you want to clear the connection history?
The procedure for deleting network data may be required in various situations: from a banal change of the access key on the router to the need to completely wipe the device before selling it. It is important to understand that deleting a network from the phone does not change the settings of the router itself, but only makes the smartphone “forget” a specific access point. In some cases, a more radical approach is required, including resetting network settings or even a hardware reset of the router itself.
In this guide, we will examine in detail all existing methods for managing saved networks. You will learn how to manually remove a specific access point through the settings menu, how to perform a global network reset, and what to do if access to the router is completely lost. We will also touch on security issues and explain why storing old connection profiles can pose a risk to your personal data.
Manually deleting a network through Android settings
The easiest and safest way to delete information about a specific Wi-Fi network is to use the built-in operating system settings menu. This method allows you to selectively remove only those profiles that you no longer need, without affecting the rest of the device settings. The interface may differ slightly depending on the version Android and the manufacturer's shell (for example, One UI from Samsung or MIUI from Xiaomi), but the logic of actions remains the same.
First, you need to go to the wireless connections section. Typically the path looks like this: open Settings, then select Connections or Network and Internet. Next, go to section Wi-Fi. Here you will see a list of available networks, as well as a section with already saved access points. In new versions of the system, this list may be hidden under the “Saved Networks” button or displayed at the bottom of the screen.
Find in the list the network for which you want to remove the password. Click on the network name or the gear icon next to it to open detailed information about the connection. In the menu that opens, find the button Delete or Forget. After clicking, the system will ask you to confirm the action. By agreeing, you will instantly delete the network profile along with the saved password from the phone’s memory.
If the “Delete” button is inactive, make sure that the phone is not currently connected to this network. First, turn off Wi-Fi or switch to mobile data.
After completing this procedure, the smartphone will no longer try to automatically connect to this access point, even if it is in range. If you want to use this network again in the future, you will have to enter the password again. This is a great way to clear your list of coffee chains, hotels, or public places that you no longer plan to visit.
Global network reset
Sometimes manually deleting each network individually takes too much time, especially if the device has been in use for years and has accumulated dozens of connection profiles. In such cases, it is advisable to perform a complete network reset. This operation will reset all Wi-Fi, Bluetooth, and cellular settings to factory defaults, while deleting all saved passwords.
It is important to note that this procedure does not affect your personal files, photos, contacts, or installed applications. It only affects communication modules. However, before starting the process, it is recommended to make sure that you remember passwords from important home and work networks, since it will be impossible to recover them from the phone’s memory after a reset without special tools.
☑️ Preparing for a network reset
To reset, go to main Settings devices. Find the System or General settingssection, then select Reset or Restore and reset. In the list of options, find the line Resetting Wi-Fi, mobile data and Bluetooth settings. The system will warn you about the consequences of this action. Confirm the operation by entering your screen unlock PIN or pattern.
After rebooting the communication modules, the list of saved networks will be completely cleared. Your phone will behave like it just left the factory in terms of network connections. This is an effective method for solving problems when the phone does not see the network, constantly loses connection, or cannot obtain an IP address due to conflicting settings.
Deleting data through the file manager (root access)
For advanced users with superuser rights (Root), it is possible to directly edit system files in which data about wireless networks is stored. This method allows you to remove the Wi-Fi password on Android even in cases where the standard interface does not work correctly or is blocked. However, using this method requires great caution.
Data about networks in the Android system is stored in a special configuration file located in a protected directory. To access it, you will need a file manager that supports root access, for example Root Explorer or Solid Explorer. The path to the file usually looks like /data/misc/wifi/wpa_supplicant.conf. This file contains a list of all networks with their SSID and passwords in clear text.
Opening the file in a text editor, you will see code blocks for each network. Each block begins with a line network={ and ends with a closing bracket }. Inside the block there are parameters ssid (network name) and psk (password). To delete a network, you need to select the entire block corresponding to the unnecessary access point and delete it.
⚠️ Attention: Incorrect editing of system files can lead to the Wi-Fi module not working or even to a boot loop. Before making changes, be sure to create a backup copy of the file!
After saving the changes, the file must be made readable by the system. Typically permissions should be set to 644 (owner - read/write, group and others - read only). After this, you need to restart the device for the changes to take effect. This method gives full control over password storage, but carries risks for system stability.
What to do if the wpa_supplicant.conf file is missing?
In some modern versions of Android, network data may be stored encrypted or in another location, for example, in a database WifiConfigStore.xml. Direct editing in such cases is impossible without specialized utilities.
Resetting the router settings to factory settings
If your goal is not just to remove the network from the phone, but to completely remove the password from the router itself (for example, you forgot the key and cannot connect from any device), then you will need a hard reset of the router. This procedure will return the device to factory settings, erasing all configurations, including the network name, administrator password and provider settings.
On the case of most routers, such as TP-Link, ASUS or Keenetic, there is a small button or hole labeled Reset or WPS/Reset. To activate the reset, you need to turn on the router to the network, find this hole and hold the button inside with a paperclip or needle. You need to hold the button for 10-15 seconds until the indicators on the case begin to flash simultaneously.
After releasing the button, the device will reboot. Now the Wi-Fi network will be broadcast with the factory name, which is indicated on the sticker on the bottom of the router. The password will also be reset to default (or security will be disabled, depending on the model). You will be able to connect to the network without entering a key, but to set up Internet access you will need to go to the web interface of the router.
| Action | Result for phone | Result for router | Required actions after |
|---|---|---|---|
| Forget network in the menu | Deleting a specific profile | Settings do not change | Reenter the password when connecting |
| Reset the network on Android | Delete all saved networks | Settings do not change | Configure Wi-Fi and Bluetooth again |
| Hard Reset of the router | Reconnection required | Full reset of all settings | Set up the Internet and a new password |
Remember that resetting the router will also delete the PPPoE settings, L2TP or static IP issued by your ISP. If you do not have an agreement with the provider at hand indicating this data, it is better to refrain from this procedure and try to restore access using other methods.
Restoring access via WPS
In situations when you want to connect to your network, but do not remember the password and do not want to completely reset the router, you can use technology WPS (Wi-Fi Protected Setup). This standard allows you to connect a device to the network without entering a security key, using either a button on the router or a PIN code.
Most modern routers are equipped with a physical WPS button. To connect your phone, activate this function on your router by pressing the corresponding button. Then on your smartphone, in the Wi-Fi menu, select the option to connect via WPS (often it is hidden in the additional menu or appears automatically when scanning). The devices will find each other and establish a secure connection.
After successful connection, the phone will automatically save a new network profile with the current password. Although you won't see the password itself as text right away, it will be saved on the system. On some devices, with superuser rights or through special QR code scanner applications, you can then view the saved key as a pattern lock or text.
⚠️ Warning: WPS technology has known security vulnerabilities. After connecting, it is recommended to disable the WPS function in the router settings to prevent unauthorized access to your network by intruders.
This method is a compromise solution: it allows you to restore access without losing provider settings that would occur with a full reset. However, it only works if the WPS feature has not been previously disabled by the manufacturer or the user for security reasons.
Using WPS is a quick way to restore your connection without knowing the password, but remember to disable this feature immediately after use to protect your network.
Security issues and access management
Removing passwords and management networks are not only a matter of convenience, but also an important component of digital hygiene. Old network profiles, especially open networks or those with outdated encryption protocols, can become an attack vector. Attackers can create access points with names that match your saved networks to trick your phone into connecting automatically and intercepting traffic.
Regularly clearing your list of saved networks reduces this risk. If you travel or visit public places frequently, the habit of removing temporary nets immediately after use is a good defense. In addition, this prevents situations where the phone tries to connect to a weak network instead of a stable mobile data, wasting battery power.
It is also worth paying attention to the “Random MAC Address” function, which appeared in modern versions Android. When connecting to new networks, the phone can replace its real physical address with a random one. This makes it difficult to track the device across different access points, but can cause problems with older routers that have MAC address filtering configured. In such cases, in the settings of a specific network, you need to select the “Use device MAC address” option.
For maximum security, use a password manager to store Wi-Fi keys, and do not rely only on the phone memory. This will make it easy to restore access when changing devices.
If you plan to sell or give away your smartphone, simply deleting networks is not enough. It is recommended to perform a full reset of the device to factory settings (Factory Reset). This ensures that new owners will not have access to your connection history, as well as other personal data that may have been saved in the application cache.
Frequently asked questions (FAQ)
Is it possible to find out the saved Wi-Fi password on Android without root access?
On versions of Android 10 and newer this can be done through the settings. Go to Wi-Fi settings, click on the gear next to the desired network and select the “Share” option or the QR code icon. The password is often displayed below the code in text form, or you can scan the code with another phone to see the data.
Will the password be deleted from my other devices if I forget the network on one phone?
No, deleting the network occurs locally only on the device where you performed this action. If your devices are synced through a Google account or manufacturer's ecosystem (such as Samsung Cloud), settings may sync, but in most cases each device keeps its own list of networks.
What if the Forget Network button is greyed out (grayed)?
This means that you are currently connected to that network. First, turn off Wi-Fi or connect to a different access point. Also check to see if device administrator features or work profiles are enabled, which may block changes to network settings.
Does deleting a network affect Internet speed in the future?
Removing a network itself does not affect speed. However, if the phone constantly tried to connect to a weak or overloaded network from the list of saved ones, deleting this profile can indirectly improve the stability of the connection by forcing the device to select a better signal.
How to delete all networks at once without resetting the settings?
With standard Android tools, mass deletion without resetting is impossible. You can use third-party applications from Google Play that require access rights to the settings, or use the methods with root access and editing system files described above.
