Many users encounter a situation where their smartphone refuses to connect to a known network or requires re-entering their credentials. This often happens after a router upgrade, a software update, or a change in the access point's security key. At this point, the device owner faces the challenge of removing the phone's Wi-Fi password so the device can reconnect to the internet or stop attempting to use incorrect credentials.
The process for deleting a saved access key depends on your device's operating system. On Android and iOS, the steps differ significantly due to different security architectures and user interfaces. Completely deleting a network profile — This is the most reliable way to force the phone to “forget” the old settings and request the current data during the next connection attempt.
In some cases, the problem isn't with the phone itself, but with the router's cache or an IP address conflict. Before resorting to drastic measures, it's worth trying to simply "forget" the network in the settings. This action forcibly disconnects the current connection and erases all saved settings for a specific access point from the device's memory, including the incorrect password.
Wireless connection management on modern smartphones has become more flexible, but sometimes hidden deep within menus. If you're seeing "Saved" or "Authentication Error" messages on your phone, it's time to clear that profile. Below, we'll detail the methods for different platforms and operating system versions.
Deleting a network profile on Android
In the Android operating system, the process of deleting a saved password is called "Forget Network." This action is available on most versions of the OS, starting with Android 10 and ending with the latest releases 14 and 15. However, the menu location may differ depending on the manufacturer's shell, whether it's MIUI, One UI or Stock Android.
To get started, open Settings and go to the Wi-Fi section. Find the network you want to remove in the list. The desired option is usually hidden next to the network name or in an expanded menu (often indicated by a gear or arrow). Tap it to see detailed connection information.
In the menu that opens, look for the "Delete" or "Forget" button. The system may ask for confirmation, warning that all network data will be erased. This is exactly what we need: full reset of parameters connection for this access point. After this, the phone will stop automatically trying to connect to this router.
⚠️ Note: If you are in range of a network and it is active, your phone may immediately prompt you for the password again when you tap the network name again. Please be prepared to enter the current passcode.
On some devices with custom shells, the path may look different. For example, in Xiaomi or Samsung Sometimes you need to long-press the network name in the general list to bring up the context menu with the delete option. If this doesn't work, try searching for the "More" or "Advanced Settings" section within the Wi-Fi menu.
It's important to understand that deleting a network doesn't affect other saved profiles. You can safely delete old or unnecessary connections without fear of losing access to your home or work internet, as long as their profiles remain intact. This also helps speed up the network search process, as the phone stops scanning the air for known but currently unavailable hotspots.
How to forget a network on iPhone and iPad
In the ecosystem Apple Wireless connection management is centralized and unified. To remove the Wi-Fi password on an iPhone, you need to follow a series of steps in the settings menu. The iOS interface has remained stable for many years, so these instructions are relevant for most current models, including iPhone 11, 12, 13, 14, and 15.
Open the Settings app and select "Wi-Fi." Make sure the wireless switch is turned on. In the list of available networks, find the one marked with a blue checkmark (currently connected) or listed under "My Networks" below. Tap the blue information icon. (i) to the right of the network name.
In the connection details menu that opens, you'll see the "Forget This Network" option at the very top. Tapping it will prompt you for confirmation. This prevents you from accidentally deleting important profiles. Once confirmed, your iPhone will immediately delete all saved data, including your password, proxy settings, and static IP address (if you set them manually).
- 📱 Open "Settings" from the home screen.
- 📡 Go to the "Wi-Fi" section.
- ℹ️ Click on the blue icon
(i)next to the desired network. - 🗑️ Select "Forget this network" and confirm the action.
If a network isn't currently connected but is listed as known, it may appear below, under the "My Networks" heading, or simply in the general list of available networks. The process for deleting a network is similar: click the information icon and choose to forget the network. This is especially useful if you've moved and the router has changed hands but retains the old name (SSID).
After completing these steps, your iPhone will no longer automatically connect to this hotspot. If you want to connect again, the device will ask for the password again, just like it did the first time. This ensures that old, possibly modified, data doesn't interfere with establishing a new connection.
Resetting network settings: a radical method
Sometimes deleting a single profile doesn't solve the problem, especially if the system has accumulated software errors or configuration file conflicts. In such cases, experts recommend reset network settingsThis operation resets all connection settings to factory defaults, deleting all saved Wi-Fi networks, Bluetooth settings, and cellular settings.
On Android, this feature is usually accessed through the "System" or "General Settings" menu. Look for the "Reset settings" or "Backup and reset" option. It's important not to confuse this with a full factory reset, which deletes all personal data, photos, and apps. We're only interested in resetting network settings.
On iPhone, this feature is located along the path Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsThe device will warn you of the consequences: all Wi-Fi passwords will be deleted, cellular settings will be reset to default, and Bluetooth device names will be forgotten. Personal files and apps will remain intact.
⚠️ Important: Before resetting your network settings, make sure you know the passwords for important Wi-Fi networks, as it will be impossible to restore them from your phone's memory after this procedure.
This method often helps resolve issues where the phone "sees" the network but can't connect, or when the IP address acquisition error persists. After rebooting, the device will have a clean network configuration, eliminating any software conflicts.
☑️ Ready for network reset
It's worth noting that after resetting your network settings, your phone may behave as if it were new in terms of connections: it will begin offering available networks and requesting permission to connect to neighboring hotspots. This is normal behavior and indicates that old "hangovers" in the system have been successfully removed.
Connection problems and authentication errors
Even after removing the password and re-entering it, users may encounter the message "Authentication Error" or "Failed to Connect." This indicates that the issue may not be with the phone, but rather with inconsistent security settings or router configuration. In such cases, simply deleting the profile doesn't help; a deeper analysis is required.
One common cause is the wrong encryption type. Modern routers often use the standard WPA3, while older phones can only support WPA2If you've removed the password and re-entered it, but the error persists, try changing the security type in your router settings to mixed mode. WPA2/WPA3 or temporarily disable WPA3.
It's also worth paying attention to the MAC filtering feature. If MAC address filtering is enabled on the router, even the correct password will prevent the phone from connecting unless its unique identifier is whitelisted. Removing the password on the phone is pointless; you need to add the device's address to the router settings.
The table below lists the main causes of connection errors and how to resolve them:
| Error type | Possible cause | Solution method |
|---|---|---|
| Authentication error | Incorrect password or encryption type | Remove the password, check the keyboard layout, and change WPA3 to WPA2. |
| Obtaining IP address... | DHCP conflict or pool overflow | Reboot your router and set a static IP on your phone. |
| Saved, no access | Problems with the provider's Internet channel | Check connection status on other devices |
| Access denied | MAC filtering is enabled on the router. | Add the phone's MAC address to the allowed addresses on the router. |
If none of these methods help, the problem may lie with the phone's Wi-Fi module drivers. In this case, updating the device's firmware or, in extreme cases, a full factory reset with the erasure of all data may help.
Using a QR code for quick connection
Modern smartphones not only allow you to capture passwords but also easily share them, eliminating the need for manual entry. If you need to connect your phone to a network for which you don't remember the password or don't want to enter it manually, use a QR code.
On Android 10 and above, as well as iOS 11+, you can generate a QR code for your current network. If you have another phone already connected to Wi-Fi, you can share its screen with the new device. The new phone's camera will recognize the code and offer to connect without entering a password.
To do this, go to Wi-Fi settings on a device with network access and tap the gear icon or the share icon. A QR code will appear on the screen. Point the other phone's camera at it. This is a convenient way to avoid having to take a picture and re-enter the password if you simply want to add a new device.
What to do if the QR code cannot be read?
Make sure the screen is bright enough, the camera is 10-15 cm away, and the lens is clean. Also, check that QR code scanning is enabled in the camera app.
This method is especially useful in offices or cafes, where administrators post QR codes on the walls. Scanning such a code automatically retrieves the current network settings, including the encryption type and password, eliminating the need for human error.
Router settings: when intervention is needed
In some cases, to remove a password on your phone, you first need to change the router settings. For example, if you forgot your network password and can't connect any devices, you'll need to access the router's web interface.
Connect to the router via a LAN cable or from a computer that already has network access. Enter the router's IP address (usually 192.168.0.1 or 192.168.1.1) in the browser. In the Wireless section, you can change the password (Pre-Shared Key) to a simpler one or disable encryption entirely (not recommended) for a temporary connection on your phone.
You can also check the number of connected clients here. If the device limit is reached, a new phone will not be able to connect, even if the password is correct. In this case, you need to remove unknown devices from the client list or expand the DHCP address pool.
⚠️ Note: Changing router settings (encryption type, channel, channel width) may require re-entering the password or reconnecting all devices in your home. Please do this consciously.
Please remember that after changing the router's security settings, you will need to "forget" the network and enter a new password on all your phones and tablets. This is a standard security procedure to prevent unauthorized access with outdated keys.
Regularly checking the list of connected devices on your router helps identify "neighbors" who may have cracked your password. If you discover an unknown device, immediately change the router password and reset the password on all your trusted phones.
Frequently Asked Questions (FAQ)
Is it possible to view the saved Wi-Fi password on my phone?
On Android 10 and higher, as well as iOS 16+, this is possible. In the Wi-Fi settings, next to the saved network, there's often a "Show Password" button or the option to generate a QR code with the password written in plain text. On older versions of Android, root access is required.
What happens if I forget the network but don't know the new password?
Your phone will simply stop connecting to the hotspot automatically. You won't lose any data on your phone, but your Wi-Fi connection won't work until you find the network owner or remember the access key.
Why does the phone say "Saved" but won't connect?
This means the phone has remembered the network and password, but can't authenticate. This could be due to the password being changed on the router, a weak signal, or the router blocking the device. Deleting the network ("Forget") and re-entering it may help.
Does removing the password affect internet speed?
Deleting a profile itself doesn't affect speed. However, if the phone has been unable to connect for a long time due to an error and has been constantly trying to reconnect, then a successful reconnection may improve connection stability.
Do I need to restart my phone after deleting a network?
This isn't usually necessary. The system applies the changes immediately. However, if you're experiencing glitches or problems discovering other networks, a reboot will help clear the network stack and update the drivers.
