Changing your wireless network password is a basic but critical step to protecting your personal data from unauthorized access. Users macOS We often need to update access keys, especially after purchasing a new router or suspecting a hack. Apple's operating system provides several ways to manage saved network credentials, but the process isn't always intuitive for beginners.
Unlike mobile devices, where network management is limited to the current connection, Mac computers allow you to edit the connection history and passwords stored in the system vault. Change password This may be necessary not only for the router itself, but also to update the keychain entry if you've previously changed the router settings and the laptop continues to try to connect with the old settings. Understanding these mechanisms will help you avoid connection issues in the future.
In this article, we'll take a detailed look at how to change your Wi-Fi password on a Mac using standard system preferences and advanced utilities. We'll cover working with With a bunch of keys, where all your saved passwords are stored, and we'll touch on the command line for those who prefer the terminal. We'll also cover the security nuances of encryption protocols.
Preparing to change your password and checking your current settings
Before making any changes to the network configuration, ensure you have administrator rights on the device and know the current router password to access its web interface. If you simply want to update the saved password on your Mac after changing the router settings, you will need a new access key. If you need to change the access point password itself, ensure your computer is connected to the router via Ethernet cable or you are ready to reconnect via Wi-Fi after changing the settings.
⚠️ Attention: Changing the password in your router settings will disconnect all devices using that key. Make sure you have physical access to the router to reboot it if the connection is lost.
You can check your current connection status using the menu in the top bar of the screen. Click on the icon Wi-Fi, you'll see the connection status and network name. For more detailed information, including the IP address and subnet mask, you can go to the system settings section. This will help you determine whether you're using a static or dynamic IP, which can be important for manual configuration.
If you plan to change the router's security settings (for example, switching from WPA2 to WPA3), make sure all your devices support the new standard. Older devices may stop seeing or connecting to the network. In such cases, it's recommended to create a guest network with less stringent but separate security settings for compatibility.
Changing your Wi-Fi password through your router settings
The most common scenario is changing the password directly on the router. To do this, you'll need to open a browser and enter the device's IP address, which usually looks like this: 192.168.0.1 or 192.168.1.1The exact address is often indicated on a sticker on the bottom of the router. After entering the address, the system will ask for a username and password to access the control panel; by default, this is often admin/admin, if you haven't changed them before.
Once you're in the settings interface, find the section responsible for wireless networking. It may be called Wireless, Wi-Fi or Wireless network. Within this section, look for the subsection Security or SecurityThis is where you'll find the password change field (Network Key, Passphrase, Pre-Shared Key). Select the encryption type. WPA2-PSK (AES) or WPA3 for maximum protection.
- 🔐 Create a complex password consisting of at least 12 characters, including uppercase and lowercase letters and numbers.
- 📡 Change the network name (SSID) if you want it to be different from the manufacturer's default name.
- 💾 After applying the settings, be sure to click the "Save" or "Apply" button, otherwise the changes will not take effect.
After saving the settings, the router will restart the wireless module. Your Mac will lose the connection, and you'll need to enter a new password. macOS may prompt you to "Forget the Network" if a configuration conflict occurs, which is normal when security settings are changed.

Managing passwords with Keychain Access on macOS
The Mac operating system stores all saved Wi-Fi passwords in a special secure vault called Bunch of keys (Keychain Access). This tool not only allows you to view saved keys but also delete old entries, forcing the system to prompt you for the password again the next time you connect. This is especially useful if you've changed your router password and your Mac is still trying to connect with the old password.
To open the utility, click Command + Space to open Spotlight and type "Keychain Access." In the window that opens, select "Passwords" from the list on the left. Find the name of your Wi-Fi network in the center of the screen. Double-clicking on the network name will open the properties window, where you can check the "Show password" box.
To delete an old entry, which is often required when changing a password:
- Find the desired network in the list.
- Right click on it or press
Control + Click. - Select the "Delete" option.
After deleting the entry, macOS will prompt you for the password again when you try to connect to that network. This is an effective way to refresh cached data without having to reset your entire computer's network settings. Keychain is synced via iCloud, so changing or deleting the password may affect your other Apple devices.
What should I do if Keychain keeps asking for a password?
If the system constantly asks for a password to access Keychain, it's possible the user account login password has been changed, but the keys haven't been updated. Try logging into Keychain, selecting "Edit" → "Change Keychain Password," and entering the old password, then a new one that matches your current macOS login password.
Using Terminal to Manage Network Interfaces
For advanced users who prefer the command line, macOS provides powerful tools through TerminalThese tools not only allow you to view network information but also forcefully delete network profiles, which is sometimes more efficient than the graphical interface. To get started, open Terminal via Finder or Spotlight.
One useful command is to view all saved networks. However, in modern versions of macOS (especially on Apple Silicon chips), direct control via networksetup Requires administrator rights. To forget a network (remove it from the list of known networks), use the following command:
sudo networksetup -removenetwork"NetworkName" Wi-FiInstead of Wi-Fi the interface name can be used, for example, en0You can find out the exact name of the interface using the command networksetup -listallhardwareportsAfter executing the command, the network will be removed from the system preferences, and the next time you connect, you will need to re-enter the password.
⚠️ Attention: Commands in Terminal are executed instantly and without additional confirmation. Be careful when entering the network name to avoid accidentally deleting important system profiles or networks with similar names.
Wi-Fi Encryption Methods Comparison Chart
When setting a password, it's important to choose the right encryption method. This affects not only security but also connection speed. Below is a comparison of the main standards available in modern routers.
| Protocol | Security | Compatibility | Recommendation |
|---|---|---|---|
| WEP | Critically low | Obsolete devices | Do not use |
| WPA (TKIP) | Low | Old gadgets | Replace with WPA2 |
| WPA2 (AES) | High | Almost all devices | Recommended standard |
| WPA3 | Maximum | New devices (2018+) | Ideal for new networks |
Usage WPA2 (AES) is the gold standard today, providing a balance between compatibility and security. The protocol WPA3 Offers improved protection against brute-force attacks, but may not be supported by some smart home devices. If your router supports mixed mode (WPA2/WPA3), this is often the best choice.
Troubleshooting connection issues after changing your password
After changing the Wi-Fi password on a Mac or router, the device sometimes refuses to connect, displaying an "Incorrect Password" error or endlessly attempting to establish a connection. This is often due to macOS caching old configurations. The first step should always be a full restart of the computer, not just waking it from sleep.
If rebooting doesn't help, try creating a new user on your Mac and testing the connection under that account. This will help determine whether the issue lies in the system settings of a specific profile or in the global network settings. It's also worth checking that "Maximum Compatibility" mode isn't enabled on your router, which can limit speed and stability.
In some cases, resetting network settings can help. On macOS, this can be done by deleting the configuration files in the folder /Library/Preferences/SystemConfiguration/. Wi-Fi related files (eg. com.apple.airport.preferences.plist), you can move it to a backup folder on your desktop and reboot. The system will create new configuration files from scratch.
Frequently Asked Questions (FAQ)
Where can I find my Wi-Fi password if it's saved on my Mac?
You can find the password in the Keychain app. Find the network name, open its properties, and check the "Show password" box. The system will prompt you for an administrator password or Touch ID to display it.
Why can't my Mac see the network after changing the password?
The broadcast channel or security standard may have changed. Try forgetting the network in the Wi-Fi settings and then rediscovering it. Also, check if the network is hidden (SSID).
Is it possible to change a Wi-Fi password without accessing the router?
No, changing the network password requires access to the router's admin panel. On a Mac, you can only change the saved connection password, but this will not change the access point's security settings.
How to completely reset network settings on macOS?
A hard reset requires deleting the network configuration files in the system library or using Terminal to delete all profiles. This will return the network settings to factory defaults.
