What is a network security key & how to find it?

A network security key is a type of digital password that grants access to Wi-Fi networks and protects data transmission between connected devices. Often referred to as a Wi-Fi password, the network security key ensures only authorized users and devices can connect to a network, safeguarding information from unauthorized interception or tampering.

In this guide, we’ll explore the types of network security keys, how to find and manage your network security key, and best practices for securing your Wi-Fi network.

Types of network security keys

Network security keys differ in their encryption strength, compatibility, and security level. The main types include Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and WPA2, and WPA3.

WEP

WEP was among the earliest protocols developed for network security. It uses RC4 encryption but has since been deemed insecure due to vulnerabilities that make it easy for attackers to bypass. While WEP may still be available in older networks, it’s best to avoid using it for modern security needs.

WPA and WPA2

Developed as an improvement over WEP, WPA introduced stronger encryption, and WPA2 solidified this with the Advanced Encryption Standard. WPA2 is widely compatible and secure and remains the standard for many networks.

WPA3

The latest security protocol, WPA3, builds on WPA2 with even stronger encryption methods, including individualized encryption for each device in a network. This makes WPA3 especially effective for public or shared networks, providing enhanced protections and minimizing security risks. Devices with WPA3 support also benefit from simpler, more secure connection methods using QR codes or NFC.

How to find the network security key

If you're connected to a network, you can view the saved key on your device.

1. How to find the network security key on Windows

Navigate to Settings > Network & Internet > Network and Sharing Center. Click your Wi-Fi network name, navigate to Wireless Properties > Security, and check Show characters to display your network security key.

2. How to find the network security key on macOS

Navigate to Finder > Go > Utilities > Keychain Access. Double-click your Wi-Fi network name, enter your credentials, and check Show password to view the network key.

3. How to find the network security key on iPhone

Currently, iPhones don’t allow users to directly view saved Wi-Fi passwords. However, you can retrieve them if your iPhone is synced with a Mac via iCloud. On your Mac, open Keychain Access, search for your Wi-Fi network, and check Show password (you may need to enter your Mac credentials).

4. How to find my network security key on Android

If your device is running Android 10 or newer, navigate to Settings > Connections > Wi-Fi. Select the connected Wi-Fi network and tap Share to generate a QR code. Scanning this code will reveal the network security key below it.

5. How to locate the network security key on the router

Most routers have a label with the default network security key, often labeled as the Wi-Fi password or WPA key. This key can be changed after setup for added security.

Best practices for managing network security keys

Securing a network starts with a strong, well-managed security key. Here are some best practices to follow:

Use a complex, unique key: Choose a key that combines letters, numbers, and symbols for maximum strength. Avoid simple patterns or easily guessed phrases to reduce the key's vulnerability to brute-force attacks.

Update the key regularly: Changing your network security key periodically minimizes the risk of unauthorized long-term access. For networks with guest access or frequent users (like employees or regular visitors), updating the key every few months is especially beneficial.

Upgrade to WPA3 where available: Check if your devices and routers support WPA3, which provides the highest level of security currently available. WPA3’s advanced encryption and compatibility improvements make it ideal for secure data transmission and are particularly beneficial for public and multi-device environments.

How to fix errors like "The network security key isn't correct. Please try again."

If you encounter issues with your network security key, such as a “network security key mismatch” error, try these troubleshooting steps:

1. Check for typos

Network security keys are case-sensitive, so even a minor error can prevent connection. Double-check each character before reentering it.

2. Ensure device compatibility

Older devices may not support WPA3 and could experience connectivity issues. In these cases, WPA2 is often a compatible alternative.

3. Update devices and router firmware

Regular updates for your routers and devices can prevent compatibility issues and improve network performance, especially when newer security protocols are involved. Open Device Manager, expand Network adapters, right-click your Wi-Fi adapter, select Update driver, and choose Search automatically for updated driver software.

4. Run the network troubleshooter

Navigate to Settings > Update & Security > Troubleshoot > Additional troubleshooters, select Internet Connections, and run the troubleshooter.

5. Reset your network settings

To reset your network settings, navigate to Settings > Network & Internet > Status, then scroll down and click Network reset. Be aware that this will erase all your saved networks and passwords.

6. Reset the Wi-Fi adapter via Command Prompt (Run as administrator)

Run Command Prompt as an administrator and type the following commands:

After executing these commands, restart your computer and try to reconnect to the Wi-Fi network.

How ManageEngine Log360 enhances network security

ManageEngine Log360 is a unified SIEM solution designed to strengthen network security and simplify IT compliance. This comprehensive platform combines log management and advanced threat intelligence with user and entity behavior analytics (UEBA), offering you a way to secure networks proactively. Here’s how Log360 can help:

1. Real-time threat detection

Log360 monitors user activity across your network in real time, identifying unauthorized access attempts, privilege misuse, and deviations from normal patterns with UEBA. This provides immediate alerts, enabling a rapid response to potential insider threats.

2. Event correlation for attack patterns

The correlation engine aggregates events from multiple sources, linking related activities to detect multistage attacks. This feature helps you isolate suspicious patterns across different access points, ensuring early detection and allowing for swift incident response.

3. Compliance and reporting

The solution automates compliance with regulations like the GDPR, HIPAA, the PCI DSS, and SOX. It generates preconfigured reports and custom alerts, making it easier to enforce access control policies and maintain an audit trail for regulatory review.

4. Forensic analysis

Log360’s indexed log archives support efficient forensic investigations. In the event of an incident, this feature helps you retrace steps to analyze security breaches and prevent similar ones, strengthening your network's overall resilience.

FAQ

Is a network security key the same as a Wi-Fi password?

Yes, a network security key and a Wi-Fi password usually mean the same thing. Both refer to the password needed to access a Wi-Fi network.

How do I change my network security key?

To change the key, log in to your router’s settings via a web browser, typically by entering the router’s IP address. After logging in, navigate to the Wi-Fi or security settings to change the network security key.

Why is my network security key not working?

This error can result from incorrect entry, incompatible devices, or outdated firmware on your router or connected devices. Verifying your entry's accuracy, checking device compatibility, and updating the firmware can resolve this issue.

How often should I update my network security key?

Updating the key every three to six months is a good practice, especially in networks with multiple users. Frequent updates help minimize unauthorized access and keep your network secure.
