What Is a Wi-Fi Security Type?

A Wi-Fi security type is the encryption and authentication protocol that a wireless network uses to protect data transmitted between devices and the access point. When you connect to a Wi-Fi network, your device and the router perform a handshake that establishes which protocol will be used. The most common protocols you will encounter include WEP, WPA, WPA2, and WPA3, each with different strengths and weaknesses.

The security type is configured on the router side, but your device must support it in order to connect. If your device only supports older protocols and your router is set to a newer one, the connection will fail. This is why knowing how to find the security type for Wi-Fi is so valuable when diagnosing connectivity problems.

In addition to the protocol itself, security types also define the cipher used for encryption. Common ciphers include TKIP and AES. AES is considered much more secure and is the standard for modern networks. TKIP was introduced as a temporary fix for WEP vulnerabilities and is now deprecated.

Why Identifying Your Security Type Matters

There are several practical reasons why you should know your Wi-Fi security type. First, security. If your network is still using WEP or WPA with TKIP, it is vulnerable to attacks that can crack the password in minutes. Knowing your security type lets you take corrective action before a breach occurs.

Second, compatibility. Older devices such as legacy printers, IoT gadgets, and older smartphones may not support WPA3 or even WPA2. If you recently upgraded your router and devices stopped connecting, the security type is often the culprit.

Third, performance. Some older security protocols limit throughput. WPA2 with AES generally allows full speeds, while TKIP-based connections may cap at 54 Mbps. If you are not getting the speeds you pay for, checking the security type is a smart move.

Finally, compliance. Businesses and organizations often have policies requiring specific security standards. Knowing how to find the security type for Wi-Fi helps IT administrators verify that networks meet those requirements.

Common Wi-Fi Security Types Explained

Understanding the different security types helps you interpret what you find when checking your network. Here is a breakdown of the most common ones.

WEP (Wired Equivalent Privacy)

WEP was the original Wi-Fi security standard introduced in 1997. It uses a static key and RC4 encryption, but its implementation has severe flaws. Today, WEP can be cracked in minutes using freely available tools. It should never be used on a modern network.

WPA (Wi-Fi Protected Access)

WPA was introduced as an interim replacement for WEP. It uses TKIP for encryption and dynamic keys, making it more secure than WEP. However, TKIP has its own vulnerabilities and WPA is now considered outdated.

WPA2 (Wi-Fi Protected Access 2)

WPA2 became the standard in 2004 and uses AES encryption. It is still widely used and is considered secure when configured with a strong password. WPA2-Personal uses a pre-shared key, while WPA2-Enterprise uses 802.1X authentication with a RADIUS server.

WPA3 (Wi-Fi Protected Access 3)

WPA3 is the latest standard, introduced in 2018. It offers stronger encryption, protection against offline dictionary attacks, and forward secrecy. WPA3-Personal uses Simultaneous Authentication of Equals (SAE), which is more resistant to brute-force attacks. WPA3-Enterprise provides 192-bit security for high-security environments.

Open Networks

An open network has no security at all. Anyone can connect and intercept traffic. These are common in public spaces but should never be used for sensitive communications without a VPN.

How to Find the Security Type on iPhone and iPad

iOS does not display the security type in a simple settings screen, but there are still ways to find it.

Using the Shortcuts App

  1. Open the Shortcuts app.
  2. Create a new shortcut and add the action Get Network Details.
  3. Run the shortcut to display information including the security type.

Checking via Router

Since iOS limits direct access to network details, the most reliable method is to log into your router’s admin panel and check the wireless security settings there. This is often the most accurate approach for iPhone users.

How to Find the Security Type on Linux

Linux users have several command-line tools available to inspect Wi-Fi security.

Using nmcli

Open a terminal and run:

nmcli device wifi list

The output includes a SECURITY column showing values like WPA1 WPA2, WPA2, or WPA3. This is one of the cleanest ways to find the security type on Linux.

Using iw

Run the following command to see detailed information about your wireless interface:

iw dev wlan0 info

Replace wlan0 with your actual interface name. For scanning nearby networks with security details, use:

sudo iw dev wlan0 scan | grep -i "rsn\|wpa\|security"

How to Find the Security Type on Your Router

Checking your router directly gives you the authoritative answer because the router is where the security type is configured.

Logging Into Your Router

  1. Find your router’s IP address, usually printed on a label or found by running ipconfig on Windows or ip route on Linux.
  2. Open a web browser and enter the IP address.
  3. Log in with your admin credentials.
  4. Navigate to Wireless Settings, Wi-Fi Settings, or Security.
  5. Look for a field labeled Security Mode, Authentication, or Encryption.

Common values you will see include WPA2-PSK (AES), WPA3-Personal, or Mixed Mode WPA2/WPA3. This is the definitive way to learn how to find the security type for Wi-Fi on your home network.

Using the Router App

Many modern routers come with companion apps. Open the app, go to the network or Wi-Fi section, and look for security settings. This is often easier than using the web interface.

Using Command Line Tools

Command line tools are invaluable for IT professionals and power users. They provide fast, scriptable access to network information without navigating through menus.

Windows Command Prompt

netsh wlan show networks mode=bssid

This command lists all visible networks along with their authentication and encryption types. It is especially useful when you want to compare the security of multiple nearby networks.

macOS Terminal

Use the airport utility as shown earlier, or try:

networksetup -getairportnetwork en0

This returns the name of your current network. Combine it with the airport command for full security details.

Linux nmcli

For a specific connection, use:

nmcli connection show "YourNetworkName" | grep -i security

This filters the connection details to show only security-related fields.

Troubleshooting Connection Issues

If you are having trouble connecting to a Wi-Fi network, the security type is often the reason. Here are common scenarios and how to resolve them.

Device Incompatibility

If an older device cannot connect to a WPA3-only network, check whether your router supports a mixed mode that allows both WPA2 and WPA3. This lets newer devices use WPA3 while older ones fall back to WPA2.

Wrong Password vs Wrong Security Type

Sometimes a connection failure is blamed on an incorrect password when the real issue is a mismatched security type. If you are sure the password is correct, verify that your device supports the router’s security protocol.

Hidden Networks

Hidden networks do not broadcast their SSID, but they still use a security type. When manually connecting, you must select the correct security type from a dropdown. Choosing the wrong one will cause the connection to fail.

Tips and Best Practices

Here are some practical tips to keep your Wi-Fi secure and your devices connected smoothly.

  • Use WPA3 if possible. It provides the strongest protection available for consumer networks.
  • Fall back to WPA2-AES if needed. If you have older devices, WPA2 with AES is still secure and widely compatible.
  • Avoid TKIP. If your router offers a TKIP option, disable it. TKIP is deprecated and limits performance.
  • Never use WEP. If a device only supports WEP, consider replacing it.
  • Use a strong password. Even the best security type cannot protect a weak password.
  • Keep firmware updated. Router manufacturers release updates that patch security vulnerabilities.
  • Separate IoT devices. Put smart home devices on a separate network or VLAN to limit exposure.
  • Check periodically. Revisit your security settings after firmware updates, as they can sometimes reset.
