Introduction

Connecting a new device to a wireless network seems simple enough: select the network name, enter the password, and go. But sometimes you need to know more than just the password. You might need to confirm whether your network uses WPA2, WPA3, or an older standard before a smart home gadget will connect. You might be troubleshooting a connection issue on a laptop. Or you might be auditing your home network to make sure it is not running on outdated, vulnerable encryption.

That is exactly where the question How to Find Security Type of Wifi? comes in. Knowing your Wi-Fi security type tells you which encryption protocol is protecting your data, which devices are compatible with your network, and whether your connection meets modern security standards.

This guide walks you through every practical way to check your Wi-Fi security type. You will find step-by-step instructions for Windows, macOS, Android, iPhone and iPad, Linux, your router’s admin panel, and the command line. There is also a comparison table of common security types, troubleshooting tips, and a FAQ section to answer the most common questions.

What Is Wi-Fi Security and Why It Matters

Wi-Fi security refers to the set of protocols and encryption standards that protect data traveling between your device and your wireless router. When you connect to a secured network, your data is scrambled so that anyone intercepting the wireless signal cannot easily read it.

There are two main parts to Wi-Fi security:

  • Encryption: This protects the actual content of your data, such as passwords, emails, and credit card numbers, as it moves through the air.
  • Authentication: This ensures that only devices with the correct credentials can join the network.

Knowing your security type matters for several reasons. First, older devices may not support newer standards. If your router is set to WPA3-only, a smart bulb or older phone made in 2015 might not be able to connect at all. Second, some security types are fundamentally broken. WEP, for example, can be cracked in minutes with freely available tools. Third, if you are connecting to public Wi-Fi, knowing whether the network is open or secured helps you decide whether to use a VPN or avoid sensitive transactions.

When people ask How to Find Security Type of Wifi?, they are usually trying to solve one of these practical problems. The good news is that every major operating system makes this information available, even if it is sometimes hidden a few menus deep.

Common Wi-Fi Security Types Explained

Before diving into the how-to steps, it helps to understand the security types you are likely to encounter.

Open or None

An open network has no password and no encryption. Anyone within range can connect. You will often see these in coffee shops, airports, and hotels. While convenient, open networks expose your traffic to anyone else on the same network.

WEP

Wired Equivalent Privacy was the original Wi-Fi security standard. It is now considered obsolete and insecure. Attackers can crack WEP keys quickly using basic software. If your router still offers WEP, you should disable it immediately.

WPA

Wi-Fi Protected Access replaced WEP. It introduced TKIP encryption, which was better than WEP but still has known vulnerabilities. WPA is largely outdated today.

WPA2

WPA2 has been the dominant standard for well over a decade. It uses AES encryption and is considered secure when paired with a strong password. Most devices in the world still connect via WPA2.

WPA3

WPA3 is the newest generation. It offers stronger protection against brute-force attacks, simpler setup for devices without screens, and individualized encryption on open networks through Opportunistic Wireless Encryption. Not all devices support WPA3 yet, which is why many routers offer a WPA2/WPA3 transition mode.

WPA2/WPA3 Transition Mode

This mixed mode allows both WPA2 and WPA3 devices to connect to the same network. It is useful during the transition period but does not provide the full security benefits of a WPA3-only network.

How to Find Security Type of Wifi? On Windows

Windows offers several ways to check your Wi-Fi security type. The easiest methods use the graphical interface, but the command line works too if you prefer.

Method 1: Using Windows Settings

  1. Click the Start button and open Settings.
  2. Go to Network & internet and then select Wi-Fi.
  3. Click on the name of the network you are currently connected to.
  4. Scroll down to the Properties section.
  5. Look for the field labeled Security type. It will say something like WPA2-Personal AES or WPA3-Personal.

Method 2: Using Control Panel

  1. Open Control Panel and go to Network and Sharing Center.
  2. Click the name of your active Wi-Fi connection next to Connections.
  3. In the Wi-Fi Status window, click Wireless Properties.
  4. Open the Security tab.
  5. The Security type dropdown shows the encryption standard, such as WPA2-Personal.

Method 3: Using Command Prompt

  1. Press Win + R, type cmd, and press Enter.
  2. Type the following command and press Enter:
netsh wlan show interfaces
  1. Look for the lines labeled Authentication and Cipher. Together, these tell you the security type. For example, WPA2-Personal with CCMP means WPA2-AES.

If you are trying to answer How to Find Security Type of Wifi? on a work laptop, the Settings method is usually the fastest.

How to Find Security Type of Wifi? On macOS

Mac users have two convenient options: the menu bar shortcut and System Settings.

Method 1: Option-Click the Wi-Fi Icon

  1. Hold down the Option key on your keyboard.
  2. While holding Option, click the Wi-Fi icon in the top-right menu bar.
  3. Look at the name of your connected network in the dropdown list.
  4. Beneath the network name, macOS displays details including the security protocol, such as WPA2 Personal or WPA3 Personal.

Method 2: System Settings

  1. Open System Settings (or System Preferences on older macOS versions).
  2. Go to Network and select Wi-Fi.
  3. Click the Details button next to your connected network.
  4. Look for the Security field to see the protocol in use.

If you are connected to a network but cannot see the details, try disconnecting and reconnecting, or check the router admin panel instead.

How to Find Security Type of Wifi? On Android

Android devices vary by manufacturer—Samsung, Pixel, Motorola, and others customize the settings menu slightly—but the general path is similar.

General Steps

  1. Open Settings.
  2. Tap Network & internet or Connections, depending on your version.
  3. Select Internet or Wi-Fi.
  4. Find the network you are connected to and tap the gear icon beside it.
  5. Look for a field labeled Security, Security type, or Encryption.

On Samsung devices, the path is typically Settings > Connections > Wi-Fi > gear icon next to network. On Pixel devices, it is usually under Settings > Network & internet > Internet > gear icon.

Keep in mind that some Android versions only show security details for the network you are actively connected to. Saved networks that are not in range may not display this information.

How to Find Security Type of Wifi? On iPhone and iPad

Apple does not make this as straightforward on iOS as it does on macOS. If you open Settings > Wi-Fi and tap the information icon next to your network, you can see the IP address, router address, and DNS settings, but iOS does not display the Wi-Fi security type directly.

To find the security type on an iPhone or iPad, you have a few workarounds:

  • Use a Mac on the same network: If you have a MacBook connected to the same Wi-Fi, hold Option and click the Wi-Fi icon to see the security type.
  • Log into your router: Open a browser on your iPhone, enter your router’s IP address, and check the wireless settings page.
  • Use third-party apps with caution: Some apps on the App Store claim to show Wi-Fi security details, but be careful about granting network permissions to unknown developers.

iOS 16 and later allow you to view saved Wi-Fi passwords, but even that screen does not reveal the encryption standard. If you need to answer How to Find Security Type of Wifi? on an iPhone, the router admin panel is usually the most reliable method.

How to Find Security Type of Wifi? On Linux

Linux users can check Wi-Fi security through the desktop environment or the terminal. The exact steps depend on whether you are using GNOME, KDE, or another desktop.

Graphical Method (GNOME)

  1. Open Settings and go to Wi-Fi.
  2. Click the gear icon next to your connected network.
  3. Look for the Security tab or field.

Terminal Method

  1. Open a terminal window.
  2. If you use NetworkManager, run:
nmcli device wifi list
  1. Look at the SECURITY column in the output. It may show WPA2, WPA3, or — for open networks.

You can also query the active connection specifically: 

nmcli -f 802-11-wireless-security connection show "Your-SSID"

Replace Your-SSID with your actual network name. This command displays the key management and authentication settings in detail.

How to Find Security Type of Wifi? Via Router Admin Panel

If your device does not show the security type, or if you want to check settings for multiple networks at once, your router’s admin panel is the definitive source.

Step-by-Step

  1. Connect your computer or phone to the Wi-Fi network you want to inspect.
  2. Find your router’s IP address. Common defaults are 192.168.1.1, 192.168.0.1, or 192.168.100.1. On Windows, you can find it by running ipconfig and looking for the Default Gateway.
  3. Open a web browser and type the router’s IP address into the address bar.
  4. Log in with your administrator username and password. If you have never changed these, check the sticker on the bottom or back of the router.
  5. Navigate to the Wireless, Wi-Fi Settings, or Security section.
  6. Look for Security Mode, Encryption, or Authentication. It will display WPA2-PSK, WPA3-SAE, WEP, or similar.

The router panel is also where you can change the security type if needed. Just remember to save your changes and reconnect your devices afterward.

How to Find Security Type of Wifi? Using Command Line or Terminal

Advanced users and IT professionals often prefer command-line tools because they are fast and scriptable.

Windows Command Prompt

netsh wlan show interfaces

Check the Authentication and Cipher lines for details like WPA2-Personal and CCMP.

macOS Terminal

macOS includes an airport utility buried in the system frameworks. Run: 

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I

Look for link auth in the output, which shows the authentication protocol.

Linux Terminal

With NetworkManager: 

nmcli device wifi list

Or for a specific connection: 

nmcli -f 802-11-wireless-security connection show "SSID"

Command-line output is especially useful when you need to check the security type on a headless server or a remote machine over SSH.

Comparison Table: Wi-Fi Security Types

Use this table to quickly compare the most common security standards you will encounter when answering How to Find Security Type of Wifi?

Security Type Encryption Authentication Security Level Best For
Open / None None None None Guest access in trusted public spaces only
WEP RC4 Shared key Very weak Legacy devices only; otherwise avoid
WPA (TKIP) TKIP PSK or Enterprise Weak Older hardware that cannot do WPA2
WPA2 (AES) AES-CCMP PSK or Enterprise Strong Most home and business networks today
WPA3 AES-GCMP / SAE SAE or Enterprise Strongest Modern routers and devices
WPA2/WPA3 Transition AES PSK / SAE Moderate to strong Mixed environments with old and new devices

Tips and Best Practices for Wi-Fi Security

Finding your security type is only the first step. Once you know what you are working with, use these best practices to keep your network safe.

  • Use WPA3 if your router and devices support it. If not, WPA2 with AES is still secure for most home users.
  • Avoid WEP entirely. If your router only offers WEP, it is time to replace the router.
  • Create a strong, unique password. Avoid common words, birthdays, or simple patterns. A passphrase of three or four random words works well.
  • Change default router credentials. Many routers ship with admin/admin or admin/password. Change these immediately.
  • Set up a guest network. Give visitors internet access without letting them see your local devices.
  • Disable WPS. Wi-Fi Protected Setup is convenient but has known security flaws.
  • Keep router firmware updated. Manufacturers release patches for security vulnerabilities regularly.
  • Turn off remote administration unless you absolutely need it.

If you run a business, consider WPA2-Enterprise or WPA3-Enterprise with a RADIUS server so that each user has individual login credentials instead of a shared pre-shared key.

Troubleshooting: What If You Cannot Find the Security Type?

Sometimes the security type is not where you expect it. Here are common scenarios and how to handle them.

iPhone or iPad Does Not Show It

As mentioned earlier, iOS does not display the security type in the Wi-Fi settings menu. Use a Mac on the same network or log into the router admin panel from your phone’s browser.

Router Admin Panel Is Locked

If you do not know the router login credentials, check the label on the device. If someone changed them and you do not have the new password, you may need to reset the router to factory defaults. Be aware that this will erase custom settings, including your Wi-Fi name and password.

Hidden Network

If the network does not broadcast its SSID, some devices may not show full security details until you manually connect. Once connected, the usual methods should work.

Managed or Work Device

On a corporate laptop, IT policies may hide certain network details. Contact your help desk if you need to know the security type for compatibility reasons.

Frequently Asked Questions

Can I change my Wi-Fi security type?

Yes. Log into your router’s admin panel, go to the wireless security settings, and select a different mode. Save the changes, and reconnect your devices using the new security settings.

Is WPA3 backward compatible with WPA2 devices?

Pure WPA3 mode is not backward compatible with older WPA2-only devices. However, most modern routers offer a WPA2/WPA3 transition mode that allows both types of devices to connect.

What does WPA2-PSK mean?

WPA2-PSK stands for Wi-Fi Protected Access 2 – Pre-Shared Key. It means the network uses a single password shared by all users, which is typical for home networks. WPA2-Enterprise uses individual usernames and passwords and is common in businesses.

Can I see the security type for a network I am not connected to?

On most operating systems, you can see the security type of nearby networks when scanning, but detailed information is usually only available for the network you are actively connected to. Your router admin panel shows security settings for all networks it broadcasts.

Is public Wi-Fi safe?

Open public Wi-Fi is not encrypted, so avoid logging into bank accounts or entering sensitive data without a VPN. Even networks with a captive portal login may not encrypt your traffic after you connect.

How often should I change my Wi-Fi password?

There is no strict rule, but changing it once or twice a year is a good habit. Change it immediately if you suspect someone unauthorized has joined your network.

Does hiding my SSID improve security?

Not significantly. Hidden networks can still be discovered with basic tools, and hiding the SSID can cause connection issues for some devices. Strong encryption and a good password matter much more.

Conclusion

Knowing How to Find Security Type of Wifi? is a practical skill that helps you troubleshoot connection problems, choose compatible devices, and keep your data safe. Whether you are using Windows, macOS, Android, iPhone, Linux, or your router’s admin panel, the information is available if you know where to look.

Start with the built-in settings on your device. If those do not show what you need, the router admin panel is the most reliable fallback. Once you know your security type, make sure you are using WPA2 or WPA3 with a strong password, and avoid outdated standards like WEP whenever possible.

By following the steps in this guide, you can quickly check your Wi-Fi security type and make informed decisions about your network configuration. Stay secure, and enjoy a reliable wireless connection.
