What Is Wi-Fi Security Type and Why It Matters

A Wi-Fi security type is the encryption and authentication standard that a wireless router uses to protect data traveling between your device and the access point. When a network is secured, the information you send—passwords, messages, credit card numbers—is scrambled so that outsiders cannot read it easily. When a network is unsecured, that data travels in plain text and can be intercepted by anyone within range.

Understanding the security type matters for several reasons:

  • Data privacy: Encrypted networks protect your personal information from eavesdroppers.
  • Network safety: Some older security types are easily cracked, making them unsafe for sensitive logins.
  • Troubleshooting: If a device cannot connect, knowing the security type helps you match the right password and settings.
  • Smart shopping: When buying a new router or access point, you will know which modern standards to look for.

If you are trying to figure out How to Find Security Type for Wifi?, the first step is understanding what the different labels actually mean.

Common Wi-Fi Security Types Explained

Wireless security has evolved significantly over the past two decades. Here are the most common security types you will encounter when scanning network info.

Open or None

An open network uses no encryption at all. Anyone within range can connect without a password. These are common in coffee shops, airports, and hotels. While convenient, open networks expose your traffic to anyone running basic packet-sniffing software. Avoid entering passwords or financial details on open Wi-Fi unless you are using a trusted VPN.

WEP (Wired Equivalent Privacy)

WEP was the original Wi-Fi security standard. It is now considered obsolete and insecure. Modern tools can crack WEP keys in minutes. If you see WEP on a network you control, upgrade the router or replace it immediately. Never use WEP for home or business networks.

WPA (Wi-Fi Protected Access)

WPA was introduced as a temporary replacement for WEP. It uses TKIP encryption and was better than WEP, but it still has known vulnerabilities. WPA is rarely used today, though some legacy devices may still support it.

WPA2 (Wi-Fi Protected Access 2)

WPA2 has been the industry standard for many years. It uses AES encryption, which is strong and reliable when paired with a good password. Most routers and devices support WPA2. Look for “WPA2-Personal” or “WPA2-PSK” for home networks, and “WPA2-Enterprise” for business environments with a RADIUS server.

WPA3 (Wi-Fi Protected Access 3)

WPA3 is the newest generation of Wi-Fi security. It offers stronger protection against brute-force attacks, simpler setup for devices without screens, and improved encryption for open networks. If your router and devices support WPA3, it is the best choice for security.

WPA2/WPA3 Transition Mode

Many modern routers offer a mixed mode that supports both WPA2 and WPA3. This allows older devices to connect while still giving newer devices the benefit of WPA3. It is a good middle ground during the transition period.

Wi-Fi Security Types Comparison Table

The table below summarizes the key differences between the most common security types you will find when you scan network info.

Security Type Encryption Strength Common Use Recommendation
Open / None None None Public hotspots Avoid for sensitive tasks
WEP RC4 Very weak Legacy hardware Do not use
WPA TKIP Weak Older devices Avoid if possible
WPA2-Personal AES Strong Home and small office Good minimum standard
WPA2-Enterprise AES Strong Business with RADIUS Best for organizations
WPA3-Personal AES / SAE Very strong Modern home networks Best choice when available
WPA3-Enterprise AES / Suite B Very strong High-security business Best for enterprise

How to Find Security Type for Wifi? on Windows

Windows offers several ways to check the security type of a wireless network. The method you choose depends on whether you are already connected or just scanning nearby networks.

Using Windows Settings

  1. Click the Start button and open Settings.
  2. Go to Network & internet and then select Wi-Fi.
  3. Click on Hardware properties for the network you are connected to.
  4. Look under the Security type field. It will display something like WPA2-Personal or WPA3-Personal.

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. Select the Security tab. The security type and encryption type are listed there.

Using Command Prompt

If you prefer the command line, you can see detailed network info including security types for all visible networks.

  1. Open Command Prompt or PowerShell as Administrator.
  2. Type the following command and press Enter:
netsh wlan show networks mode=bssid
  1. Look through the output for the SSID you want. Each network entry includes an Authentication line that reveals the security type.

This command is especially useful when you want to scan network info without connecting to each network individually.

How to Find Security Type for Wifi? on macOS

Apple makes it relatively easy to check Wi-Fi security, especially if you already know where to look.

Using the Menu Bar

  1. Hold down the Option key on your keyboard.
  2. Click the Wi-Fi icon in the top-right menu bar while still holding Option.
  3. A dropdown menu appears showing details for your current network, including the security type (for example, WPA2 Personal).

Using System Settings

  1. Open System Settings (or System Preferences on older macOS versions).
  2. Go to Network and select Wi-Fi.
  3. Click Details next to the network you are connected to.
  4. Look for the security protocol listed under the network information.

Using Wireless Diagnostics

For deeper network info, macOS includes Wireless Diagnostics.

  1. Hold Option and click the Wi-Fi icon.
  2. Select Open Wireless Diagnostics.
  3. Ignore the assistant window and open the Window menu, then choose Scan.
  4. The scan window lists nearby networks and their security types.

How to Find Security Type for Wifi? on Android

Android interfaces vary by manufacturer—Samsung, Pixel, Motorola, and others place settings in slightly different spots—but the general process is similar.

  1. Open the Settings app.
  2. Tap Network & internet or Connections, then select Internet or Wi-Fi.
  3. Tap the gear icon next to the network you are connected to.
  4. Look for a field labeled Security, Security type, or Encryption. It may say WPA/WPA2 PSK, WPA2-PSK, or similar.

If you are trying to check a network you are not connected to, Android does not always show security details in the standard Settings app. In that case, you may need a third-party Wi-Fi analyzer app from the Play Store, or you can log into the router if you own the network.

How to Find Security Type for Wifi? on iPhone and iPad

iOS is more limited than Android when it comes to displaying security details directly in the Settings app.

  1. Open Settings and tap Wi-Fi.
  2. Tap the blue (i) icon next to the network you are connected to.
  3. Review the details screen. iOS often shows the router IP address and connection type, but it may not explicitly list WPA2 or WPA3 in the user interface.

If the security type is not visible on your iPhone, you can check the same network from a Windows PC or Mac, or log into the router administration page using the router’s IP address shown in the Wi-Fi details.

How to Find Security Type for Wifi? on Linux

Linux users have powerful command-line tools for checking Wi-Fi security and scanning network info.

Using nmcli

  1. Open a terminal.
  2. Run the following command to see available networks:
nmcli device wifi list
  1. Look at the SECURITY column. It may show WPA2, WPA3, or -- for open networks.

Using iwlist

  1. Run a scan with root privileges:
sudo iwlist wlan0 scan
  1. Replace wlan0 with your actual wireless interface name if different.
  2. Search the output for lines containing IE: IEEE 802.11i/WPA2 or WPA3 to identify the security type.

Using the Desktop GUI

On GNOME, KDE, or other desktop environments, open Settings, go to Wi-Fi, and click the gear icon next to the connected network. Security information is usually listed under the connection details.

How to Find Security Type for Wifi? Using Your Router Admin Page

If you own the network or have administrative access, the router’s web interface is the most authoritative source for security settings.

  1. Connect a computer or phone to the router via Wi-Fi or Ethernet.
  2. Open a web browser and enter the router’s IP address. Common addresses include 192.168.1.1, 192.168.0.1, or 10.0.0.1.
  3. Log in with the administrator username and password. If you never changed these, they may be printed on a sticker on the router.
  4. Navigate to the Wireless, Wi-Fi Settings, or Security section.
  5. Look for Security Mode, Network Authentication, or Encryption. It will specify WPA2-PSK, WPA3-SAE, WEP, or similar.

This method is also the best place to change your security type if you discover you are still using an outdated standard like WEP.

How to Find Security Type for Wifi? Using Command-Line Tools

Power users and IT professionals often prefer terminal commands because they are fast and scriptable.

Windows netsh

netsh wlan show interfaces

This shows security details for the currently connected interface.

macOS system_profiler

system_profiler SPAirPortDataType

This outputs detailed AirPort/Wi-Fi information, including authentication protocols.

Linux iw

iw dev wlan0 link

Use this to inspect the current connection, including the security cipher.

Third-party tools such as Wi-Fi analyzers can also scan network info and display security types graphically, but the built-in commands above are usually sufficient for most users.

How to Scan Network Info and Identify Security Type

Scanning network info means discovering the wireless networks within range and reading their broadcast details. When you scan, you typically see the SSID (network name), signal strength, channel, MAC address (BSSID), and security type.

Here is how to approach scanning safely:

  1. Use built-in tools first: The commands and settings described earlier are enough for most situations.
  2. Use Wi-Fi analyzer apps carefully: If you install a third-party scanner, check its permissions and privacy policy. Only scan networks you own or have explicit permission to analyze.
  3. Interpret the results: A network labeled “None” or “Open” has no encryption. WPA2 and WPA3 indicate encryption is active. WEP indicates outdated security.
  4. Do not connect blindly: Just because a network shows strong security does not mean it is legitimate. Attackers can create fake access points with familiar names. Always verify the SSID with the venue or network owner.

Scanning is a useful way to answer How to Find Security Type for Wifi? when you are evaluating multiple networks in an office building, apartment complex, or public space.

Tips and Best Practices for Wi-Fi Security

Knowing how to find security type is only half the battle. Applying that knowledge keeps your data safer.

  • Prefer WPA3 when available: If your router and devices support WPA3, enable it. If not, WPA2 with AES is still secure for most home users.
  • Avoid WEP and open networks for sensitive tasks: Do not shop online or access bank accounts on WEP or open Wi-Fi without a VPN.
  • Use strong, unique passwords: Even WPA3 can be undermined by a weak pre-shared key.
  • Create a guest network: Keep visitor devices isolated from your main network and smart home gadgets.
  • Disable WPS: Wi-Fi Protected Setup is convenient but has known security flaws.
  • Update router firmware: Manufacturers patch security vulnerabilities regularly.
  • Verify before connecting: If you are in a hotel or café, ask staff for the exact network name and security type instead of guessing.

Frequently Asked Questions

Why can’t I see the security type on my phone?

Some mobile operating systems hide technical details to keep the interface simple. iOS, in particular, does not always display WPA2 or WPA3 in the Wi-Fi settings screen. Try checking the network from a laptop or log into the router admin page instead.

Is WPA2 still safe to use?

Yes, WPA2 with AES encryption remains secure for most home and small business users, provided you use a strong password. WPA3 is newer and stronger, but WPA2 is not considered broken for everyday use.

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 type and password if required.

What does “Open” security mean?

An open network uses no encryption. Anyone can connect without a password, and data sent over the network is not protected from local eavesdropping.

Will my old devices work with WPA3?

Not necessarily. Older devices may only support WPA2 or WPA. If you enable WPA3-only mode, those devices may fail to connect. Use WPA2/WPA3 transition mode if you need to support both old and new devices.

Do hidden networks have better security?

No. Hiding the SSID does not encrypt traffic or stop determined attackers. The security type (WPA2, WPA3, etc.) is what actually protects your data.

How often should I check my Wi-Fi security type?

Check it when you set up a new router, after a firmware update, or if you suspect unauthorized access. Otherwise, once every few months is a good habit.

Can I trust public Wi-Fi security labels?

Public networks often show WPA2 or open, but you cannot verify who operates them. Treat all public Wi-Fi as untrusted and use a VPN for sensitive activity.

Conclusion

Learning How to Find Security Type for Wifi? is a practical skill that helps you protect your personal data, troubleshoot connection problems, and choose safer networks. Whether you are using Windows, macOS, Android, iPhone, Linux, or your router’s admin page, the methods in this guide give you a clear path to identifying WEP, WPA, WPA2, WPA3, or open networks.
