How to find out your Wi-Fi encryption type on Android

In today's digital world, wireless connection security is becoming a critical concern for every user. Many smartphone owners don't even consider the security protocol their home or office network uses until they encounter connection issues or data leaks. Knowing How to find out the Wi-Fi encryption type on Android, allows not only to diagnose compatibility issues with new devices, but also to assess the actual vulnerability of the transmitted information.

By default, the Android operating system hides detailed connection parameters in the standard interface, focusing on ease of use. However, with the necessary knowledge and tools, one can easily access the hidden technical details of protocols. WPA2, WPA3 or outdated WEPIn this article, we'll cover all available methods, from standard settings to using the command line.

Understanding the differences between encryption methods will help you find the optimal balance between speed and security. For example, older devices may not support the latest standards, requiring router reconfiguration. Let's look at where exactly this information is stored in the system and how to retrieve it without root access.

Why do you need to know the network security protocol?

The main reason a user might need to check the encryption type is hardware compatibility. Modern flagship smartphones often feature Wi-Fi 6 and 6E modules, which require the protocol. WPA3 to operate at maximum speed. If your router is configured in the default mode or an older version WPA/WPA2, the device may not reach its full potential or refuse to connect to the 5 GHz network at all.

Furthermore, knowing the current security status is essential for security audits. Many users still use default passwords or, worse, leave encrypted networks open. WEP, which can be cracked in minutes even by a novice. Checking the encryption type allows you to quickly identify weaknesses in your home network configuration and update your router settings to the latest standards.

⚠️ Warning: Using the outdated WEP or WPA (TKIP) protocol makes your network vulnerable to traffic interception even at distances of several hundred meters. If diagnostics reveal the presence of these standards, change your router settings immediately.

Information about the encryption type is also often required by system administrators when setting up corporate networks. In such cases, it is important to ensure that the client device supports the required authentication methods, such as 802.1x or EAP-TLS, which are often hidden deep in Android system logs.

Standard verification methods in Android settings

Starting with Android 10, Google significantly overhauled the Wi-Fi settings interface, making it more informative but sometimes confusing. In most cases, the standard settings menu is sufficient for obtaining basic security information. However, it's worth noting that the information displayed may vary depending on the manufacturer's skin (e.g., One UI from Samsung or MIUI from Xiaomi).

To start checking, open the application Settings and go to the section Wi-Fi or ConnectionsFind the network you're currently connected to or select one from the list of saved networks. Clicking the gear icon or arrow next to the network name will take you to the detailed information menu.

Here you should look for a field with the name Security (Security). This section will display the current protocol. Depending on your Android version, you may see the following values:

• 🔒 WPA3-Personal — the most modern and safe standard at the moment.
• 🔒 WPA2/WPA3-Personal - mixed mode for compatibility with older devices.
• 🔒 WPA2-PSK — the most common standard providing reliable protection.
• ⚠️ WEP or Open - critically outdated or missing protection methods.

In some cases, especially on stock Android (such as Pixel and Motorola), security information may be hidden under the "More" or "Advanced Settings" button. If you don't see the encryption type right away, try scrolling down or tapping the three dots in the corner of the menu.

⚠️ Note: Smartphone manufacturers' interfaces (Samsung, Xiaomi, Realme) may change with each firmware update. The location of the "Security" section may differ from the algorithm described above.

Using a QR code to obtain network data

One of the most elegant and quick ways to find out the encryption type, which was introduced in Android 10 and later, involves the QR code sharing feature. This method doesn't require root access and works on the vast majority of devices, as it's a system feature.

The method works by generating a QR code to connect another device, generating a string containing all the necessary network parameters, including the SSID, password, and, most importantly, the encryption type. To use this:

1. Open Settings → Wi-Fi.
2. Click on the gear next to the active network.
3. Select the button Share or QR code.
4. Complete biometric authentication (fingerprint or face).

Below the QR code image, a text string of the following format is often displayed: WIFI:T:WPA;S:MyNetwork;P:Password;;The letter after T: It just indicates the type of security. If it says WPA, WPA2 or WPA3 - this is the desired parameter.

What do the letters in the Wi-Fi line mean?

T:WPA — security type (WEP, WPA, WPA2, WPA3). S: — network name (SSID). P: — password. If the T field is empty (T:), then the network is open and does not require a password.

If the text string isn't displayed below the code, you can scan the QR code with any third-party scanner app or even another phone's camera. The app will decode the string and display its contents, where you can easily find the parameter. T (Type).

Viewing technical specifications via ADB

For advanced users who find standard methods insufficient, there is the option of obtaining detailed technical information via the Android debug bridge (Android Debug Bridge). This method requires connecting your smartphone to a computer and having ADB drivers installed. It allows you to see raw data that the interface hides from the average user.

To get started, you need to enable developer mode on your phone (by pressing the build number 7 times in About the phone) and activate the item USB debuggingAfter connecting to your PC, run the command to get a list of all saved networks and their settings:

adb shell cmd wifi get-network-detail [SSID]

However, a more universal way is to read system configs through the shell, if the device has the appropriate access rights, or use the utility wpa_cli Directly through the ADB shell. The command to launch the utility looks like this:

adb shell wpa_cli status

In the output of this command you need to look for the line pairwise_cipher or group_cipher. Values CCMP indicate the use of AES (the standard for WPA2/WPA3), and TKIP — to the outdated WPA. Also the line key_mgmt will show the key management method, for example, WPA2-PSK.

Specifics of different Android versions and shells

The fragmentation of the Android ecosystem means that the same question of "how to find out the encryption type" is answered differently across devices from different brands. Owners of stock Android smartphones (Google Pixel, Nokia, Motorola) typically have access to the most comprehensive data in the standard menu, as they follow Google's guidelines.

The situation with devices Samsung (One UI shell) often requires careful attention. In recent versions of One UI, security information may be hidden in the "Advanced" tab within the specific network menu. Sometimes, to display the encryption type, you need to click the "Change" button (pencil) in the password field, where the system will display the router's currently selected security protocol.

Users Xiaomi (MIUI/HyperOS) may encounter a situation where the encryption type is only displayed when attempting to manually add a new network. In this case, if you select "Add Network" and enter the name of your current network, the system may automatically select security settings, displaying available encryption types in the drop-down list.

• 📱 Android 10-11: Information is often hidden and requires a QR code or third-party apps.
• 📱 Android 12-13: Improved interface, security data available in the "Details" menu.
• 📱 Android 14+: Implementing stricter privacy policies can hide MAC addresses and some encryption details from regular applications.

If you can't find the item you're looking for, try searching within your phone's settings by entering the word "Security" or the name of your network.

Third-party Wi-Fi analysis apps

When built-in tools aren't enough, specialized apps from the Google Play Store come to the rescue. Tools like WiFi Analyzer, Fing or WiFi Man Ubiquiti's apps provide in-depth technical information about your wireless environment. However, due to Android security restrictions introduced in recent versions of the OS, the functionality of these apps may be limited.

Apps can display the encryption type in the list of available networks, even if you're not connected to them. This is useful for analyzing neighboring networks or checking your own router from different points in the room. They will show not only the type (WPA2, WPA3), but also the channel used, the bandwidth and the signal level.

⚠️ Warning: Many apps request excessive permissions (access to contacts, background geolocation). Carefully check permissions before installing, as data about your Wi-Fi networks may be sensitive.

Some apps require root access to display real passwords and full technical specifications of the active connection. Without root access, they often only show the information the OS is willing to provide through standard APIs. However, for a quick check of the encryption type (WPA against WEP) their capabilities are usually quite sufficient.

Frequently Asked Questions (FAQ)

Can the phone connect to the network if the encryption type is not supported?

No, connection will be impossible. If the router is configured for WPA3 only and your phone only supports WPA2, you will see the error "Unable to connect" or "Authentication error." Your phone must support the security protocol used by the router.

Does encryption type affect internet speed?

Yes, it does. Outdated encryption methods (WEP, WPA-TKIP) limit the maximum connection speed and prevent the use of modern Wi-Fi standards (n, ac, ax). For higher speeds, WPA2-AES or WPA3 is required.

Why does the settings say WPA2/WPA3, what does this mean?

This is compatibility mode. The router supports both protocols simultaneously. New devices will connect via secure WPA3, while older devices that don't support it will be able to connect via WPA2. This is the optimal setting for a mixed device fleet.

Is it dangerous to use open Wi-Fi without encryption?

Extremely dangerous. On open networks, all traffic is visible to anyone on the network. Attackers can intercept passwords, correspondence, and bank card information. Use a VPN when connecting to public Wi-Fi.

How do I change the encryption type on my phone?

You can't change the encryption type on your phone itself, as this is a router (access point) setting. The phone simply adapts to the network rules. To change the encryption type, you need to access the router settings (usually through a browser at 192.168.0.1 or 192.168.1.1) and change the security settings in the Wireless section.
