How to find your Wi-Fi password using Termux: secure methods and limitations

Forgot your home Wi-Fi password, and there's no sticker with the connection details on your router? Or do you need to connect a new device, but access to the router's admin panel is restricted? In such cases, users often look for ways to retrieve the saved password directly from their Android device—and Termux becomes one of the first tools that comes to mind. However, it's important to understand: this process has strict technical and legal limitations.

In this article we will look at legal methods getting Wi-Fi password via Termux (including using root-right), alternative methods without hacking networks, and we'll also explain why most online hacks don't work on modern Android versions. You'll learn which commands actually work, and which are a waste of time or even illegal.

⚠️ Warning: All described actions are applicable only to networks to which you are already connected and have access rightsAttempting to hack someone else's network is punishable by law (Article 272 of the Russian Criminal Code - "Unauthorized access to computer information").

1. What is Termux and why is it chosen for working with Wi-Fi?

Termux — is a terminal emulator for Android with support for packages from repositories LinuxIt allows you to run commands, scripts, and utilities similar to those used on desktop OSes. In the context of Wi-Fi, its popularity is due to:

• 🔧 Possibility of installing tools like aircrack-ng, wpa_supplicant or iwconfig (if you have root).
• 📱 Work without a PC - everything is done directly on your smartphone.
• 🔒 No need to pay for third-party apps (unlike many "Wi-Fi hacker" utilities on the Play Market).

However, there are also key limitations:

• 🚫 On Android 10+, even with root, you can access Wi-Fi configuration files (/data/misc/wifi/WifiConfigStore.xml) blocked due to SELinux And scoped storage.
• 🔐 Without root access, Termux cannot read system files where passwords are stored.
• ⚠️ Most "instructions" online are based on outdated versions of Android (before 8.0) and do not work on modern devices.

2. Legal Method: Retrieving Root Password

If your device has root-access, you can try extracting the password from system files. This method works. only for networks you are already connected to.

Steps:

1. Open Termux and update the packages:

   pkg update && pkg upgrade

2. Install the utility sqlcipher (needed to decrypt the Wi-Fi database):

   pkg install sqlcipher

3. Go to the Wi-Fi data directory:

   cd /data/misc/wifi

   ⚠️ Attention: On Android 11+ the path may be different (for example, /data/vendor/wifi/...). Use the command find /data -name "wifi" for search.

4. Copy the database WifiConfigStore.xml to an accessible directory (for example, /sdcard):

   cp WifiConfigStore.xml /sdcard/

5. Open the file with any text editor and find the line <string name="PreSharedKey"><your_password></string>.

If you see an encrypted string instead of a password, try decrypting it using sqlcipher:

sqlcipher -header "PRAGMA key='x''" /sdcard/WifiConfigStore.xml

Where x'' — encryption key (on some firmware versions this is an empty string) '').

3. Method without root: using ADB (only for native networks)

If you don't have root rights, but you have access to ADB (Android Debug Bridge), you can try extracting the password via a computer. This method works. only for networks to which the device has already connected.

Instructions:

1. Connect your smartphone to your PC and turn it on USB debugging V Settings → For developers.
2. Open the command prompt on your PC and run:

   adb shell
   su
   cat /data/misc/wifi/WifiConfigStore.xml | grep "PreSharedKey"

3. If the command returns an error Permission denied, then access is blocked SELinux.

An alternative option is to use ADB Backup:

adb backup -f wifi.ab -noapk com.android.providers.settings

Then unzip the file wifi.ab by using Android Backup Extractor and find Wi-Fi data in it.

4. Why most Termux hacks don't work

The internet is full of instructions like "install aircrack-ng in Termux and hack Wi-Fi in 5 minutes." In practice:

The main reasons for failure:

• 🔒 Android limitations: Since version 9.0, access to Wi-Fi files is blocked even for root users without kernel modification.
• 📵 Hardware limitations: Most smartphones do not support monitor mode (necessary for intercepting packets).
• 🛡️ Router protection: Modern protocols (WPA3, 802.11w) make intercepting a handshake virtually impossible without specialized equipment.

5. Alternative legal ways to get a Wi-Fi password

If Termux doesn't help, try these methods:

• 📋 Check the sticker on the router: On most models (TP-Link, ASUS, Keenetic) the password is indicated on the bottom panel next to the SSID.
• 🌐 Log in to the router's web interface:
  1. Connect to the network (even without the Internet).
  2. Open in browser 192.168.1.1 or 192.168.0.1.
  3. Log in (default logins: admin/admin, admin/1234).
  4. Go to Wireless → Security (names may differ).

If the router is rented from a provider (for example, Rostelecom or Beeline), the password can be specified in the contract or the subscriber’s personal account.

6. Risks and legal consequences of illegal access

Attempts to hack someone else's Wi-Fi network are classified as unauthorized access to computer information (Article 272 of the Criminal Code of the Russian Federation) and may entail:

• 💰 Fine up to 200,000 rubles (or the amount of one year’s salary).
• ⚖️ Correctional labor up to 480 hours.
• 🚔 Imprisonment up to 2 years (if the hack caused damage).

Besides:

• 📵 MAC address blocking: Modern routers automatically ban devices after several unsuccessful connection attempts.
• 🔍 Tracking: Providers record suspicious activity and may transfer the data to law enforcement agencies.
• 🦠 Viruses: Many "cracked" versions of Termux or APK files contain malware (for example, Triada or HiddenAds).

Important: Even if you are "just testing" your network, using tools like aircrack-ng or reaver without the explicit permission of the network owner (even if it's you) may be considered preparation for hacking.

7. How to protect your network from such attacks

If you're worried someone might try to hack your Wi-Fi, follow these steps:

• 🔐 Use WPA3: In the router settings, select WPA3-Personal (or WPA2/WPA3 Transition for compatibility).
• 🔄 Disable WPS: Protocol Wi-Fi Protected Setup vulnerable to brute force attacks (even if PIN is disabled).
• 📛 Change the default SSID: Don't use names like TP-Link_1234 — they reveal the router model and make it easier to find vulnerabilities.
• 🔄 Enable MAC address filtering: Allow connections only to known devices (although this is not a panacea - MAC addresses are easy to spoof).
• 🛡️ Update your router firmware: Outdated versions often contain critical vulnerabilities (eg. CVE-2019-14899 in ASUS routers).

Additionally:

• 🕒 Set up a Wi-Fi schedule: Turn off the network at night when no one is using it.
• 🌐 Create a guest network: For friends or IoT devices (smart lights, cameras), use a separate SSID with limited rights.
• 📡 Reduce signal strength: Reduce the transmit power in your router settings (for example, to 50%) - this will reduce the coverage area outside your apartment.
