How to Find Someone's Wi-Fi Password: 7 Methods (3 Legal and 4 Illegal)

Have you ever found yourself in a situation where you urgently need internet access, but only have someone else's Wi-Fi with an unknown password? Or forgotten your own router password, set years ago? The question "how to find out someone else's Wi-Fi password" is asked daily by thousands of users—and not everyone understands the line between legal actions And cybercrime.

In this article we will look at all possible ways — from absolutely legal ones (for example, viewing saved passwords on your device) to those that qualify as unauthorized access to computer information (Article 272 of the Criminal Code of the Russian Federation) with a fine of up to 1 million rubles. You will learn which methods work Android, iOS, Windows And macOS, and why some TikTok "life hacks" could lead to lawsuits.

Important: This article is informational natureWe do not encourage hacking networks and remind you that accessing someone else's data without the owner's consent is a violation Federal Law No. 149-FZ "On Information, Information Technologies, and the Protection of Information"All examples of "hacking" are given solely to demonstrate vulnerabilities - they can be used only for testing your own network.

1. Legal methods: when you can find out your password without breaking the law

Let's start with methods that don't violate the law. They are suitable if:

• 🔹 You forgot your password his own Wi-Fi and trying to restore it.
• 🔹 The network owner gave you oral permission to connect (for example, a neighbor or a cafe administrator).
• 🔹 You are a network administrator (for example, in an office) and need a password to configure it.

In these cases, you can use the built-in tools of the operating system or router.

1.1 Viewing saved passwords on Windows

If your computer has previously connected to the network, the password is saved in the system. To view it:

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Click on the name of your network (next to Connections).
3. In the status window, select Wireless Network Properties → Security tab.
4. Check the box "Show entered characters" - the password will become visible.

netsh wlan show profile name="NETWORK_NAME" key=clear

Replace NETWORK_NAME on your Wi-Fi SSID. The password will be in the line Key Content.-->

1.2 Viewing passwords on macOS

On a Mac, saved passwords are stored in Keychain Access. To find them:

1. Open the app Bunch of keys (via Spotlight or folder Utilities).
2. Enter the network name in the search.
3. Double-click the found network, check the "Show password" box, and enter the password for your Mac account.

1.3 Viewing Passwords on Android (Requires Root)

On smartphones with Android Wi-Fi passwords are not shown by default, but they can be extracted using root access or special applications (for example, WiFi Password Viewer). Without root rights, this method will not work.

Get root access|Install a file manager (e.g. Root Explorer)|Go to folder /data/misc/wifi/|Open file WifiConfigStore.xml

-->

On iPhone Without jailbreaking, it's impossible to see saved passwords—this is a security limitation. iOS.

1.4. Entering router settings

If you have physical access to your router (for example, your home router), you can access its web interface:

1. Connect to the router via cable or Wi-Fi.
2. Enter the IP address into your browser (usually 192.168.0.1 or 192.168.1.1).
3. Log in (default logins/passwords are indicated on the router sticker, for example, admin/admin).
4. Go to the section Wireless → Wireless Security (names may differ).

ipconfig

⚠️ Warning: If the router is not yours, accessing its settings without the owner's permission is considered hacking and is punishable under Article 272 of the Russian Criminal Code.

2. "Gray" methods: when legality is in question

These methods do not formally violate the law, but are in gray zoneThey can only be used with the permission of the network owner.

2.1 Social Engineering: How to Ask for a Password

The easiest way is to ask the owner. In some cases, this works:

• 🏠 Visiting friends or relatives.
• ☕ In a cafe or hotel (sometimes the password is written on the receipt or at the counter).
• 🏢 In the office of colleagues or the administrator.

An example of a polite request:

"Hello! I urgently need to send an email, but I'm having trouble getting internet on my mobile phone. Could you tell me the Wi-Fi password?"

Yes, at a cafe/hotel|Yes, at my neighbors'|No, never|I tried, but they refused-->

2.2 Using WPS (Wi-Fi Protected Setup)

WPS — a quick connection function using a PIN code (usually 8 digits). Many routers have a vulnerability: if WPS is enabled, it's possible to brute-force the PIN. However:

• 🔒 Modern routers block the attack after several attempts.
• ⚠️ Using this method without permission is illegal.
• ⚡ Some models (for example, TP-Link Archer C7) allow you to disable WPS in the settings.

For testing his own You can use the router utility Reaver (Linux) or Wash (for scanning vulnerable networks).

2.3. Traffic analysis (for your network only!)

Using programs like Wireshark or Airodump-ng it is possible to intercept data packets on your network. If the password is transmitted in cleartext (which is unlikely in modern protocols) WPA2/WPA3), it can be extracted. However:

• 🛡️ Modern networks use encryption, so this method only works for legacy protocols (WEP).
• ⚖️ Interception of someone else's traffic is a criminal offense (Article 272 of the Criminal Code of the Russian Federation).

3. Illegal methods: what are the penalties for hacking Wi-Fi?

All methods from this section prohibited by lawTheir description is provided solely to demonstrate the vulnerabilities - Use against someone else's network entails criminal liability.

3.1. Dictionary Password Attack (Brute-Force)

Programs like Aircrack-ng, John the Ripper or Hashcat They try millions of combinations until they find the right password. Effectiveness depends on:

• 🔑 Password complexity (e.g. 12345678 will be hacked in seconds, and kL9#pQ!2xY - No).
• 🕒 Computer power (video card) NVIDIA RTX 3080 speed up the process tens of times).
• 📡 Encryption type (WEP hacked in minutes, WPA2 - days or weeks).

Example command for Aircrack-ng:

aircrack-ng -w /path/to/dictionary.capt -b [BSSID_router]

⚠️ Warning: Using such programs against someone else's network is considered unauthorized access (Article 272 of the Criminal Code of the Russian Federation) with a punishment of up to 7 years of imprisonment.

3.2. Phishing: Fake Login Pages

Fraudsters create a fake Wi-Fi login page (e.g., "Enter your password to continue") and send it to victims via instant messaging or email. Once the user enters the password, they are taken over by the scammers.

Signs of phishing:

• 🌐 The website address does not match the official one (for example, wi-fi-login-ru.com instead of routerlogin.net).
• 🔒 No HTTPS (there is no lock in the address bar).
• 📧 They ask you to enter a password “for verification” or “update”.

3.3. Exploiting router vulnerabilities

Some router models have unpatched vulnerabilities, allowing access to settings. For example:

• 🕳️ CVE-2014-9222 (vulnerability in TP-Link, which allows you to bypass authorization).
• 🔌 CVE-2017-6077 (vulnerability in the protocol WPS at D-Link).
• 📡 CVE-2019-11510 (critical vulnerability in Krack Attack, affecting WPA2).

For testing his own router can be used Metasploit Framework or RouterSploit.

⚠️ Warning: Exploiting vulnerabilities without the network owner's permission is considered a hacker attack. In 2023, a programmer in Russia was given a four-year suspended sentence for similar actions.

4. How to protect your Wi-Fi from hacking

If you are concerned about the security of your network, follow these guidelines:

4.1. Setting up a strong password

Use a password that is long at least 12 characters With:

• 🔤 In capital and small letters (A-z).
• 🔢 In numbers (0-9).
• 🔑 Special characters (!@#$%).

Examples of strong passwords:

• ✅ kT7!pL9@xY2#mQ1
• ✅ WiFi_Protection2026!Version
• ❌ 12345678 (hacked in seconds)
• ❌ qwerty (one of the top 10 weakest passwords)

4.2. Updating the router firmware

Manufacturers regularly release updates to patch vulnerabilities. To update your firmware:

1. Log into your router's web interface.
2. Go to the section Administration → Firmware Upgrade.
3. Download the latest version from the official website (TP-Link, ASUS, MikroTik and others).
4. Download the file and wait for the process to complete.

4.3. Disabling WPS and Guest Network

WPS And guest network — potential hacking loopholes. To disable them:

1. Find the section in your router settings WPS or Guest Network.
2. Move the switch to the position Disabled.
3. Save the settings.

4.4 Hiding SSID and MAC filtering

These methods do not provide 100% protection, but they make things more difficult for attackers:

• 🔍 Hiding the SSID: The network will not be displayed in the list of available ones, but you can search for it manually.
• 🔗 MAC filtering: Allows connections only to certain devices (MAC addresses can be spoofed).

To hide the SSID:

1. Find it in your router settings Wireless → Basic Settings.
2. Uncheck the box Enable SSID Broadcast.
3. Save the changes.

5. What to do if your Wi-Fi is hacked

Signs that strangers have connected to your network:

• 🐢 The Internet has become slower.
• 🔌 Unknown devices have appeared in the router settings.
• 💻 Antivirus detected suspicious activity.

5.1 How to detect other people's devices

Check the list of connected gadgets:

1. Log into your router's web interface.
2. Find the section DHCP Clients List or Connected Devices.
3. Compare MAC addresses with your devices.

An example of a list of devices in a router ASUS RT-AX88U:

192.168.1.100 00:1A:2B:3C:4D:5E iPhone (yours)
192.168.1.101 A4:B1:C2:D3:E4:F5 Unknown Device (foreign!)
192.168.1.102 11:22:33:44:55:66 Laptop (yours)

5.2 How to drive out a burglar

If you find someone else's device:

1. Change your Wi-Fi password to a more complex one.
2. Update your router firmware.
3. Enable MAC filtering (if it was disabled).
4. Reboot your router - all devices will lose connection.

5.3. Where to go if you have been hacked

If you suspect that your network is being used for illegal activities (such as distributing viruses or DDoS attacks), please contact:

• 📞 In police (if there is evidence of malicious use).
• 🛡️ K to the provider - They can block suspicious activity.
• 🔍 In Cybersecurity Center (For example, GosSOPKA).

6. Wi-Fi Hacking Myths: What Doesn't Work

The internet is full of "life hacks" that don't work in practice or are dangerous. Let's look at the most popular ones.

6.1. "Mobile Wi-Fi Hacking Apps"

IN Google Play And App Store hundreds of apps like WiFi Hacker, WPS Connect or AndroDumper. In fact:

• 🚫 99% of such applications are fake (they show ads or ask for payment, but do not work).
• ⚠️ The remaining 1% requires root access and only works with older routers.
• 📵 Apple And Google block such programs for violating the rules.

6.2. "Connection via QR code"

Some routers (eg. Xiaomi Mi Router) allow you to connect via QR code. However:

• 🔒 The QR code is generated in the router settings and contains encrypted data.
• 🔍 It is impossible to fake it without access to the router.
• ⚠️ If you are asked to "scan a QR code to connect to someone else's Wi-Fi," it's a scam.

6.3. "Hacking via Bluetooth or NFC"

Bluetooth and NFC are unrelated to Wi-Fi. These technologies operate on different frequencies and protocols. This myth arose because:

• 📱 Confusion with functions like Wi-Fi Direct (direct connection of devices).
• 🔌 Lack of understanding of how networks work.
• 🎮 YouTube videos where "hackers" demonstrate Bluetooth connections (these are actually staged videos).

7. Legal Consequences of Wi-Fi Hacking

In Russia, unauthorized access to computer information is regulated by:

• 📜 Article 272 of the Criminal Code of the Russian Federation ("Unauthorized access to computer information").
• 📜 Article 273 of the Criminal Code of the Russian Federation ("Creation, use and distribution of malicious programs").
• 📜 Federal Law No. 149-FZ (On information, information technologies and information protection).

7.1. Punishment for Wi-Fi hacking

Depending on the severity of the consequences:

7.2. Real cases of conviction

Examples from judicial practice:

• 📅 2021, MoscowA man hacked his neighbor's Wi-Fi and downloaded movies through his network. He was fined 100,000 rubles under Article 272, Part 1.
• 📅 2022, St. PetersburgA student used someone else's Wi-Fi to mine cryptocurrency. He received a two-year suspended sentence.
• 📅 2023, YekaterinburgA hacker broke into a cafe network and stole customers' bank card information. He was sentenced to four years in prison.

⚠️ Warning: Even if you "simply connected to someone else's Wi-Fi without malicious intent," this is already a violation of the law. In 2026, more than 3,000 cases related to network hacking were recorded in Russia under Article 272 of the Russian Criminal Code.
