How to connect to Wi-Fi if you don't know the password: all methods from simple to advanced

Unable to connect to Wi-Fi because you don't know or lost your password? There could be various reasons: resetting the router settings (for example, after pressing the Reset On TP-Link, Asus, or Keenetic), reinstalling Windows/macOS, lack of access to network settings in guest mode, or losing the password. Before attempting to bypass the protection, try simple solutions: look for the password on the router sticker (the model and factory key are often indicated), request it from the network owner, or restore it through the admin panel (192.168.0.1/192.168.1.1). If these methods don't work, we'll consider the following: All working methods for connecting to Wi-Fi without entering a password — from standard OS functions to advanced technical techniques.

It is important to understand: Unauthorized access to other people's networks is illegal. (In Russia, this is regulated by Article 272 of the Criminal Code of the Russian Federation). Therefore, all methods described below are applicable only to to their networks, for which you've lost the password, or to networks you're allowed to access (for example, in a cafe or hotel). Alternative authentication methods are often used for public hotspots—we'll cover those as well.

This article is structured from the simplest solutions (such as snooping on another device's password) to more advanced ones (like hacking WPS or analyzing traffic). Choose a method based on your technical expertise and the situation. And if you're a network administrator, you'll find tips at the end of the article on how to protect your Wi-Fi from unwanted connections.

1. View the saved password on an already connected device

The fastest and most legal way is to extract the password from a device already connected to the network. This could be your smartphone, tablet, laptop, or even a smart speaker. Let's look at how to do this on different platforms.

On Windows 10/11:

  1. Open Settings → Network and Internet → Wi-Fi.
  2. Click Managing known networks and select the desired network.
  3. Click Properties, then Show symbols under the field Network password.

On Android (root or ADB required):

  • 📱 Install the application WiFi Password Viewer (works on rooted devices).
  • 🔌 Connect your phone to your PC and use the ADB command:
    adb pull /data/misc/wifi/WifiConfigStore.xml

    In the resulting file, find the line PSK="your_password".

On MacOS:

  • 🍎 Open Programs → Utilities → Keychain.
  • 🔍 Enter the network name in the search, double-click on the entry and check the box Show password.
⚠️ Attention: On iPhone It's impossible to extract the password without jailbreaking. Apple blocks access to this information even through iTunes backups.

2. Use WPS to connect without a password

WPS (Wi-Fi Protected Setup) — is a technology that allows you to connect to a router without entering a password. It works through:

  • 🔢 PIN code (8 digits, often found on the router sticker).
  • 🔄 Button WPS on the router body (press it and the device will connect automatically).
  • 📱 NFC (rare, only on supported devices).

How to connect via WPS:

  1. Press the button on the router WPS (usually it is labeled or blinks after pressing).
  2. On your device (smartphone/laptop), select the desired network from the list and wait for the connection.
  3. If a PIN is required, enter it from the router sticker (usually it is a combination like 12345670 or 00000000).
Router model Location of the WPS button Default PIN
TP-Link Archer C6 On the side, next to the LAN ports On the sticker (8 digits)
ASUS RT-AX55 At the back, under the logo The last 8 digits of the MAC address
Xiaomi Mi Router 4A On top, under the lid 12345670
Keenetic Giga In front, next to the indicators Missing (button only)
⚠️ Note: Many modern routers disable WPS by default due to vulnerabilities. If the button doesn't work, check the settings in the router's web interface (192.168.1.1 or 192.168.0.1).

3. Connection via QR code (for modern routers)

Many new routers (for example, Huawei, Xiaomi, Keenetic) support QR code connection. This is convenient if:

  • 📱 You are a guest and the host can generate a QR code for you.
  • 🖼️ There is a sticker with a QR code on the router (sometimes hidden under the cover).
  • 🌐 The router can create temporary guest networks with QR access.

How does this work:

  1. On your smartphone, open the camera and point it at the QR code.
  2. The link will redirect you to the Wi-Fi settings, where you will be automatically connected.
  3. If the QR code is on the router, it can be scanned without the network owner's involvement.
Where can I find the QR code on my router?

On most models the QR code is located:

- On the bottom sticker (next to the SSID and password).

- In the router web interface in the section Wi-Fi → QR code for connection.

- In the manufacturer's mobile application (for example, Mi WiFi or Keenetic).

If there is no QR code, you can generate it manually through your router settings.

Examples of routers that support QR connection:

  • Xiaomi Mi Router 4/4A/4C — QR on the sticker.
  • Keenetic — QR generation in the web interface.
  • Huawei WS5200 — QR for the guest network.

4. Password recovery via the router's web interface

If you have physical access to your router, you can access its settings and view (or change) your Wi-Fi password. To do this:

  1. Connect to the router via cable (or via Wi-Fi if it doesn't have a password).
  2. Enter in your browser 192.168.1.1 or 192.168.0.1 (the address is indicated on the router sticker).
  3. Log in (default logins/passwords: admin/admin, admin/empty, admin/password).
  4. Go to the section Wi-Fi or Wireless network - there will be a field there Password or PSK.

If the default password doesn't work, the router may have been reconfigured. In this case:

  • 🔧 Reset your router to factory settings (button Reset for 10 seconds).
  • 📋 Use the data from the sticker (default SSID and password).
⚠️ Warning: Resetting your router will disconnect all users from the network and return all settings (including passwords, ports, and DNS) to factory defaults. Only perform this on your own equipment!

Try a different browser (Chrome, Firefox, Edge)

Check your cable connection (Wi-Fi may be disabled)

Make sure the router's IP address is correct (look at the sticker)

Reset the router using the Reset button (hold for 10-15 seconds) -->

5. Connect to the guest network (if enabled)

Many routers support guest network — a separate Wi-Fi network with limited access to local devices, but with internet access. Often a guest network:

  • 🔓 Does not require a password or has a simple password (eg. guest123).
  • 🕒 Works on a schedule (for example, only during the day).
  • 📶 Has a separate name (SSID) like MyWiFi_Guest.

How to find and connect to a guest network:

  1. Check the list of available networks for postfixes _Guest, _Public.
  2. Try default passwords: guest, public, 12345678.
  3. If the network is secured, but you know the owner, ask him to enable guest access in the router settings (Guest Network → Enable).

Examples of guest network settings on popular routers:

Router Path to guest network settings Max devices
TP-Link Additional settings → Guest network 10
ASUS Wireless Network → Guest Network 16
Keenetic Home Network → Segments → Guests Unlimited

6. Advanced Methods: Handshake Interception and WPS Brute Force

These methods are technically complex and may violate the law if applied to other people's networksWe describe them solely for educational purposes for security testing. his own networks.

Method 1: Handshake Interception (WPA/WPA2)

The gist: when a device connects to the network, an authorization packet is intercepted (4-way handshake), which is then cracked offline using a password dictionary. You will need:

  • 💻 Laptop with Kali Linux or Parrot OS.
  • 📡 Wi-Fi adapter with support monitor mode (For example, Alfa AWUS036NHA).
  • 🔑 Password dictionary (e.g. rockyou.txt).

Commands to intercept (in Kali Linux):

sudo airmon-ng start wlan0 # Enable monitor mode

sudo airodump-ng wlan0mon # Scan networks

sudo airodump-ng -c 6 --bssid [BSSID] -w capture wlan0mon # Capture handshake

sudo aircrack-ng -w /usr/share/wordlists/rockyou.txt capture-01.cap # Crack

Method 2: Brute-force WPS-PIN

A WPS vulnerability allows someone to brute-force an 8-digit PIN in a matter of hours. Tools:

  • 🛠️ Reaver or Bully (included in Kali Linux).
  • ⏱️ Time: from 2 to 10 hours (depending on the router).
sudo reaver -i wlan0mon -b [BSSID] -vv
⚠️ Attention: Modern routers (for example, ASUS RT-AX88U or Netgear Nighthawk) block WPS-PIN guessing after several unsuccessful attempts. This method only works on older models.

7. Alternative methods: Ethernet, USB tethering, SIM card

If you can't connect to Wi-Fi, consider these alternatives:

  • 🌐 Ethernet cableConnect your laptop directly to the router. This will give you access to the internet and router settings.
  • 📱 USB tethering: Share the Internet from your smartphone via USB (configure in Settings → Hotspot & Tethering).
  • 📶 Mobile Internet: Insert a SIM card with an unlimited tariff into the router (if 3G/4G is supported).
  • 🔄 Powerline adapters: Transmitting the Internet through electrical wiring (useful if Wi-Fi doesn’t work in another room).

Comparison of alternative methods:

Method Speed Complexity Restrictions
Ethernet 1 Gbps Low Need a cable
USB tethering Up to 50 Mbps Average Drains the phone's battery
4G router Up to 150 Mbps High A SIM card with a tariff is required

FAQ: Frequently asked questions about connecting to Wi-Fi without a password

Is it possible to connect to a neighbor's Wi-Fi if he didn't give me the password?

No, this is illegal (Article 272 of the Russian Criminal Code - "Unauthorized access to computer information"). The router's MAC address can be used to identify your device. If the network is open (without a password), using it can also be considered unauthorized access.

I reset my router, but the password on the sticker doesn't work. What should I do?

Possible reasons:

  • Sticker from another router (check the model).
  • The manufacturer has changed the default password (relevant for Xiaomi And Huawei).
  • The router was flashed with alternative firmware (for example, DD-WRT).

Solution: Connect to the router via cable and enter in the browser 192.168.1.1If it asks for login/password, try admin/admin or leave the password field blank.

How to protect your Wi-Fi from unwanted connections?

Recommendations:

  • 🔒 Use WPA3 instead of WPA2 (if the router supports it).
  • 🔄 Turn it off WPS in the router settings.
  • 📛 Hide your SSID (but this won't protect you from advanced users).
  • ⏱️ Set up MAC address restrictions (not the most reliable, but it will add complexity).
  • 🔄 Change your password regularly (every 3-6 months).
Is it possible to find out the Wi-Fi password using apps like WiFi Map?

Apps like WiFi Map, Instabridge or Wiman They collect passwords for open and public networks that users voluntarily share. The chances of finding a password for a private network there are minimal. Furthermore, such applications:

  • May contain malicious code.
  • Often shows outdated data.
  • Violate privacy policy (e.g. Google Play prohibits such functions).
What should I do if my router requires a login/password to access its settings, but I don't know them?

Standard combinations for different manufacturers:

  • TP-Link: admin/admin
  • ASUS: admin/admin
  • D-Link: admin/empty or admin/admin
  • Zyxel: admin/1234
  • Huawei: admin/password from sticker

If nothing works, reset the router using the button Reset (Hold for 10-15 seconds). After reset, use the data from the sticker.
