Many users are familiar with the situation of urgently needing to access the internet but losing or forgetting their wireless network password. This often happens when purchasing a new smartphone or tablet, but older devices already have access to the router, but the new login credentials are unknown. Fortunately, modern operating systems and network equipment offer several legal ways to solve this problem without breaking the encryption.
In this guide, we'll cover exclusively legal methods for accessing a local network that you own or have permission to use. We'll cover using QR codes, the WPS function, and how to view saved keys in Android and iOS settings. Data security remains a priority, so all the methods described below require at least minimal physical access to the already connected device or the router itself.
It is worth noting right away that It is impossible to connect to a WPA2/WPA3 secured network without knowing the key or having an authorized device nearby, unless the router has the outdated WPS protocol or guest access feature enabled. Modern encryption algorithms reliably protect traffic from third-party intrusion, making brute-force attacks ineffective and illegal for the average user.
Using a QR code for quick authorization
The simplest and most modern way to share network access is using a QR code. If you have an Android smartphone already connected to the desired Wi-Fi network, you can generate a code for another device. This feature is built into the Android OS starting with version 10 and doesn't require any third-party apps.
To do this, go to the wireless network settings, select the desired access point, and click the "Share" button or the gear icon. An image will appear on the screen, which you can scan with the second phone's camera. iPhone also supports scanning such codes via the standard Camera application.
- 📱 Open Wi-Fi settings on an already connected device.
- 📸 Click the "Share" button or "QR code".
- 🔍 Point the camera of your new phone at the code that appears.
- ✅ Confirm the connection on the new device.
⚠️ Warning: The QR code contains the cleartext password. Do not take screenshots of this code or send them to strangers, as anyone who sees the image will be able to access your network.
Connection via WPS protocol
Technology Wi-Fi Protected Setup Wi-Fi Protected Setup (WPS) was developed to simplify connecting devices to a wireless network without entering long passwords. While many modern routers disable this feature by default for security reasons, it is often enabled on older models. This method allows authentication by physically pressing a button on the router.
To use this method, look for a button on the back of your router that says WPS or the two arrows icon. Press and hold it for 2-3 seconds until the indicator light flashes. Then, on your phone, select your access point from the list of available networks—the system will automatically request a connection without entering a key.
Why is WPS considered insecure?
The WPS protocol is vulnerable to brute-force attacks. Attackers can recover the network password by guessing the 8-digit PIN, which takes just a few hours. Therefore, experts recommend disabling this feature in your router settings if you're not using it.
It's important to understand that many modern smartphones running Android 9 and above have removed WPS support via the software interface. In these cases, connection is only possible if the phone's operating system has built-in driver support for this protocol.
Viewing a saved password on Android
If your device is running Android 10 or later and has previously connected to the desired network, you can view the saved password in Settings. This will allow you to manually enter the passkey on any other device, including laptops or game consoles.
To view data, go to the Settings menu and select "Wi-Fi" or "Connections." Tap the network name or the gear icon next to it. In the menu that opens, find "Share" or "QR code." A text string containing the password, hidden by asterisks, is often displayed beneath the code image.
To view the symbols, click the eye icon. If the password isn't displayed in text, you can take a screenshot of the QR code and open it with Google Lens, which will recognize and display the security key text string.
- 🔑 Go to
Settings → Wi-Fi. - 📲 Select an active network.
- 👁️ Click "Show password" or scan your QR code.
⚠️ Please note: On some smartphone models (e.g. Xiaomi, Samsung), viewing the password may require identification via fingerprint, Face ID, or entering the screen unlock PIN.
Connection Features on iPhone (iOS)
In the ecosystem Apple Data security is our top priority, so directly viewing saved Wi-Fi passwords is only available in iOS 16 and iPadOS 16. If you have an older version of the operating system, viewing the key in plain text will not work without using a backup on your Mac.
For devices with the latest firmware, open "Settings," go to the "Wi-Fi" section, and tap the blue information icon (the letter "i" in a circle) next to the network name. In the "Password" field, tap the hidden dots, after which the system will prompt you to complete biometric verification (Face ID or Touch ID). After successful authentication, the password will be displayed in plain text, which you can copy.
There's also a feature for automatically sharing passwords between Apple devices. If your iPhone is already connected to a network and a friend approaches you with their iPad or MacBook and tries to select the same network, a pop-up window will appear on your screen asking if you want to share the passkey. Simply tap "Share Password," and the connection will be established automatically on the other device.
| iOS version | View password | Automatic exchange | Requirements |
|---|---|---|---|
| iOS 16 and later | Yes (in settings) | Yes | Face ID / Touch ID |
| iOS 14-15 | No (only via Mac) | Yes | Contacts in the address book |
| iOS 13 and later | No | Yes | Bluetooth is on |
Using the router's web interface
If you have physical access to the router and can connect a computer or phone to it via cable (or if you're already connected via Wi-Fi but want to know the password for others), you can use the admin panel. To do this, you'll need to know the login address (usually 192.168.0.1 or 192.168.1.1) and administrator login and password.
Open your browser and enter the router's IP address in the address bar. After entering your credentials (often by default this is admin/admin, if they haven't changed) go to the wireless network section. It may be called Wireless, Wi-Fi Settings or "Wireless Mode." There in the field Wireless Password or Pre-Shared Key The current key will be indicated.
☑️ Checking access to the router
If the default login details were changed previously and you don't remember them, the only legal option is to reset the router to factory settings. To do this, you'll need to find the hole. Reset On the case, press it with a paperclip and hold for 10-15 seconds. After rebooting, the router will have the password indicated on the sticker on the bottom of the case.
⚠️ Warning: Resetting your router will disconnect all devices from the network and restore factory settings, including the network name and password. Make sure you have the connection settings from your internet service provider (PPPoE, username, and password) if they are required to configure the WAN port, otherwise your internet may stop working.
Guest network as an alternative solution
Many modern routers support a guest network. This is a separate access point with its own name and password, isolated from your main local network. This is ideal if you need to give access to friends but don't want to share your main password or risk the security of your devices.
You can set up a guest network through the router's web interface. Typically, this only requires activating the corresponding switch in the Wi-Fi section, setting a name (SSID), and a simple password. You can often set a time limit or speed cap, which is a great feature. network hygiene.
Using guest access eliminates the need to change your master password if you've shared it with someone who should no longer have access to your network. You can simply change the guest network password or disable it with one click.
Frequently Asked Questions (FAQ)
Is it possible to connect to a neighbor's Wi-Fi without a password legally?
No, connecting to someone else's network without the owner's permission is illegal and violates computer security laws. All methods described in this article assume you have access rights to the network (either the owner or you have received permission).
What should I do if the WPS button on my router doesn't work?
The WPS function can be disabled in the router settings. Check the wireless security section of the device's web interface. This function may also not be supported on very old or new router models for security reasons.
Why doesn't my phone see the QR code for Wi-Fi?
Make sure the camera focuses correctly and there's no glare on the screen. If the code is damaged or too small, try increasing the screen brightness. Also, make sure the code format is correct (Wi-Fi Alliance standard).
Are password recovery apps safe to use?
Most of these apps are either useless or contain ads and malware. They can't hack a modern password. The only thing they can do is reveal the saved password if the phone is rooted, which itself weakens the device's security.
How do I find out my password if I'm connected but don't remember it?
Use the methods described in the sections for Android (QR code/settings) or iOS (settings with Face ID). If you don't have your device handy, your only option is to access the router settings through a browser if you remember the administrator password.
