Many users are familiar with the situation of needing to connect a new device to their home network, but have forgotten the Wi-Fi password and the router is in a hard-to-reach location. Fortunately, modern smartphones have built-in features that make it easy to restore access to saved security keys without having to reset the router to factory settings.
In this article, we will take a detailed look at the standard tools of operating systems. Android And iOSWe'll also cover methods that require deeper intervention in the system. You'll learn how to find hidden access codes, use QR codes for quick device authorization, and understand the operating principles. WPA2/WPA3 encryption in the context of mobile devices.
It's worth noting that methods may vary depending on your smartphone's firmware version and router model. On devices running Android 10 and above, as well as iOS 16+, the password viewing feature is built into the standard settings menu without the need for root or jailbreak. If you have an older model, you will have to resort to alternative, but proven methods.
View saved networks on Android 10 and later
Starting with version 10, Google's operating system allowed users to directly manage passwords for saved networks through a standard interface. This was made possible by the implementation of a stricter security system, which, paradoxically, gave more control over data. To get started, you need to go to Settings → Connections → Wi-Fi.
In the list that opens, you'll see the currently active network and its connection history. Click the gear icon next to the desired network or select "Saved Networks" if you're looking for a hotspot key you're not currently connected to. In the menu for the selected network, look for the "Share" button or the QR code icon.
After verifying your identity using a fingerprint scanner, PIN, or pattern, the system will generate a QR code for quickly connecting other devices. This code typically displays a text string containing a password. If the text is hidden by dots, try taking a screenshot and opening it in Google Lens or any other QR code scanner—it will recognize the text automatically.
It is important to understand that on some custom shells, such as MIUI from Xiaomi or One UI The layout of elements may vary slightly from Samsung. However, the logic remains the same: look for the section related to data exchange or QR codes; this is where the symbol combination you're looking for is most often hidden.
⚠️ Note: On corporate devices or phones with MDM (Mobile Device Management) profiles installed, the administrator can block the ability to view passwords and create QR codes for security purposes.
How to find the password on an iPhone (iOS 16+)
Apple device owners were a little less fortunate in terms of the wait time for this feature, but starting with iOS 16, Apple has implemented a full-fledged password manager for Wi-Fi networks. Previously, this feature was only available through syncing with macOS, but now it can be done directly from your smartphone's screen.
To view the key, go to Settings → Wi-FiFind the network whose password you want to know in the list and click on the blue information icon (i) to the right of the name. In the menu that opens, find the "Password" line, which is hidden by dots by default.
Tap the password field. The system will require biometric authentication. Face ID or Touch IDOnce successfully confirmed, the dots will turn into readable text. You can copy the password to the clipboard or use it immediately to connect another device.
If you have an older version of iOS, the only legal way is to use Keychain Access on a Mac. Open the Keychain Access app on your Mac, find the name of your Wi-Fi network, double-click it, and check the "Show password" box. This will require you to enter the password for your Mac administrator account.
What to do if Face ID isn't working?
If biometrics aren't working, make sure you're not in lock mode (your phone has just been turned on). In this case, you'll need to enter the device's primary screen unlock code.
Using the ADB command line on older Android versions
For devices running Android 9 and below, there's no built-in way to view the password for security reasons. However, if you have a computer and a USB cable, you can use a tool. Android Debug Bridge (ADB)This method requires enabling developer mode, but does not require root access on most devices.
First, enable USB debugging in the Developer Options menu. Connect your phone to your PC, install the drivers, and install the platform. ADBOpen the command prompt on your computer and enter the command to access the system file where Wi-Fi configurations are stored.
adb shell cat /data/misc/wifi/wpa_supplicant.confIn the command output you will find blocks network, inside which there will be fields ssid (network name) and psk (password). Please note that on some modern smartphones, access to this file is blocked even via ADB without root access. In this case, this method will not work, and you will have to look for alternatives.
☑️ Getting Started with ADB
Login to the router's web interface
A universal method that works on any phone, regardless of OS version, is to access the router's settings. If you've ever changed the router's administrator password or it's still the default, you'll be able to see the Wi-Fi key in the wireless network section.
To do this, connect to the router's Wi-Fi network (you don't need a password if you've already saved one). Open your browser and enter the gateway IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1The exact address can be found in the Wi-Fi connection settings on your phone in the "Gateway" or "Router" field.
After entering your login and password (often admin/admin), go to the section Wireless or Wireless modeThere in the field Wireless Password, WPA Pre-Shared Key or similar, the current password will be displayed. You can not only view it but also change it to a more complex one.
| Router brand | Entrance address | Standard login | Standard password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Xiaomi | 192.168.31.1 | admin | (password from the sticker) |
Interfaces may vary between manufacturers, but the menu structure is generally the same. Look for tabs containing the words "Wireless Security," "WLAN," or "Security Settings." This is where your local network encryption keys are stored.
⚠️ Note: Interfaces and login addresses may vary depending on the router's firmware version. If the default addresses don't work, check your phone's network settings for the exact gateway IP address.
Password recovery apps
In app stores Google Play And App Store There are many utilities that promise to reveal saved passwords. However, be extremely cautious: most of them either don't work without root access or are data collectors. Only apps that can read QR codes or use special system APIs are truly useful.
One reliable option is to use file managers with access to system folders (root required). They allow you to open the file wpa_supplicant.conf in plain text. Without superuser rights, such apps are limited to QR code scanners or traffic analyzers, which are overkill for simply viewing a password.
It's best to avoid apps with names like "WiFi Password Hacker" or "Universal WiFi Key," as they often contain aggressive advertising and malicious code. Trust only trusted developers and carefully read the permissions the program requests during installation.
Problems and common mistakes
When attempting to enter a password, users often encounter technical limitations. For example, if the network is corporate (using a security certificate), the password may not be displayed in plain text, as authentication occurs through the certificate, not a static string of characters.
Another common issue is incompatibility of security protocols. If the router is configured to operate in WPA3If your phone is old, it may not display network settings correctly or may not display some settings fields at all. In such cases, it's best to use a computer for diagnostics.
- 📱 The screen goes blank when you enter the PIN to view the password - increase the screen timeout in the display settings.
- 🔒 The password field remains grayed out and inaccessible - you don't have administrator rights on this device or it's set to a restricted profile.
- 📶 The QR code cannot be read by another phone - check whether the screen is damaged or whether the brightness is too high, interfering with focusing.
It's also worth keeping in mind that after updating your phone's firmware, security settings may be reset or changed. In this case, the system may require you to re-enter your password for all networks, and old saved data may become inaccessible until the next successful login.
Why doesn't the password match the sticker on the router?
Most likely, the previous owner or you yourself changed the default password during initial setup. The factory key is only valid if the router's settings have been reset.
Questions and Answers (FAQ)
Is it possible to find out the Wi-Fi password if I've never connected to it?
No, that's impossible. A phone can't find the password for a network it doesn't have access to and has never connected to. This would require cracking the encryption, which is practically impossible to do from a mobile device with modern WPA2/WPA3 protocols.
Where is the password file physically located on Android?
The system file is called wpa_supplicant.conf and is located along the way /data/misc/wifi/Access to this directory without root (superuser) rights is closed to regular applications and the user.
Is it safe to use a QR code to connect guests?
Yes, it's secure. The QR code contains an encrypted string with the network name and password. It doesn't reveal your password in plain text to anyone unless they physically scan the code. However, don't post screenshots of the code publicly.
What should I do if the Share button doesn't show the password in plain text?
Take a screenshot of the screen containing the QR code. Then open this screenshot in Google Photos or any other QR code scanner. The app will recognize the code and reveal a hidden text string with a password beneath the image.
