Needing to connect a new device to a wireless network but forgetting the password is a common occurrence. Many users immediately start searching for complex solutions, downloading dubious utilities, or even planning to reflash the router, neglecting the standard operating system functions. Android make it easy to retrieve saved authorization data using standard tools if the device has previously successfully connected to the access point.
You will not need to receive root rights, which often result in warranty voiding and disruption of banking apps. All you need is access to the settings menu and, in some cases, another device with a camera. This method is safe, doesn't require installing additional software, and only takes a couple of minutes, even for an inexperienced user.
It's important to understand that the ability to view a password in plaintext directly depends on the operating system version. On older versions Android (before 9th) this functionality was hidden, but starting from Android 10 Google has introduced a convenient QR code generation mechanism that solves the problem of forgotten access keys.
Checking Android version and compatibility
Before you begin, make sure your device supports network key viewing. This feature has become the de facto standard for most smartphones released after 2019. If you have an older device, the methods may differ, but the algorithm is the same for current models.
To check the firmware version, go to the menu Settings → About phone → Android versionIf the version number is 10 or higher, the standard method is guaranteed to work. Owners of devices with version 9 and below will have to find workarounds, such as accessing the password in the router interface, as the system password storage is protected differently.
Shell interfaces from different manufacturers such as Samsung, Xiaomi or Huawei, may differ slightly in the arrangement of menu items. However, the system's logic remains the same: the encryption key is stored in a secure area, accessible after the owner's identity is confirmed via biometrics or a PIN code.
It's worth noting that on some enterprise or heavily modified OS builds, access to these settings may be restricted by the device administrator. In this case, standard methods won't work, requiring the intervention of an IT specialist or a network settings reset.
View your password via QR code on Android 10 and later
The easiest and most reliable way to find a forgotten key is to use the built-in QR code generator. This method doesn't require complex commands or a computer connection. All you need is access to Wi-Fi settings and a camera on a second smartphone or a barcode scanner.
To get started, open the section Settings on your phone and select the item Wi-Fi or ConnectionsFind the network you need to find the password for in the list. Important: Your device must be currently connected to this network or have a record of a previous successful connection.
Click on the network name or the gear icon next to it. In the menu that opens, find the button Share or a QR code icon. The system will ask you to confirm your action by entering your pattern, fingerprint, or Face ID. Once confirmed, a square code will appear on the screen.
Now the second smartphone comes into play. Open the camera or a QR code scanning app on it and point the lens at the first phone's screen. A pop-up notification will show the connection string, with the following prefix: P: The password you are looking for will be indicated.
☑️ Action Algorithm
⚠️ Warning: Do not take a screenshot of the QR code or send it to anyone. This code contains the full access key, and anyone who scans it will be able to connect to your network without your knowledge.
What to do if the button does not appear?
On some skins (such as MIUI or OneUI), the button may be hidden in a submenu. Try long-pressing the network name or searching for "More." If the option isn't there at all, the manufacturer may have limited this feature for your model.
Using Google Lens to transcribe
If the second device does not have a special scanner, the built-in service will come to the rescue Google Lens (Lens). It's integrated into the Google app or the camera on many smartphones and allows you to not only read the code but also immediately initiate a connection.
Launch the Google app on the second device and tap the camera icon. Point the camera at the QR code displayed on the first phone. The system will recognize the data type and offer a text password or a "Connect" button.
Advantage of using Google Lens Its advantage lies in its versatility. It works equally well on devices running stock Android and on devices with heavy skins. Furthermore, the service can recognize text even from poor-quality images, even if the primary phone's camera has a low resolution.
In some cases, instead of an explicit password, the system may prompt you to add a network. If you're specifically looking for the password, pay close attention to the tooltips above the connect button. The access key is often duplicated there in small print.
Comparison of access recovery methods
There are several ways to retrieve access, but they vary in complexity and requirements. Below is a table to help you choose the best option based on your situation and the availability of additional devices.
| Method | Root is required | Need a second phone | Complexity |
|---|---|---|---|
| QR code (standard) | No | Yes (for scanning) | Low |
| Google Home | No | No | Average |
| Router settings | No | No | Average |
| wpa_supplicant file | Yes | No | High |
As the comparison shows, the QR code method is the most accessible to the average user. It doesn't require extensive technical knowledge and is system-safe. The configuration file option is mentioned only for completeness, as it requires superuser privileges, which we excluded from the problem specifications.
Using the application Google Home It's also possible if your router is supported by this service and you've previously configured the network through it. In this case, the password can be found in the device card under "Settings" → "Share." However, this method doesn't work with all router models.
Alternative methods without installing programs
If for some reason viewing the QR code isn't possible (for example, the screen is broken or the touchscreen isn't working), you can try accessing the router's web interface. To do this, your phone must be connected to Wi-Fi, even if the internet isn't working.
Open your browser and enter the gateway IP address into the address bar, which usually looks like this: 192.168.0.1 or 192.168.1.1This information can also be found in your phone's network settings under "Details" or "Network Properties."
You'll need to enter your router administrator login and password. If you haven't changed them, they're often found on a sticker on the bottom of the device (the default is admin/admin). In the router menu, find the "Admin" section. Wireless or Wireless mode → Wireless SecurityThe password will be shown there in clear text.
⚠️ Note: Router interfaces are constantly being updated. The layout of menu items may vary depending on the model (TP-Link, ASUS, Keenetic, MikroTik). If you can't find the item you need, check the manual for your specific device.
Another option is to use Google's password sync feature. If you have sync enabled, your password may be saved to your Google account. You can check this on your computer by going to your Google account settings → Security → Password Manager. Find your Wi-Fi network there.
Common errors and problems during recovery
Users often encounter problems with nothing happening when they tap the "Share" button, or with the code not being read. This may be due to the screen being dimmed on the first phone. Increase the display brightness to maximum so the second device's camera can clearly read the sensor.
Another common issue is image scaling. If the QR code doesn't fit within the scanner's frame, move your phone away or use the camera's zoom feature. Also, make sure the camera lens is free of any dirt or debris that could distort the image.
Sometimes the system requires an internet connection to verify the network before displaying the password. If the router doesn't have access to the external network, the phone may block the code display for security reasons. In this case, try temporarily connecting to mobile data.
Wireless network security measures
Once you've learned the password, it's a good idea to consider your network's security. If the access key was simple or easy to guess, it's best to change it. You can do this through the router's web interface in the security section.
Use complex character combinations that include mixed-case letters, numbers, and special characters. Avoid using birth dates, phone numbers, or sequences like 12345678Modern encryption standard WPA3 (or at least WPA2) is required to protect against hacking.
Regularly check the list of connected clients in your router settings. If you notice an unknown device, change the password immediately and block the uninvited guest's access. Remember that access to your network allows attackers to intercept traffic.
Don't store passwords as screenshots in a public gallery. Instead, use Google's built-in password manager or specialized secure vaults. This will protect your data if you lose your phone or sell it.
Is it possible to find out the password if the phone has never connected to this network?
No, this is technically impossible without access to the router itself. The phone only stores the keys used for successful authorization. If the device doesn't know the password, it won't be able to display it or generate a QR code.
Is it safe to use third-party password recovery apps?
Most of these apps require root access, which compromises system security. Furthermore, they often contain ads or collect data about your networks. Android's built-in methods are significantly safer and more reliable.
What to do if the QR code is not readable by any device?
Try taking a screenshot of the QR code, opening it in Google Photos, and using the "Search by Image" feature (Google Lens). The built-in image analyzer often does a better job than the real-time camera.
Will the router password be reset if I look at it on my phone?
No, viewing the password through your phone settings or a QR code is a passive operation. No changes are made to the router's configuration, the network continues to operate normally, and other devices will not be disconnected.
