Smartphone users often face a situation when they need to connect a new gadget to the Internet, but the password for their home network is lost or forgotten. In the ecosystem Android this parameter is technically called network security key. Finding it is not always obvious, since interface manufacturers hide this information in different sections of the menu, and sometimes even require root access to view saved data.
However, modern versions of the operating system, starting from Android 10 and higher, have greatly simplified this process. Now you can not only view the current password, but also instantly transfer it to another device via QR code. In this article, we will look at all the legal ways to obtain a key, the nuances of working with access points, and methods for restoring access if standard paths are blocked by the system.
It is important to understand that a “security key” can mean different things in different contexts: it could be the password from your home router or the encryption key generated when creating a personal access point. We will look at both options so that you can solve any connection problem.
Searching for a password in the access point settings
The most common scenario is the need to distribute the Internet from your phone to a laptop or tablet. In this case, the smartphone itself acts as a router, and security key is set by you manually or generated by the system. To find out or change this code, you need to go to the corresponding settings menu.
The path to the settings may differ slightly depending on the manufacturer's shell (MIUI, OneUI, Pixel UI), but the logic remains the same. You need to find the section responsible for wireless connections and select the modem function. The current password is displayed here, which can be copied or replaced with a more convenient one to remember.
Please note that in some older firmware versions the password field may be hidden by default. In this case, the system will prompt you to simply enter a new code without showing the old one. If you have not changed the settings before, check the manufacturer's label on the device, although this is rare for software access points.
⚠️ Attention: When you change the security key in the access point settings, all connected clients will be immediately disabled. They will need to enter a new password to reconnect.
For quick navigation, use the following algorithm:
- 📱 Open the application

Setting up an access pointto see the password field.
Use complex passwords (minimum 8 characters, letters and numbers) for an access point so that neighbors cannot use your mobile traffic for free.
View the password for a saved Wi-Fi network
If your phone is already connected to your home or office network, you can easily find out its security key. This function has become a standard in Android 10+. The system allows you to view saved credentials without having to enter a master password if the screen has already been unlocked (via fingerprint, face or PIN).
The process is intuitive. In the Wi-Fi menu, a gear or arrow icon often appears next to the name of the active network. By clicking on it, you are taken to a detailed description of the connection. There, at the bottom of the screen or in the drop-down list, there is a "Share" button or an eye icon.
By clicking on the share button, the system will generate QR code. Under this code, as a rule, a text string with a password is displayed in small font. This is the fastest way to transfer access to guests: they do not need to dictate complex combinations of symbols, just point the camera.
| Android version | Viewability | Requirements | Method display |
|---|---|---|---|
| Android 9 and below | No (without Root) | root access | Via file manager |
| Android 10 | Yes | Unlocking the screen | QR code + text |
| Android 11-13 | Yes | Biometrics/PIN | QR code + text |
| Android 14+ | Yes | Biometrics/PIN | Copying a password |
Using a QR code to transfer access
Technology QR codes has become an indispensable tool in managing network connections. When you see a generated square barcode on your phone screen, know that the full connection string is encrypted inside it, including the encryption type (WPA2/WPA3), network name (SSID) and the security key itself.
To connect another device, you do not need special applications. It is enough to open the standard camera on a second smartphone or tablet. Modern cameras automatically recognize the Wi-Fi format and offer to connect to the network with one click. This eliminates errors when manually entering characters.
In the latest updates Android it became possible not only to generate, but also to scan codes directly from the Wi-Fi settings menu. This creates a convenient data exchange loop: you can quickly transfer settings between your devices or guests without further ado.
What to do if the QR code is not read?
If the camera does not recognize the code, try increasing the brightness of the source smartphone screen to maximum. Also make sure there is no dirt on the second device's camera lens. As a last resort, take a screenshot of the code and open it through the Google Lens application or any QR scanner.
Remember that a screenshot with a QR code contains your password in clear text (if it is displayed in the text under the code). Do not send such images to public chats or to strangers, as this gives them full access to your local network.
Viewing saved networks on older versions of Android
Owners of devices with lower system versions Android 10 are in a less advantageous position. For security reasons, Google has closed direct access to Wi-Fi configuration files for regular apps. The system stores the keys in a protected system partition, to which only the superuser has access.
If you do not have root access, it is impossible to view the password using standard means. The only legal way in this case is to go into the settings of the router itself. To do this, you need to connect your phone to the network (even if you don’t know the password, but the connection has already been established) and go through the browser to the IP address of the gateway.
Usually the router address looks like 192.168.0.1 or 192.168.1.1. By entering these numbers into the address bar of your browser, you will be taken to the administrator page. There, in the wireless security section (Wireless Security), you can see or change the network key.
⚠️ Attention: The interface of routers from different manufacturers (TP-Link, Asus, D-Link) is very different. If you do not remember the login and password from the router's admin panel, you may need to reset the device to factory settings using the button
Reset.
For advanced users with superuser rights, there is a path through the file system. The configuration file is usually located on the path /data/misc/wifi/wpa_supplicant.conf. By opening it with a text editor with root access, you will see a list of all networks and their passwords in the field psk.
☑️ Actions in the absence of root access
Resetting the network settings and restoring access
Sometimes a situation arises when the phone “forgot” the network and password lost, but there is no access to the router. In such cases, a complete reset of network settings helps. This operation will not delete your photos or contacts, but will clear all saved Wi-Fi networks, Bluetooth pairings and mobile hotspot settings.
After the reset, the phone will search for networks as a new device. If you know the password for the router (for example, it is listed on the sticker below), you can enter it again. If the password is unknown, this step will become a preparatory step before reconfiguring the router itself.
You can perform a reset through the settings menu. The path usually looks like this: Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings. Confirm the action and the phone will reboot the network modules.
This method is also effective if you encounter connection errors when the phone sees the network, but endlessly tries to obtain an IP address or gives an authentication error. Clearing the network protocol cache often solves the problem of encryption incompatibility.
Resetting network settings is a secure operation for personal data, but it will require you to re-enter passwords for all known Wi-Fi networks.
Issues with encryption and compatibility
Modern security standards such as as WPA3can create conflicts with older devices. If your new phone does not see the network or cannot connect to the old router, the problem may lie in incompatibility of encryption protocols. Android 14 does not see the network or cannot connect to the old router, the problem may lie in the incompatibility of encryption protocols.
In the settings of the access point on Android, you can select a security mode. The default is often WPA2-Personal, which is the most compatible option. If you accidentally set WPA3 or the "Open Network" (no password) mode, some devices may refuse to connect for security reasons.
In addition, it is worth checking the frequency range. Some old gadgets do not see the network 5 GHz. If you distribute the Internet only in this range, the client device simply will not detect the access point. Switch the access point setting to 2.4 GHz for maximum compatibility.
⚠️ Attention: The names of menu items and available frequency bands depend on the hardware of your smartphone. If the "Range" item is missing, it means that your device only works in one standard.
You can use developer mode to diagnose problems. By turning it on (tapping 7 times on the build number in About Phone), you will have access to advanced Wi-Fi statistics. There you can see the signal strength, connection speed and security protocol used in real time.
If your phone constantly loses the network, try disabling the “Scan always available” function in the Wi-Fi settings. This sometimes helps save battery power and stabilize the connection on older devices.
Frequently asked questions (FAQ)
Is it possible to find out the Wi-Fi password without connecting to a network?
No, using standard Android tools it is impossible to view the password from a network to which the phone has never been connected. Passwords are stored only for active or previously saved connections. For new networks, the key must be entered manually or scan the QR code from the router.
Why does the "Share" button not show the password text, but only the QR code?
This depends on the version of Android and the manufacturer's shell. In some versions (for example, pure Android 11), the password text is hidden under the QR code for security reasons. To see the symbols, sometimes you need to take a screenshot of the code and open it in the Google Lens app or gallery with OCR.
Is it safe to transfer a security key via a QR code?
Yes, it is safe for personal transfer. The QR code acts as a one-time access key. However, you should not publish screenshots with the code on the Internet, since anyone who scans the image will gain access to your network.
What should I do if I changed the password on the router, but the phone does not connect?
You need to “Forget network” on the phone. Go to Wi-Fi settings, click on the name of your network and select "Delete" or "Forget". After that, try to connect again by entering a new security key.
Where can I find the security key if I unlocked the Bootloader?
Unlocking the bootloader itself does not give access to Wi-Fi system files. You will still need root access (for example, through Magisk) to read the file wpa_supplicant.conf. Without superuser rights, the path to the file will remain closed even if the bootloader is unlocked.
