It's quite common for smartphone owners to need to connect a new device to a wireless network, but the access key has long been forgotten or lost. Samsung Galaxy A8 (2018 models running Android 8.0 Oreo and later) find themselves in this situation just as often as users of other gadgets. Fortunately, modern versions of mobile operating systems make it easy to retrieve saved network data without resetting the router or performing complex programming.
The process of data recovery directly depends on the version Androidinstalled on your device, as interfaces and security policies have changed with each major update. Below, we'll detail all available methods, from standard system tools to specialized utilities, to gain access to configurations networks.
It's important to understand that you can only view the password if your smartphone has previously successfully connected to this access point and saved the data to its memory. If you've never entered the code on this device, you won't be able to recover it using standard methods, and you'll have to look for the data on the router itself or from your provider.
Using the QR code feature on Android 10 and later
Starting with the tenth version of the operating system, Google has introduced a convenient QR code generation function for quickly connecting guests. On smartphones Samsung with shell One UI This tool works stably and is the safest way to view saved data.
First, you need to go to the settings menu. Open Settings → Connections → Wi-FiHere you'll see a list of available networks, and at the top is the network you're currently connected to. Click the gear icon next to the active network or select the desired network from the list of saved networks (if this option is available in your firmware version).
⚠️ Attention: The QR code feature may not be available on some custom Android builds or on devices where the manufacturer has blocked this feature. In this case, proceed to the next section of the instructions.
After entering the network properties, a QR code will appear on the screen. Below it, in small print, is usually the text: "Scan the QR code to connect the device." In some versions Samsung One UI The password is displayed directly below the QR code in plain text. If there is no text, take a screenshot or use a second device with a camera and QR code recognition.
By scanning the code with the built-in scanner or through Google Lens, you will get a line like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword123;;The required access code is located after the symbol P: and before the two periods at the end of the line. This is your key.
Restoring access to Android 8 and 9 (Samsung Galaxy A8 2018)
Model Samsung Galaxy A8, released in 2018, initially shipped with Android 8.0 and was subsequently updated to Android 9.0. In these interface versions, the standard feature for viewing passwords via QR code was often missing or hidden deep within system menus.
If the standard method doesn't work, owners have to resort to more technical solutions. One way is to use the "Backup and Restore" feature or specialized applications that require certain access rights. However, the most reliable method for these versions remains obtaining root rights (superuser rights).
Obtaining administrator rights (Root) allows you to read system files that store all wireless connection settings. Without these rights, access to the file wpa_supplicant.conf Closed to regular applications for security reasons.
☑️ Check before rooting
Once you have root access, you will need a file manager with Root support, such as Root Explorer or ES File Explorer. Follow the path /data/misc/wifi/. You will find the file here. wpa_supplicant.conf. Open it as a text file.
Inside the file, you'll see configuration blocks for each saved network. Look for the line ssid="Your_Network_Name" and a line below it psk="your_password"The value in quotation marks after psk is the key we're looking for.
⚠️ Attention: Obtaining root access will void the device's warranty and may cause banking applications (Samsung Pay, Google Pay) to not function correctly, as the integrity of the security system is compromised. Knox.
Using third-party recovery applications
If you don't want to interfere with your smartphone's system or gain administrator rights, you can try using specialized software from Google PlayThere are many apps that market themselves as "Wi-Fi password recovery" apps.
However, it's important to understand how they work. On non-rooted devices, they can't crack the password or extract it directly from the system storage. Such programs typically work by exchanging databases or attempting to connect to the router through standard ports unless the router's factory security settings have been changed.
Popular utilities include:
- 📱 WiFi Password Viewer - requires root access to display saved keys in a convenient list.
- 📱 WiFi Map — uses crowdsourcing (a database of passwords uploaded by users), which can be helpful if the network is popular.
- 📱 Router Passwords — contains a database of standard passwords for thousands of router models, useful if the router has not been reconfigured.
The effectiveness of such programs on Samsung A8 Without root access, the security is extremely low. If your network is protected by a complex password you created yourself, a third-party app without deep system access won't be able to access it.
Why do apps require Root?
Password viewer apps require root access because Android stores security keys in a protected system directory /data/misc/wifi/, which is not accessible to regular apps to prevent data theft by malware.
Logging into the router's web interface via a smartphone
If your smartphone is connected to a WiFi network (even if you don't remember the password), it has an IP address and can communicate with the router. This allows you to access the router's control panel directly from your phone. Samsung and view or change your wireless network settings.
To do this, open any browser (Chrome, Samsung Internet) and enter the gateway IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1You can find the exact address in your phone's WiFi settings: tap the gear next to the network name and find the "Gateway" or "Router" field.
After entering the address, the system will ask for the administrator username and password. If you haven't changed them, try the default combinations:
- 🔑 Login:
admin, Password:admin - 🔑 Login:
admin, Password:password - 🔑 Login:
admin, Password: (empty field) - 🔑 Login:
user, Password:user
Once in the router menu (interfaces TP-Link, ASUS, D-Link, Zyxel look different, but the logic is the same), find the section Wireless or "Wireless Network." The current password will be displayed in the "Password," "PSK Key," or "Security Key" field. You can copy it or replace it with a new one.
⚠️ Attention: Router interfaces are constantly being updated. The menu items may be located differently than described. Look for tabs labeled "Wireless," "WLAN," "Wi-Fi," or "Security."
Table: Comparison of password recovery methods
To help you choose the best solution, we've organized the methods in the table below. This will help you quickly assess the risks and requirements for each option on your device. Samsung Galaxy A8.
| Method | Root is required | Complexity | Security |
|---|---|---|---|
| QR code (Android 10+) | No | Low | High |
| wpa_supplicant.conf file | Yes | High | Average (system risk) |
| Login to the router (browser) | No | Average | High |
| Third-party applications | Often yes | Low | Low (risk of viruses) |
As the table shows, the most secure and simple method is using a QR code, if the software version supports it. Logging into the router is also secure on a smartphone, but requires knowledge of the router administrator's credentials.
Resetting the router as a last resort
If none of the software methods help, the passwords are not saved, and you cannot log into the router (the administrator login/password is lost), the last radical option is to completely reset the router to factory settings.
To do this, find a small hole with the inscription on the router body. Reset or RestorePress it with a thin object (a paperclip or a needle) and hold it there for 10-15 seconds until the indicators blink. After rebooting, the router will have the default settings indicated on the sticker on the bottom of the case.
After the reset, you'll need to reconfigure your internet connection (enter your provider details) and set a new WiFi password. This method is guaranteed to resolve the access issue, but it will require time to reconfigure your entire home network.
⚠️ Attention: Before resetting your router, make sure you have a contract with your provider or the necessary PPPoE/L2TP settings. Otherwise, your internet may stop working even after your WiFi connection is restored.
