Login to the router page
If you go to Connections in your Android phone's settings and click on the Wi-Fi option, it will show you which Wi-Fi network your phone is connected to. If you open the settings next to the network name, the Manage router option appears. Clicking it will open the router page and ask you to log in. Then type the signature and password on the back of your router and the login web page will open. In it, if you click on the wireless section and scroll down, it will say Network Key. Same WiFi password.
Wi-Fi apps
Another option to know Wi-Fi password is Wi-Fi password key or Wi-Fi password recovery apps. There are many related apps on play store. If you open the app after installing any app, it will show you the company names of your WiFi router. Clicking on the name of your router will show you a web page related to it. After entering your router username and password, you can click on the Wi-Fi section to find out your router password.
QR code
After entering the phone settings, you need to click on the settings symbol next to the WiFi name. Then at the bottom of the screen you will see the QR code. You can share it with your friends and family. If they scan it, the Wi-Fi password will be known. Similarly, if you open any QR code scanning website and paste this code into your Wi-Fi QR code, the website will tell you the Wi-Fi password of your router.
with IP address
In this, you need to type the IP address 192.168.0.1 or 192.168.1.1 in the web browser of your phone. Then the web page of your router will open. In it, type the username and password behind your router and go to the wireless page and scroll down to see your network key. The same with your Wi-Fi password.
However, the above options only work on phones running Android 10 or higher. You need to root your device to see the WiFi password, even on phones running Android 9 or lower OS. The Wi-Fi network details saved on it are stored in the phone storage. You do not have permission to open that folder. If you root your device, open the Data>MISC>Wi-Fi>wpa supplicant.conf file in the folders and your network name (ssid) and password (psk) will appear.
