Recently, while visiting a friend's place, I felt the need to connect to the Internet and ask the password to his home Wi-Fi. The perplexed look on the face of the friend's face was a telltale story and I had to rely on the data connection which my smartphone had. Considering that the Wi-Fi password happens to be a long string of alphabets and numerals for most Wi-Fi routers, it is is safe to assume that most of us do not remember it. If you also cannot remember your Wi-Fi password there is an easy method to know the same on your Android smartphone. However, we would like to inform you that this method only works on rooted Android smartphones and in case you do not have root, it will not be possible to know the password. When you connect to a Wi-Fi network on your smartphone, it saves the password on a file that can be accessed using a root explorer. If your smartphone is rooted and you have a root explorer installed in it, follow the steps mentioned below.
1. Open up the root explorer in your smartphone
2. Navigate to the Data folder
3. Tap on the Misc folder
4. Open Wi-Fi folder
5. Locate the wpa_supplicant.conf file and tap on it , select RB Text Editor from pop-up
6. Look for the SSID that is the name of your Wi-Fi and the password will be noted right below under PSK heading
However, if you cannot see the required information on your smartphone with above mentioned methods, then there is no other method to do so on the smartphone.
