Many people asked me that how to use someone’s Wi-Fi password so that they can use free internet. There are many ways and software’s which promise to do the job for you but actually they all are total waste of time. Today I will tell you how you can find any Wi-Fi internet password using android app. Not so long ago you need to have a desktop computer with software which will do the job for you but technology has grown so much that you can do it just with your smartphone. Finding password of other peoples router is not a good thing to do and it’s illegal as well. So this method is described for education purposes only.

How to find wifi Password with Android

First of all you need rooted device(smartphone or tablet) with Broadcom bcm4329 or bcm4330 wireless chipset. Also Cyanogen ROM will be perfect for this project. Still if you are not sure about which device is perfect for this project here are the few names.

  • Nexus 7
  • Galaxy S1 to S7
  • Galaxy y
  • Nexus One
  • Desire HD

Download and Install BCMON

In order to find the wireless PIN you need to enable Monitor Mode on Broadcom chipset. For this you need BCmon APK file which you can download from link mention here.

Now it’s time to install this app but by default your Android device will not allow this installation so you have to enable installation from unknown sources in your phone security settings.

Run bcmon app and sometimes it will also you to install firmware and tools. Just enable the Monitor Mode and it should run stable on your device. If not than your device is not supported.

Run Bcmon Terminal

Now this is the most scary parts of this project because it will open a terminal or command prompt like Linux. Here you need to run few commands like airodump-ng and press enter button.

An application Airdump will load and you should go back to the main terminal again. Here again type airodump-ng wlan0 command and hit enter.

Choose Access Point/Router

Now it’s time for fun part because you are very near to your success. The only down side is that from all routers you will be only able to find WEP encryption access points so if you want to find WPA2 routers password than read second method mention below.

You will be able to see MAC address and channel along side all routers so write down it on paper. Now start scanning the channel for information. Remember it will take hours so relax and go get yourself a cup of coffee.

Start Scanning

You need to change the MAC address and Channel number with the one your wrote on paper before. Now keep scanning the router for at-least 30,000-40,000 packets.

Once you have sufficient amount of data it’s time to find the password. Run the command aircrak-ng output*.cap and press enter.

After you found a password for your desire network make sure that it’s probability is 100% in the app otherwise it may not work for you. Key will be in the form of Hexa Decimal like 75:03:17:24:74 and all you need to do is to remove the colon “:” in between this phrase and this is the desire password for you.
