WiFi Master Key gives you instant access to millions of wi-fi hotspots all over the world, all for free!

WiFi Master Key is an app that stores millions of user-verified wi-fi keys all in one place – you could literally land in any city on earth and find wi-fi access, that’s how good this app is.

It works like this: you open the app, you click “wi-fi key search”, and then available networks and keys are identified. The system stores geolocation, MAC device addresses, and other details so you don’t end up trying to access the wrong network in the wrong city with the wrong key.

Today WiFi Master Key boasts over 400,000,000 (yes, million!) known wi-fi networks that are constantly verified and updated by the community of millions of users like you. It’s available in 19 different languages and works in every country on earth, making it hands-down one of the best wi-fi key finder apps for Android.

It’s important to note that some users have issues with the app, specifically the “autoconnect” feature. The developer warns that if you experience this issue to avoid using autoconnect and instead manually connect using the “blue key” hotspot feature instead to fix.

Aside from some minor issues, the WiFi Master Key Android app is a great way to get connected on the go to over 400 million hotspots around the world.


  • Connect to over 400 Million Wi-Fi Hotspots New wi-fi hotspots are added every day, and keys are constantly checked and updated by users.
  • Simple and Easy to Use Works just like your built-in wi-fi scanner – just scan and connect!


  • Sometimes Autoconnect Doesn’t Work Support says to manually connect via the scanning option instead.

Potentially dangerous permissions

  • ACCESS_COARSE_LOCATION: Allows an app to access approximate location. Alternatively, you might want ACCESS_FINE_LOCATION.
  • ACCESS_FINE_LOCATION: Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.
  • CAMERA: Required to be able to access the camera device.
  • GET_ACCOUNTS: Allows access to the list of accounts in the Accounts Service.
  • READ_EXTERNAL_STORAGE: Allows an application to read from external storage.
  • READ_PHONE_STATE: Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
  • WRITE_EXTERNAL_STORAGE: Allows an application to write to external storage.

Other permissions

  • ACCESS_LOCATION_EXTRA_COMMANDS: Allows an application to access extra location provider commands.
  • ACCESS_NETWORK_STATE: Allows applications to access information about networks.
  • ACCESS_WIFI_STATE: Allows applications to access information about Wi-Fi networks.
  • BLUETOOTH: Allows applications to connect to paired bluetooth devices.
  • BLUETOOTH_ADMIN: Allows applications to discover and pair bluetooth devices.
  • BROADCAST_STICKY: Allows an application to broadcast sticky intents. These are broadcasts whose data is held by the system after being finished, so that clients can quickly retrieve that data without having to wait for the next broadcast.
  • CHANGE_NETWORK_STATE: Allows applications to change network connectivity state.
  • CHANGE_WIFI_STATE: Allows applications to change Wi-Fi connectivity state.
  • EXPAND_STATUS_BAR: Allows an application to expand or collapse the status bar.
  • INSTALL_SHORTCUT: Allows an application to install a shortcut in Launcher.
  • INTERNET: Allows applications to open network sockets.
  • READ_SYNC_SETTINGS: Allows applications to read the sync settings.
  • RECEIVE_BOOT_COMPLETED: Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
  • REQUEST_INSTALL_PACKAGES: Allows an application to request installing packages. Apps targeting APIs greater than 22 must hold this permission in order to use ACTION_INSTALL_PACKAGE.
  • SYSTEM_ALERT_WINDOW: Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.
  • WAKE_LOCK: Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.
  • WRITE_SETTINGS: Allows an application to read or write the system settings.
  • WRITE_SYNC_SETTINGS: Allows applications to write the sync settings.
  • android.permission.ACCESS_COARSE_UPDATES
  • android.permission.ACCESS_GPS
  • android.permission.AUTHENTICATE_ACCOUNTS
  • android.permission.FOREGROUND_SERVICE
  • android.permission.INTERACT_ACROSS_USERS
  • android.permission.READ_SETTINGS
  • android.permission.USE_CREDENTIALS
