OpenWifiPass – An Open Source Implementation Of Apple’s Wi-Fi Password Sharing Protocol In Python

An open source implementation of the grantor role in Apple’s Wi-Fi Password Sharing protocol.


OpenWifiPass is experimental software and is the result of reverse engineering efforts by the Open Wireless Link project. The code serves solely documentary and educational purposes. It is untested and incomplete. For example, the code does not verify the identity of the requestor. So, do not use this implementation with sensitive Wi-Fi credentials. OpenWifiPass is not affiliated with or endorsed by Apple Inc.


Hardware: Bluetooth Low Energy radio, e.g., Raspberry Pi 4

OS: Linux (due to the bluepy dependency)


Clone this repository and install it:


Run openwifipass to share Wi-Fi credentials (SSID and PSK) with any requestor (we need super user privileges to use the Bluetooth subsystem):

sudo -E python3 -m openwifipass --ssid <SSID> --psk <PSK>

Use quoting of your shell to remove special meaning of certain characters in SSID/PSK. In the example below, we use single quotes (') to prevent shell expansion of the $ character in the PSK.

A successful run of the protocol would look as follows:

[email protected]:~/openwifipass $ sudo -E python3 -m openwifipass --ssid OWL --psk '$uper$ecretPassword'
Start scanning...
SSID match in PWS advertisement from aa:bb:cc:dd:ee:ff
Connect to device aa:bb:cc:dd:ee:ff
Send PWS1
Receive PWS2
Send M1
Receive M2
Send M3
Receive M4
Send PWS3
Receive PWS4
Wi-Fi Password Sharing completed
