Once you’ve written the image file onto the SD card, there’re a few steps you’ll have to follow in order to configure your new Pwnagotchi properly.
PLEASE NOTE:As we migraded from yaml to toml as our configuration language, you probably want to have a look at the toml reference. If you update from an old pwnagotchi version, your old configuration will be loaded and automatically saved in the new toml format. The old configuration won't be deleted, but not be used anymore. In the future yaml-support will be completly dropped.
For the initial configuration, the easiest way is creating a new
config.toml file of the
boot partition of the SD card.
This partition should be easily accessible from your computer regardless of your operating system as it is a simple FAT32.
In this process you might define your unit’s name, which network to whitelist and the type of display you use. The following is the example configuration for a unit with a Waveshare V2 display, for more detailed configuration instructions refer to the sections below.
main.name = "pwnagotchi" main.lang = "en" main.whitelist = [ "EXAMPLE_NETWORK", "ANOTHER_EXAMPLE_NETWORK", "fo:od:ba:be:fo:od", "fo:od:ba" ] main.plugins.grid.enabled = true main.plugins.grid.report = true main.plugins.grid.exclude = [ "YourHomeNetworkHere" ] ui.display.enabled = true ui.display.type = "waveshare_2" ui.display.color = "black"
The software will install this file to
/etc/pwnagotchi/config.toml (and it will remove it from the SD card) during boot.
After the first boot, you can open the
/etc/pwnagotchi/config.toml file (either via SSH or by directly editing the SD card’s contents from a computer with a card reader) to override the default configuration with your custom values.
If you want to restore a backup instead, you can copy the contents of the
/etc/pwnagotchi backupped folder in the FAT32 boot partition as
This way the whole folder containing the configuration and the RSA keypair will be moved to
/etc/pwnagotchi during boot. Restoring this folder this way will allow the unit to boot without the need to generate a new RSA keypair, an operation that takes time and would be completely pointless if a backup needs to be restored anyway.
Given that the FAT32 boot partition is limited in size, other folders and files that are part of the backup will need to be copied manually either to the SD card, if it’s possible to mount it on a host computer, or via SSH with cable or bluetooth connectivity as explained in the following sections.
Pwnagotchi displays it’s UI in English by default, but it can speak several other languages! If you’re fine with English, you don’t need to do anything special here.
But if you do want to change what language Pwnagotchi displays its status in, you can change
main.lang to one of the supported languages:
If you want to contribute a new language (or improve an existing translation!), you can check out the Adding a Language doc for more details.
By default, the
grid plugin is only partially enabled. This means that whenever the unit will detect internet connectivity while in MANUAL mode, it will signal its existence to the PwnGrid server by sending ONLY the following enrollment data:
uname -acommand on the unit used to determine the type of hardware.
If you would like your unit to participate in PwnGrid’s community rankings and scoreboards (PwnGrid is like Pokémon Go, but for WiFi!), as well as be a data point in regional (country-level) statistics, you can fully opt-in to PwnGrid by enabling your unit to send the PwnGrid API some basic information about the networks it has pwned. None of your unit’s captured cryptographic material is sent to the PwnGrid server; ONLY the minimum information to enroll the unit in the PwnGrid database (see above) and calculate how many networks it has “conquered” so far, namely:
In order to fully opt-in to PwnGrid, you must make the following change in your
main.plugins.grid.enabled = true main.plugins.grid.report = true # full-opt in
Even if you have decided to fully opted-in to PwnGrid, you can still disable reporting for specific networks—for instance, if you don’t want your home network to be in the system:
main.plugins.grid.enabled = true main.plugins.grid.report = true # full-opt in main.plugins.grid.exclude = [ "YourHomeNetworkHere", # both ESSIDs and BSSIDs are supported "de:ad:be:ef:de:ad" # both ESSIDs and BSSIDs are supported ]
If instead you prefer to completely opt-out by also disabling signaling:
main.plugins.grid.enabled = false main.plugins.grid.report = false
If you want to use the web UI (instead of an e-ink display attached to your unit's RPi0W) to see your Pwnagotchi's face, check out the User Interface doc for more details on using the web UI.
Set the type of display you want to use via
If your display does not work after changing this setting, you might need to completely remove power from the Raspberry Pi and make a clean boot.

You can configure the refresh interval of the display via
ui.fps. We recommend using a slow refresh rate to avoid shortening the lifetime of your e-ink display. The default value is
0, which will only refresh when changes are made to the screen.
config.toml file in the
boot partition of the SD card should now look something like the following (with the
right differences if you’re using different hardware):
main.name = "pwnagotchi" main.whitelist = [ "YourHomeNetworkMaybe" ] main.plugins.grid.enabled = true main.plugins.grid.report = true main.plugins.grid.exclude = [ "YourHomeNetworkMaybe" ] ui.display.type = "inky" ui.display.color = "black"
Congratulations! Your SD card is now ready for the first boot! 👾 🎉
You can connect to your Pwnagotchi via SSH.
PLEASE NOTE: If you cannot connect to your Pwnagotchi no matter what you try, ensure that the micro-USB you are using allows data transfer and doesn't ONLY provide charge. Cheaper quality micro-USB cords often do not support data transfer and will NOT allow you to actually connect to your Pwnagotchi. :'( Use a quality cord!
pwnagotchi.localwon’t work. Instead, try your unit’s hostname +

DEV NOTE: These are directions for the recommended hardware, a Pi0w - and connecting to it from a Linux based host via a Micro-USB through the data port. This was written while connecting to a Pi0w with a Data Capable MicroUSB to a Macbook Pro late 2012 running Ubuntu 19.04. It will also work on Lenovo's running Ubuntu 19.04 and 19.10. We can not guarantee these specific directions work on any other OS.

TIP: you may need to use the `linux_connection_share.sh` script before your PC will allow you to ssh to your Pi. [Host connection sharing](/configuration/#host-connection-sharing)
DEV NOTE: if you have some issues, either you are using the wrong cord, or your Operating System is missing required drivers, or something mostly out of our control. We can't help everyone with their networking, sorry
The default password is
raspberry; you should change it as soon as you log in for the first time by issuing the
passwd command and selecting a new and more complex passphrase.
If you want to login directly without entering a password (recommended and necessary for certain packaged scripts to work, like
backup.sh for instance!), copy your SSH public key to the unit’s authorized keys:
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]

Make sure to explicitly enable Bluetooth Tethering on your Phone (usually in Settings -> Hotspot or similar) before pairing. Otherwise your Pwnagotchi will pair with your phone but you won't be able to create a Personal Area Network (PAN) even if you enable it after.
Now in pwnagotchi’s
config.toml add the following:

E.g. this is #1 main.plugins.bt-tether.devices.android-phone.mac = "" # you need to put your phones ## bt-mac here (settings > status) main.plugins.bt-tether.devices.android-phone.ip = "192.168.44.44" # this is the static ip of your pwnagotchi ## adjust this to your phones pan-network ## (run "ifconfig bt-pan" on your phone) ## if you feel lucky, ## try: 192.168.44.44 (Android) or ## 172.20.10.6 (iOS) ## 44 is just an example, you can choose ## between 2-254 (if netmask is 24) main.plugins.bt-tether.devices.android-phone.netmask = 24 # netmask of the PAN main.plugins.bt-tether.devices.android-phone.interval = 1 # in minues, how often should ## the device be searched main.plugins.bt-tether.devices.android-phone.scantime = 10 # in seconds, how long should be searched ## on each interval main.plugins.bt-tether.devices.android-phone.max_tries = 10 # how many times it should try to find the ## phone (0 = endless) main.plugins.bt-tether.devices.android-phone.share_internet = false # set to true if you want to have ## internet via bluetooth main.plugins.bt-tether.devices.android-phone.priority = 1 # the device with the highest ## priority wins (1 = highest) main.plugins.bt-tether.devices.ios-phone.enabled = false # next device... main.plugins.bt-tether.devices.ios-phone.search_order = 2
The legacy configuration (without the `devices` key) is still supported, but should be converted as soon as possible.
Your pwnagotchi will indicate the status via a little
BT symbol at the top of the screen.
The status codes are:
If you want to fix these problems, the first step should be to start pwnagotchi with
check the log file (
/var/log/pwnagotchi.log) for related debug messages.
Some users had problems with the auto pairing feature of the plugin (in old versions). If your pwnagotchi should not make an effort to connect to your bluetooth device after a few minutes, there is a chance that this can be fixed by doing the pairing manually. To do this, put your phone in discoverable mode. On your pwnagotchi, run
sudo bluetoothctl and once in the bluetooth-shell, type
scan on. That will scan the environment for nearby bluetooth devices.
Pick the mac of your phone and type
pair <mac> and
trust <mac>. In short time (maybe not immediately)
you will be prompted on the phone to allow connection from your pwnagotchi hostname.
As you may know, sdcards have a limited count of write cycles and can break from time to time. A good way to prevent this is to minimize the writes to sdcard. Pwnagotchi has the ability to mount certain directories into memory and only write it back to the sdcard after a certain interval. To activate this functionality, you have to change your config to:
fs.memory.enabled = true fs.memory.mounts.log.enabled = true fs.memory.mounts.data.enabled = true
The full configuration of a mount looks like this:
fs.memory.mounts.log.enabled = true # switch fs.memory.mounts.log.mount = "/var/log" # which directory to map into memory fs.memory.mounts.log.size = "50M" # max size to put into memory fs.memory.mounts.log.sync = 60 # interval in seconds to sync back onto disk fs.memory.mounts.log.zram = true # use zram for compression (recommended) fs.memory.mounts.log.rsync = true # use rsync to copy only the difference (recommended)
Shit happenz. What if you loose your pwnagotchi? All your data, configuration incl. api-keys, are lost. To prevent the leak of your sensible data, it’s a good idea to encrypt your data.
To do this, we can make use of the dm-crypt subsystem of linux.
Pwnagotchi will look for the file /root/.pwnagotchi-crypted. Every line in this file represents a luks-container that will be decrypted and mounted before pwnagotchi starts.
Each line must be in the following format:
$name $container_path $mountpoint
config /cryptobox1 /etc/pwnagotchi # /cryptobox1 is some file handshakes /dev/sdb /root/handshakes # /dev/sdb is some external storage
Don't use comments in this file.
But how does pwnagotchi decrypts it?
The following will happen do make it possible:
Let’s do this together! やりましょう！
# create a container file dd if=/dev/zero of=/cryptobox bs=1M count=100 # make it luks-ready! You'll be asked for a password. Remember it, # because you will have to type it everytime you start your pwnagotchi. cryptsetup luksFormat /cryptobox # Now we can open it (you'll have to type your password in) cryptsetup luksOpen /cryptobox cryptobox # create a ext4 filesystem mkfs.ext4 /dev/mapper/cryptobox # mount it to /mnt mount /dev/mapper/cryptobox /mnt # now we copy all the configs to /mnt/ cp /etc/pwnagotchi/* /mnt/ # remove the old files rm /etc/pwnagotchi/* # tell pwnagotchi about the encrypted container echo "cryptobox /cryptobox /etc/pwnagotchi" > /root/.pwnagotchi-crypted
All done configuring your new Pwnagotchi? Time to learn how to take care of your new friend over in Usage!
If your network connection keeps flapping on your device connecting to your Pwnagotchi:
* Check if
usb0 (or equivalent) device is being controlled by NetworkManager.
* You can check this via
nmcli dev status.
* If you are having trouble connecting to your Pi via USB, be sure you are using a microUSB cord that is capable of data transfer
