In the settings tab you can configure your workspace.
To become a validator, the only setting you need is the mnemonic key inserted in the KEY MANAGEMENT section.
Important: make sure to save your mnemonic key! We'll repeat this many times in this guide because the key will be linked to your unique biometric data. If you lose the key, you will not be able to decrypt your biometric data anymore and will lose your ability to become a validator forever in the blockchain.
To insert the mnemonic key into your node start by pressing the Insert mnemonic button. You will be prompted with the following dialog where you can directly insert your mnemonic or generate it:
It is safer to generate the mnemonic using your wallet. This way you are less likely to loose access to it.
To generate a mnemonic, press the GENERATE button. A new dialog will pop up showing you the mnemonic.

Copy the mnemonic and save it somewhere safe. Once closing this dialog your clipboard will be erased. This is intentionally made so that you save your mnemonic somewhere.
Once you have saved your mnemonic somewhere safe, you can proceed to insert it by pressing the insert button:
Once a mnemonic is inserted in the workspace, it cannot be modified. If you want to change it, you must remove the workspace and reconfigure it from scratch.
You can additionally add a name to your node that will be publicly shared with the blockchain.
If you have a public URL associated with your machine, you can use that by setting the Public URL field.
When you connect to your node through the QR code described later, you are actually accessing it through a tunnel which allows your phone to properly establish a connection with your node through the networks. There are two types of tunnels available in the Humanode app:
Humanode WebSocket Tunnel: a tunnel provider built by the humanode team. This type of tunnel does not require any additional configuration.
ngrok: a tunnel provider available at https://ngrok.com. This type of tunnel requires additional configuration listed below.
ngrok is a free service that allows us to create a tunnel between your node and your mobile phone that you will use when scanning a QR code.
ngrok is not affiliated with Humanode
You need to create an ngrok account at ngrok.com and insert your authorization key to allow the Desktop App to create ngrok tunnels for you.
There is a chance that ngrok will "just work" without the key - but if it doesn't, you will have to create an account and provide your authorization key.
To insert an ngrok auth key, press Insert Authorization Key. That will open a modal window with an input field.
Copy and paste your auth key that can be found here.
Press Insert to save this key. The state of the section will not be changed since we can't detect if the key was inserted or not. However, rest assured that the key is there.
If you want to start ngrok from your terminal, put a tick in Manually start ngrok.
Updates section stands for checking the available peer updates. Most likely, if you just downloaded the app, you have the latest version, but in the future, make sure you regularly check for updates.
You'll see the next message if there is an available update. Please stop the node before you start.
Or no updates available:
You can start the node again when the updating process is finished:
This section contains destructive actions and has to be used carefully.
