# DigitalDNA key configurations and management

This page will help you understand how to configure and manage a DigitalDNA key, starting from the pairing and then looking all the possible settings.

## Pairing

To pair a DigitalDNA key, you can use the dedicated widget in the homepage and tap on "Set up DigitalDNA key".

Homepage
This same operation can be started from the "Certificate and Devices" section, available opening the top-right menu.

Certificates and Devices
In case you have not already configured any certificate, just select the "Add Device Certificate" option.

Certificates and devices - nothing is configured
Otherwise, select "Add certificate" first and then "Add Device Certificate".

Certificates and devices - remote signature configured
After this first step, Namirial Sign will start a Bluetooth research to look for any DigitalDNA present nearby.

It is important that:

- The Bluetooth of the smartphone is enabled.
- The Bluetooth of the DigitalDNA key is set to on (there is a specific slider on the side, the blue led in the middle should blink).
- You have granted the permission to Namirial Sign for looking for nearby devices.


Pairing research
Once your device has been identified, select it (look at the number on the backs of your DigitalDNA key). To start the pairing, you will be asked to press and hold the botton on the front of the DigitalDNA key until the blue led blinks faster.

Pairing - hold the button of the DigitalDNA key
Then, type the device PIN.

Pairing - waiting for PIN
Here, if you have enabled the biometric authentication on your smartphone, you will have the possibility to choose whether to save the PIN by using the Touch ID / Face ID (according to the device), so that, when signing, you will be no longer requested to enter it.
You can choose to use both the PIN and the biometrics when signing too.

After these simple steps, the pairing is completed and you will notice a change in the homepage, where you can easly identify the DigitalDNA key in the corresponding widget.

Mind that you can pair only one DigitalDNA key at a time, so, in case you have to use a different one, you will need to perform an unpairing first.

## Certificates

Too see the certificates, you can go to "Certificates and devices" in the top-right menu. There, your DigitalDNA key will be identified with the corresponding icon.
