If you already have a valid security profile created, you can reuse that profile and skip creating and configuring a new security profile.

Create a Login with Amazon Security Profile

To facilitate account linking in the Smart Home sample code, a security profile is needed to generate a Client ID and Client Secret to use during the configuration of the Alexa skill.

In your web browser, go to https://developer.amazon.com/lwa/sp/overview.html.
On the Login with Amazon page, click the Create a New Security Profile.
On the Security Profile Management page, enter Smart Home Security Profile Mischianti for the Security Profile Name.
For the Security Profile Description enter A Security profile for Mischianti Alexa Smart Home Skill.
For the Consent Privacy Notice URL/URL del consenso all’Informativa sulla privacy enter https://mischianti.org/privacy-policy-2/ for illustrative purposes or use your own if you already have a public consent privacy policy. For a production Smart Home Skill, a valid consent privacy notice will be required.
For the Consent Logo Image use the alexa-mischianti-smarthome-150x file in the /resources source folder or download to your working directory and then click the Upload Image area to load the PNG file from where you saved it.
If your profile configuration looks like the following, click Save on the Security Profile Management page.

Configure the Login with Amazon Security Profile

Copy the displayed Client ID and Client Secret values and save them to the setup.txt file in the alexa-skill-manage-relay directory replacing the format example entries for [Login with Amazon Client ID] and [Login with Amazon Client Secret] respectively.
