You register the base domain, and it is valid for any subdomain. So if you add to your profile, let's say:
mycompany.com

Any subdomain will be valid:
• www.mycompany.com
• dev.mycompany.com

Press save and a new certificate is generated. You can also add an IP to the authorised domains box and save your profile, and a new certificate is generated with the IP address. Localhost is already included.

Your license key is valid for one year and works offline. To keep using it, renew and replace it in your deployment after the year has elapsed. You can generate a new license key at any time through your profile, even before the current license expires.

2. Click on "Renew License."
3. Scroll down to the bottom of the page and click "Save."
