A new installation requires that certain attributes be provisioned on the Spire server. These steps occur once, when installing a server for the first time.
Create a Spire Administrator Account and provision a security certificate. This user is required to create and manage Spire user accounts, and it used to access Spire Server Administration. Other Admin users can be created at a later time. There must be at least one admin user.
The next step will ask you to create a Spire administrator account. This user has full access to all companies and settings. Other administrators can be added later. If upgrading from a previous version, or importing from another system, an existing user can be used.
You will then be asked to retrieve your existing license or create a new one.

Next you enter your email address and password and click ‘Log In’ or create a trial license by clicking “Sign Up”. If you have a gmail account or your company email is hosted on Google, then select “LOG IN WITH GOOGLE”. Note that this is the email address associated with the Spire license holder.
An email will then be sent to the address entered on the above screen.
Retrieve the email and click on ‘Verify Your Account’
You will get a message that the email was verified.
Click on ‘login’
On a new installation or trial installation, fill in the company details and click save.
Next the security certificate will be retrieved or created. This can take several minutes.
You will then be be asked to log into the Spire Administrator account. Enter the Spire admin user ID and password created earlier.
