• Do you have a company domain? (company.com)
• Are you using active directory to log in your users?
• Would you like to use your company username and password to log in automatically?
• Is your IT department able to help you set up your subscription?

 If you answered yes to all these questions, then you should set up an SSO subscription.

• This will require the help of your IT department (Azure AD global admin rights required).
• The IT department will need to authorize each of the company domains that your users could log in from (company.com, company.org, company.co.uk) etc…
• Nialli will need to map each of these domains to your subscription.

If you answered NO to any of these questions, then you should set up a non-SSO subscription.

• Each user will need a Microsoft Account to sign in. 
• Somebody in your company will have to be responsible for adding all of the individual users to your subscription in the non-SSO user table.
