To set up SSO, first create an account with either a password or with a personal SSO provider (Google or Microsoft). This account will be the admin of the organisation in this application and can configure the Microsft Entra SSO on the subscriptions settings page.
If your organisation manages its users with Microsoft Entra ID, you can add OnePager Architect as an Enterprise application there. With this, you can manage which users of your tenant will have access to OnePager Architect.

By default, only users who are assigned to this application in Entra will be able to log in using the Enterprise Microsoft sign-in and their business Microsoft account, as long there are available licenses in your organization (no invitation needed!). You can revoke their access at any time from Microsoft Entra, however this will not free up their license until you remove them from the organisation in the OnePager App. To allow any user from your tenant to use this application, go to the Properties of the Enterprise Application, and change "Assignment required?" to "No".
