Let me ask you about the concept of external user licenses.

Now, we have a project for a certification platform system that conducts online testing.

I'm considering adopting Outsystems for this project.

In this case, it is necessary to accept an unspecified number of users who want to take online exams.

Those users must be non-Anonimous users as they will need to log in as they will need to log in to view the test results and download the certificate.

I think it is correct to use an "external user license" to realize these users on Outsystem. Is this correct?

I had the opportunity to talk to Mendix sales, so I asked Mendix sales how to resolve this case and they got an answer.

He said that one user license could be used to manage logged-in users internally.

Is it a license violation on Outsystems?

Also, I would like to ask someone who has already realized a system that accepts an unspecified number of users, as in this case. Are you purchasing an external user license? In that case, the license cannot be reused unless the user unsubscribes, so we have to increase it endlessly. How do you solve this?
