Having the same issue with our folks without articulate IDs!
There are a few reasons why someone might be being prompted to login, and all of it leads to them having an Articulate ID. Keep in mind that an Articulate ID does not necessarily mean they have a subscription to Articulate 360. It just means at some point, for some reason, they've been in the Articulate ecosystem. This could be because they were once a reviewer on a project that did NOT allow users w/o Articulate IDs to comment, and so they had to create an account, or it could be that they took a trial at some point or had a previous subscription. For those people who are being prompted to login, just have them go through the "forgot password" process on the login page, and they should be good to go.
