The Adobe ID you use to sign in to the Folio Builder panel is tied to the Adobe ID (called the “Title ID”) you specify when creating the viewer app in DPS App Builder. This Adobe ID should be assigned an "Application" role using the Account Administration tool.
For example, suppose that you belong to a company called Sporty and you publish magazines about kayaking and cycling. For best results, create one Adobe ID called “firstname.lastname@example.org” and another called “email@example.com.”
When creating and publishing folios about kayaking, use the kayaking Adobe ID to sign in to the Folio Builder panel and Folio Producer. When creating the custom viewer app for kayaking, you specify the kayaking Adobe ID in the Title ID field in DPS App Builder. (The Adobe ID you use to sign in to the DPS App Builder may be a different Adobe ID, depending on the settings in the Account Administration tool.)
Similarly, for the cycling app, you would use the cycling Adobe ID to create and publish folios, and you would specify the cycling Adobe ID as the Title ID in DPS App Builder.
Folios you publish using the kayaking Adobe ID appear in the kayaking app. Folios you publish using the cycling Adobe ID appear in the cycling app.
