What happens if a user in Qlik Sense is not assigned a valid access level?

In Qlik Sense, user access levels dictate the permissions a user has regarding the applications and data within the environment. If a user is not assigned a valid access level, they truly cannot open the app. This restriction is in place to ensure that only authorized users can access the app and its associated data, safeguarding sensitive information and maintaining data integrity.

Not having a valid access level implies that their permissions have not been correctly defined, which can prevent access altogether. This is crucial for maintaining secure environments where access must be carefully managed. On the other hand, having limited data access or being assigned admin privileges would imply there is already a certain level of access established, which contradicts the scenario of having no valid access level assigned. Default permissions may apply in some contexts, but in the absence of a valid access assignment, the user simply cannot access the app.
