The existing native mobile solution from Mendix keeps a user logged in if they close the app without signing out. Closing the app is achieved by swiping the app out from the background app carousel.
Now this poses a security risk for banking use cases since the standard behaviour is to log the user out whenever the app is closed.
For now we have implemented a workaround to detect app closure and sign the user out, but this workaround degrades performance. We would much prefer if Mendix directly catered for this scenario, perhaps by creating a configuration that gives customers a choice if they want this behaviour for their apps.
