These concerns are both addressed (at least partially) by features of either iOS or FileMaker Go.
- It's possible to make a Home screen icon that launches a database in FileMaker Go by making a bookmark that launches a URL. You can make and distribute an iOS profile defining such a button. This tool can help.
- Look at the FileMaker Go Development Guide for documentation on the fmreauthenticate## extended privilege to address this issue.
You still may want to argue that doing either of these could be easier. For example, perhaps FileMaker Go could include a button to make a Home screen icon for a file, or FileMaker might implement a script step to make a Home screen icon.
Thanks. I will try to address both issues at the earliest opportunity following your recommedations.
