Hi Gregory (or Bruce?)
Can you advise if the file has an auto-login set in the File Options? You will need to check this in FileMaker Pro as it cannot be set or changed in FileMaker Go.
If you turn OFF the "Auto-Restore Login" setting in FileMaker Go, you should be prompted whether you want to continue where you left off with the databases that were open when you last quit. If you say Yes, the databases may open without asking for account credentials depending on how they were previously logged in.
