I am using Filemaker Pro 14 and trying to open a file. Since yesterday it opened without problems, but since today a password is required which I never created. How can I access the file? It was created using version 12.
If you are using a Mac, perhaps keychain was using credentials to open the file for you and now keychain has been changed.
Also, all FileMaker files require credentials to open them. It's just that file options are set to open new files using the Admin account name and no password as credentials. So try Admin with no password to see if that opens the file for you.
"Admin" with empty password is the default full access account.
