I have a simple FileMaker citation database that I created in FileMaker over ten years ago. Over the years, I have updated to newer versions of FM (now 16). I use the database for keeping track of citations, poetry, and articles for my research and writing (my version of EverNote before EverNote existed). Recently, after clearing certificates on my KeyChain, a login pops up prompting me for username and password, but I never had a login before. I have tried various permutations of usernames and passwords that I frequently use, but to no avail. Any suggestions about how to get back into my citations database or why a login is now suddenly required? I'm working on a MacBook. Thanks!
