Provided name and password cannot be used to access file message Big Sur FM 19.3.2.206

Howdy FM19 Gurus,

I am a simple photographer who has been using Filemaker for my billing and database purposes since FM 7. I have tried a few times to use quickbooks or other apps, but they just don't do it for me.

The issue I am having, and maybe it is a simple one, is I am getting a message that says, "Provided name and password cannot be used to access file." I have my username already in the first field, and the password, or what I think was the password is not working. I have tried a number of different passwords too.

I have uninstalled and reinstalled FM19. So I don't think it is an issue with the FM program. I did recently update to Big Sur a few weeks ago, and can't remember if I have used FM since then. I think the problem is a keychain issue. I am at a loss. I have looked at my keychain access and did not see the login listed there. 

I use FM19 maybe an hour a week, and please forgive my ignorance. I just want back into my billing program that has all my clients info and my billing layout.

Thanks in advance,

Paul
