Your unique FTP user name and password should display in the FTP section of your Blackbaud.com profile. I do not have an FTP username or password on my profile.
Your unique FTP credentials should have automatically been created when you were added to our database with a valid email address. If they're missing, they likely weren't and we need to create them for you. Chat with Support and reference this article. In the meantime, if you need to transfer a file immediately, ask a co-worker to do so for you.
