You don’t need to add the new Flywheel account to the Org. I’d suggest heading to this link – https://app.getflywheel.com/signup Then create an account using whatever email address you have available that you don’t use (say, spam email address). Then when you want to give Sucuri support access to the site via SFTP, simply add the new Flywheel account to the site and give them that account login instead.
What email address do you think we should use to create a sucuri account? This way we will not have to keep changing our user pw.
Could we create a group for email@example.com
