Out-of-the-box, FME Flow has an admin login for administration (member of fmeadmin and fmesuperuser).
As a measure of added security, can a different, less common, login name be used for administration? In other words, if I were to create a login for administration purpose named MickeyMouse, add MickeyMouse to fmeadmin and fmesuperuser roles, and disable admin, does that work? Are there gotcha’s with doing that? Is it a measure of added security?
If you have a sufficiently strong password, it shouldn’t really be an issue.
You can create new accounts and assign them the same permissions as the admin account. You wont be able to disable the admin account when you’re logged in as it. So create the new account(s) then login as them and disable the admin account.
I always err on the side of caution and create two admin accounts during a setup, in case one of the passwords is lost/changed, then you still have administration access to the server.
