Due to heightened security measures, the passwords are now "wired" to the WFA server.
On the other hand, there's no feature for resetting the admin password (We are discussing the particulars of one for an upcoming release. Not trivial, as you need to ascertain that feature is not accessible to non-admins).
What can be done is that we can manually handle it, providing you have made a previous backup. We can do without, but that would require us to connect to the machine with your assistance.
