Yes they are all on the same system. All of them created end 2022 and earlier have the toggle. All created after 3-2023 do not. I have that same button in > Server administrator permissions > set yes.
I guess they decided it might be safer to take it out. If I find it I’ll post it.
That must be it. I just made a test server and the toggle is not there. About the time it quit showing I migrated to a new server and set it up with encrypted passwords.
This feature is still there, however if the passwords are set not to be stored in plain-text (default on the new installs) in System Settings ⇾ Server Templates: Edit Server Template / Administration user page, then the button to preview the password won’t be shown.
