Customise Joomla’s Atum login screen without changing the backend

The job is to brand and restyle the administrator login page before a user signs in.

This comes up when a client portal, agency-managed site or multi-site installation needs a recognisable entry screen rather than Joomla’s standard administrator presentation. Joomla core already provides the Atum administrator template and its template-style controls, and developers can use CSS or a template override when they are prepared to maintain code. Those approaches are broader or more manual: changing Atum can affect the administrator interface beyond the login page, while an override has to be maintained through template changes. According to the listing, this free system plugin instead provides login-specific controls for the logo, background, login card, header, footer and selected layout elements, plus JSON settings import/export and custom CSS and JavaScript. Its stated scope is the pre-authentication screen, not the working back end.

It is aimed at agencies, organisations and site owners that want branded or client-specific administrator access screens across more than one Joomla site. A normal content site using the default administrator login, or a team happy to edit a template override, has little reason to add it.

The listing identifies FG Admin Login Customizer as a free download from ferino in the Admin styling section, licensed under GPLv2 or later, and lists Joomla 6 compatibility. The directory shows five other extensions from the developer, but this entry has no reviews and says support is not available. Before installing, check whether the stated Joomla 6 support matches the target site, how custom JavaScript and footer HTML are handled, whether imported settings are validated, and what happens to customisations after updates. The listing does not provide those details.
