Set dashboards as home for all users
While it is possible for individual users to set dashboards, rather than homepages, you can also set dashboards as home for all users. By default, the most recent dashboard a user has visited is the dashboard they see when they log in to ServiceNow.
Before you begin
The functionality found in homepages, arranging information from your instance to tell a story about your data, is found in dashboards on new instances. On upgraded instances with Next Experience enabled, users can view existing homepages if they have a direct URL, but they can't create or edit them. Responsive dashboards and Analytics Center dashboards take over homepage functionality.
Use the Homepage deprecation help tool to convert the homepages on your instance to responsive dashboards.
