Customize a Modern Theme
Use Modern Themes to apply your organization’s branding, such as logos, colors, and languages, to supported internal application pages.
Modern Themes apply only to Identity Management (IdM) pages in the New Experience, such as the SSO Portal and User Account pages. You can toggle on the Modernized Layout setting in the Internal Application Manager and attach a Modern Theme.
Note
Modern Themes do not apply to pre-authentication login pages or MFA pages. Those use the default theme selected in Advanced Settings > Overview tab, which is based on preset platform-wide UI options.
