Microsoft is releasing a new default background image for Microsoft Entra and consumer authentication flows. No action is required of users or admins.
Authentication is often the first touchpoint users have with their organization, and it sets the tone for everything that follows. To align with modern design principles and meet evolving user expectations, we’re reimagining the Microsoft Entra sign-in experience with a user- and customer-driven lens, starting with a refreshed default background for all Microsoft authentication screens. This change is a visible result of our modernization journey for Microsoft Entra and a steppingstone to broader consistency across the personal and Microsoft Entra authentication experiences.
Megna Kokkalera, Product Manager leading the Microsoft Entra authentication UX modernization effort, will highlight the change for Microsoft Entra customers and talk about what’s next. Mike Scari, Principal Product Manager overseeing the authentication experiences platform, will outline the changes on the consumer side.
A new default sign-in background for Microsoft authentication
A new background image for sign-in screens will appear starting August 2025 for Microsoft personal accounts, and September 29, 2025, for Microsoft Entra work or school accounts. Aligning with broader efforts to modernize our end-user UX via Microsoft’s Fluent design language, this update aims to provide a cleaner, distraction-free experience and ensure consistent visuals across all authentication flows. When our experiences look and feel consistent, it gives all users a familiar experience that they know and trust.

No action required: Visual update only
This update is visual-only and does not affect sign-in functionality or require any action from users or administrators. It will be applied automatically across Microsoft Entra tenants and Microsoft Account (aka. Personal) sign-in pages. Company branding will still override the default background for Microsoft Entra work or school tenants. Microsoft Entra External ID tenants are not affected by this change.
This change will also be visible on certain Microsoft apps or portal sign-in screens, such as entra.microsoft.com or portal.azure.com.

Dark Mode support for personal Microsoft account UX
Personal Microsoft account users will see the new background beginning in August 2025. A full dark mode sign-in experience will be available soon after, depending on device and browser settings.
