Microsoft Entra | Update to default sign-in background for Work or School accounts [MC1108834]

Message ID: MC1108834

We’re updating the default background image on Microsoft Entra sign-in screens for Work or School accounts. This visual refresh is designed to reduce distractions, improve focus during sign-in, and align with Microsoft’s modern Fluent design language, creating a more consistent and trusted authentication experience across Microsoft services.

[When this will happen:]

General Availability (Worldwide, GCC, GCCH, and DoD): We will begin rolling out late September 2025 and expect to complete by early October 2025.

[How this will affect your organization:]

This is a visual-only interface update and does not impact sign-in functionality. The new background will appear only on screens where company branding is not configured or where users are directed to a default sign-in experience

Tenants without a custom background configured:

    • The new background will appear on all authentication screens.

    Tenants with a custom background configured:

    • No change will be seen where a tenant ID or domain hint is present in the URL.
    • The new background may appear when users access login.microsoftonline.com without a domain hint or custom URL.

    Entra External ID tenants: 

    • No changes will be applied.

    [What you need to do to prepare:]

    No action is required. The update will be applied automatically.

    We recommend updating internal documentation and notifying your help desk to reduce potential confusion.

    To change the default background, consider configuring a custom background image via company branding. If you have configured a custom background image in company branding for your tenant, there will be no change for your users.
