I’m excited to announce that a visual design update is coming to the Azure AD and Microsoft 365 sign-in experience in April. The freshened default background image on our sign-in screens will be one percent the size of the previous image—reducing bandwidth requirements and improving perceived page load times, especially on slower networks.
This is solely a visual user interface (UI) change with no changes to functionality and only affects screens where our default background image (screenshot on the left) shows up today. If you’ve configured a custom background image in Company Branding for your tenant there is no change to your users. However, if this change affects your users, we recommend updating any documentation that contains screenshots and to give your help desk a heads up.
We plan on rolling this out globally in the first week of April. We always love to hear your feedback and suggestions and look forward to hearing from you! Let us know what you think in the comments below.
