Announcing A New Look For Your Microsoft Dynamics CRM Online Sign-in Experience
The new sign-in experience automatically adapts to the screen resolution and capabilities of different devices, operating systems and browsers. It looks best on recent versions of Internet Explorer (8+), Google Chrome, Safari, Windows Phones, iOS and Android devices. It is optimized for touch and also works great with mouse or keyboard-only navigation.

If you would like to preview the new interface prior to the rollout to your organization, please visit our opt-in page (note, this page is currently in English only). If you have additional questions, please visit Global Partner Services.
I hope this information is useful to partners.
Until next post!
