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.

To experience this enhancement, you will not need to take any action. You will notice this update beginning in March 2013. 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!
