Load up the sign-in page for any of your Google accounts and you’ll notice a little notification at the bottom saying there’s a “New look for sign-in coming soon”, as can be seen in the image in this article. This is pretty cryptic, so a link to a help page is included, which in all honesty, doesn’t help much.
What we can get from the airy help page is that this new look will be coming “in the next few weeks”. In terms of what it actually brings, we know it will “have a cleaner, simpler look”, “make the sign-in process faster” and “be consistent across computers, phones and tablets”. The actual sign-in steps and the ability to securely log into any Google account will not change, however.
