The Mimecast Log In page has a clean, modern look and feel, with the fields displayed in the center of the page. This provides a consistent experience when accessing Mimecast on different sized devices. The design applies to all elements of Log In including resetting cloud password, using, and registering for 2FA.
If you access your Mimecast web application via a branded URL, your companies custom branding is applied to the Log In page (see an example below). You may wish to review your current branding set(s).
