This blog announces the general availability of the enhanced company branding functionality that allows for customization of the Microsoft Entra ID and Microsoft 365 sign-in experience with less effort.
The experience controls apply to sign-in for users in the directory and for external users, including use cases for B2B, B2E, Customer Identity and Access Management (CIAM) and first-party applications running on Entra ID. With enhanced company branding, you’ll be able to create a custom look and feel for the default sign in pages, as well as pages targeting specific browser languages. In addition, you can now customize self-service password reset (SSPR), footer hyperlinks, and browser icon, style sign-in experiences using cascading style sheets (CSS) and enable header and footer using one of the pre-defined templates.
