Microsoft is transforming its Microsoft Account (MSA) sign-in experience to create a modern interface across web and mobile platforms, with plans for Windows to follow. By the end of April, users will see a revamped login and registration process with a streamlined flow and fewer elements per screen. The update will optimize passwordless sign-ins through the introduction of passkeys, which will become the default method for future logins. If a passkey is not used, email-based logins will be the fallback option. The redesigned interface will feature consistent Microsoft branding, with a unified background image and color-themed buttons and links for different services. The rollout of this new experience is expected to be completed by the end of April.
