How are user accounts managed in Adobe Express?

User accounts in Adobe Express are primarily managed by linking to an Adobe ID for customization. This approach allows users to have a centralized identity that provides access to various Adobe services and tools, including personalized settings, project storage, and shared resources across different devices. By using an Adobe ID, users can easily navigate within Adobe's ecosystem, ensuring that their preferences and assets are synchronized, leading to a more cohesive user experience.

Linking to an Adobe ID also facilitates collaboration and sharing features, enabling users to work together on projects more efficiently. It also supports accessing other Adobe applications, making it easier for users who utilize multiple Adobe products to maintain continuity in their work.

The other options do not accurately represent how user accounts are managed within Adobe Express. Creating multiple accounts can lead to confusion and is not a streamlined practice for managing projects. Restricting access to certain features is typically a method to manage permissions, rather than a core aspect of user account management. Lastly, relying solely on third-party authentication can limit the integration and functionality that comes with using an Adobe ID, especially when it comes to accessing Adobe's full range of features and services.
