Hi @sophieg10675163
Adobe ID - is created, owned, and managed by the end-user. Adobe performs the authentication and the end user manages the identity. Users retain complete control over files and data associated with their ID. Users can purchase additional products and services from Adobe. Admins invite users to join the organization and can remove them. However, users cannot be locked out from their Adobe ID accounts. And the accounts can't be deleted or taken over by the admin.
The following are a few requirements and scenarios, where Adobe IDs are recommended:
If you want to enable users to create, own, and manage their identities.
If you want to allow users to purchase or sign up for other Adobe products and services.
If users already have Adobe IDs, and associated data such as files, fonts, or settings.
In educational setups, where students can retain their Adobe ID after they graduate.
If you have contractors and freelancers who don't use your corporate email address.
So, once the user leaves the organization you can remove the user access to the Experience Cloud solutions but the user will be able to access his Adobe account via that Adobe ID.
For more information on different identity types, you can refer to the below documentation link.

Hope this helps.
