Which role can you give access rights to in order for them to apply to all accounts in Sitecore?

Assigning access rights to "Everyone" ensures that the permissions apply universally to all user accounts within Sitecore. This is particularly useful for setting base-level access or for features or content that should be available to all users, regardless of their specific roles.

When "Everyone" is selected, it effectively means that any user who can log into Sitecore will inherit the permissions granted, which can be essential for widespread access to certain features or content. This choice is strategic when wanting to establish default access settings that don't require individually assigning permissions to numerous different user accounts or roles.

The other roles have more specific implications. For instance, "Authenticated Users" provides access to users who have logged into the system but does not encompass users who might not have credentials. "Administrators" and "Content Authors" represent more defined roles with potentially higher privileges, thereby making them impractical for blanket access settings across all accounts.
