Final answer:
The System Administrator Profile is the default profile with 'View Encrypted Fields' permission in Salesforce. Other profiles need explicit permission to view encrypted fields.
Step-by-step explanation:
The System Administrator Profile in Salesforce is the standard profile that has the "View Encrypted Fields" permission active by default. This profile has a broad set of permissions that allow for the most extensive access to the system, including the ability to view encrypted data. Other profiles such as Solution Manager Profile, Standard User Profile, and any custom profiles do not have this permission active by default; it must be granted explicitly by a user with the necessary permissions to manage profiles and field-level security.
