Prevent external users, such as portal or partner users, from viewing personal information in your user records. Now when you apply the Enhanced Personal Information Management setting, Salesforce blocks view access to 20 fields that are considered personal information. This setting is also more flexible than the Hide Personal Information setting. To implement this setting, in User Management Settings, add or remove the PersonalInfo compliance category for any field.
Where: This change applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions.
