Set up your own libraries of values outside of the defaults provided by Data Mask to replace your personally identifiable information (PII). After you install the Data Mask managed package, your custom libraries can contain any string value, including digits, special characters, and non-English alphabets. The new Custom Library feature is now shipped with the managed package and is automatically updated when the managed package is upgraded
Where: This change applies to Lightning Experience and Salesforce Classic (not available in all orgs) in Enterprise, Unlimited, and Developer editions where Data Mask is installed
