Page Details: User Profile Audit History Tab

The audit history tab in user profiles contains a history of the profile's modifications. It displays information about the creation of the profile and the last modification and contains a table that details the individual fields modified in the profile's history, including the field modified, the old value, the new value, and who made the change and when. Because the audit history table can become so large, the you can use search and filter tools to limit the table's contents based on certain text or based on a specific time period.
