The End User Settings Form is what end users see when they select My Settings from their profile menu (or the My Settings tile on the Service Catalog) in the Self-Service Portal.
It lets them update their own contact details and personal preferences, such as:
Profile photo, first name, last name, and display name
Password
Email and secondary email
Phone number, text message number, and chat nickname
Language, time zone, date format, and first day of the calendar week
Whether to receive automatic SR email notifications
Custom theme
Which of these fields actually appear on the form, and how each one behaves, is controlled by an admin.
