The My Profile section, found in the expanded Home menu, displays your record from the Employee table. On the Contact Information tab you can see all your personal details. The email address specified here is used by the system to send and receive notifications, reminders, reports and so on. The cell phone number is hard-coded and used when two-factor authentication is enabled. You can also view and change your user login details in this section. 

The Job tab displays employment specific information, as well as your work and home addresses.
