Once logged in, click on your name in the top-right corner of the page, and click on My Account.
On the Profile page, you can update your Name, add Initials, add Title, and add your Mobile Number. You can change the Language in which you want to receive email notifications and the Time Zone you are in.
You can also add an Email Alias, which would appear, instead of your first and last name, in the Email notifications sent.
Once done, click on the Save button to keep the changes or the Cancel button to revert the changes made.
