Your administrator will have created a username for you when your account was created, but you are able to change it to something more memorable if required. To do this, log into SMB and open the settings menu by clicking on your name in the top-right corner of the screen. From the menu, select “My Settings” to access your settings page.
On the page shown, update your username as required in the “Username” textbox and click “Update Username” to apply the change. If the username has already been used by another employee within your organization, an alert will show and the change will not be made. Otherwise, the username will be applied and you will be able to use this new username the next time you log in.
