If the connection with MYOB Payroll is needed to be disconnected either permanently or temporarily, following screenshots are needed to be followed:

Click on the MYOB Settings tab in order to view the MYOB Settings.

If you wish to only end the current MYOB session, simply click on Unauthenticate Payroll button without selecting the checkbox.

And if you wish to delete all the MYOB Payroll related data (employee assocaitions, etc) stored in the SINC. Click on the checkbox for Delete MYOB Payroll related data and then click on Unauthenticate Payroll button as shown below.

Once the unauthentication (with delete MYOB-related data as checked) is successful, you will be shown that your current session has been terminated and the next time you wish to authenticate, you will have to go through the MYOB authorization process again.

​Keep in mind: You have to be careful when un-authentication process is underway because if the checkbox Delete MYOB-related Payroll Data is selected, it would delete all the data that is stored in SINC permanently. Hence, there will be no alternative way to restore the deleted information.
