Hi there, the authentication is based on using your software.
If you are not using MYOB on the weekend, you will not need to take any actions and you wont be prompted to authenticate (as you arent trying to access the software)
If you were using the software every day, then you would be prompted to complete 2FA at least once per day (every 24 hours)
If I can please ask that you update your username as well to ensure it is respectful of MYOB and the community that would be great. You can do this by clicking on your profile on the top right > my settings > edit username
