If you’re trying to log in to MYOB Essentials and receive a message that says you’ve entered an invalid user name or password, you may have entered either your user name or password incorrectly.
First, make sure that the user name you're entering is the same as the one you received in the activation email when you registered your MYOB Essentials business. Then, make sure you’ve entered your password correctly. Remember that passwords are case sensitive.
If you’re sure that your user name is correct, it may be that the password you’re using is incorrect. In this situation, you can reset your password.
