Authentication error basically means “wrong login details.” Most of the time, it’s caused by incorrect Company File login. MYOB account login is normally your email address, and company file login is by default just “Administrator” with no password.

If your Company File login/password combination is incorrect, you will always see “Authentication Error” when invoicing or importing data from MYOB.
