      Sign-in error: "The email address and/or password used for authentication are invalid"

      There are two reasons you might get this error.

      • You have an MYOB two-factor authentication (2FA) account, but you forgot your password or used the wrong on – for example, your 2FA password might be different from your MYOB Acumatica user profile password.
      • You normally use the green Sign in button, but you tried the purple Secure Authentication button. This means you probably don't have a 2FA account.Sign in using the green button
