Thanks for posting here in the Community. Allow me to step in for a moment and share some additional information about logging into your Intuit Account.
Yes! @Anonymous is right. The User ID and Password that you use to access your company file is not the same as your Intuit Account unless you set it up that way on purpose. If you already have an Intuit Account and don't remember your User ID or Password, you can recover it by following the steps below:
1. Visit this link: www.quickbooks.com/account.
2. Choose Forgot your Password? or Forgot your User ID? Then, follow the steps to retrieve your Password or User ID.
That's it! Please let me know how it goes or if you're referring to something else by leaving a comment below. I'm only a post away should you have any follow-up concerns. Have a great rest of the day.
