When you start using QuickBooks, you are required to create an account. Then QuickBooks will automatically generate an admin Id. Now QuickBooks allows only the administrator to make changes in QuickBooks and access all the features of QuickBooks. Unfortunately, you may get a critical situation when you forget your administrator password. But don't worry; you can easily reset your password by going to the 'I forgot my password' page. There you will be required to enter some information and easily can change your password. You can also contact at QuickBooks customer support phone number for further support.
