QuickBooks® allows you to setup Users & Passwords. This allows you to secure your data. In setting up users you can also assign rights to the user. For example, you may have someone who helps you with your billing and receiving payments. You would set them up to only be able to see the accounts receivable information.
To setup users and passwords:
1. Click on Company from the Main Menu.
2. Click on Setup Users and Passwords.
3. Click on Set up Users.
The User List box will appear. This lists all of the users that are currently set up. The Admin account is set up by default. You may want to set a password for the Admin account, click on Edit User. Enter the new password and enter it again in the confirm password box. Select a challenge questions, and input the answer. When you are finished, click on Next. Click on Finish to complete the process. 
Now we can add Users to your QuickBooks® file.
1. Click on Add User. Type in the name they will use to log in with and a password. Click Next.
2. Choose Selected Areas of QuickBooks®. 
3. Since Julie is going to be helping with billing and receiving payments we will want to give her full access on the Sales and Accounts Receivable window, choose Full Access and click Next.
4. Go through the additional windows and choose the options that fit your user.
5. Once you are done you will see a summary of the choices you picked. You can now review them and then click Finish. It is a good idea to log off and then log back on as them so you can test it out and make sure you have selected the right choices.
