When you use any Intuit product, you’ll need to create an Intuit account that has, among other things, a user ID and password. You can use this Intuit account information to access all of Intuit’s powerful products.
If you update your Intuit account user ID and password in one Intuit product, they are automatically updated across all Intuit products you use.
