Hi there maags1950-gmail-,

QuickBooks Online can be accessed through mobile app and web browsers. There is no additional cost when accessing your QuickBooks Online account via a web browser.

Here's how you can access your account:

1. Log in to QuickBooks Online through https://qbo.intuit.com
2. Enter your User ID and password.
3. Once done, you'll be routed  to your QuickBooks Online account and continue to reconcile your bank account.
4. To reconcile a bank account, click on the Gear Icon, and click Reconcile.
