We have two computers on line. All of a sudden one has to call in to get code to log in, the other doesn't. ????

I’m glad to share some information with you when logging in to QuickBooks Online, @imfrust8ted.

QBO is a web-based program that allows you to access your account through any browser as long as you’re connected to the internet.

Usually, the automation of credentials is in the browser settings or the device itself. You can check their setup or reach out to an IT expert with this matter. That way, the other computer will no longer ask for a code every time you log in.

For the best experience, check out this article about system requirements for QuickBooks. This helps ensure it is compatible with your system.

Don't hesitate to drop a comment below if you have any other QuickBooks concerns. Wishing you continued success!
