Hi nicofars,

Thank you for taking the time to join in on the thread. I've got some information about your concern.

I see the convenience of not having to authenticate every time you sign in to QBO. This is already a feature in your browsers. You'll want to be sure that their password-saving features are enabled and cookies are not autodeleted when you exit from a page. Please refer to your browser's manual or reach out to their support team about this.

My colleagues have shared good references for MFA, You can check them out when you need references for the said feature.

I'm just a comment away if you have other questions in mind. Have a good one!
