Hello @KyleB
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. In this case it would be up to PayPal to have a way for us to be authorized without having to put in the code every time. From personal experience it was having to type in the code each time for PayPal or have 2FA off as well. I would recommend trying to contact PayPal to see if there's a way to authorize Quicken. I do apologize for not having better news.
Thanks,
Quicken Francisco
