Hello @qbelfor
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. There's no way to currently default to an option with 2FA even with only one available. If you'd like you're available to make this into an idea to see if this could be added to quicken. I'll leave a link below on how to do so. I do apologize for any inconvenience this has caused.
