I copied this post from
@homerj650 as I have the exact same problem:
"I had set up everything for syncing my accounts with RBC and it was working fine. Now they have switched to two factor authentication and i am unable to connect. Called them, and they say it's an issue on Quicken's side. Has anyone experienced this with any other bank? When i try to allow the connection i get a "timed out" notification on my phone from the authentication process. Thanks for any help you can give."
Has anyone come up with a solution to this yet?
Cheers,
Randy
