One of my biggest complaints was that one of the Account Recovery flows was just an emailed 6-digit code. So a 1 in 1 million chance that somebody without access to any of your stuff could hack you by just hitting reset and guessing "123456". It's actually surprising how many other Account Recovery flows across the web I have noticed recently that do the same thing. Not sure if Ory has added the option for more entropy in this code as of today's release though it's been a while since I've used it.
Otherwise it was a great project to work with that has tons of knobs to customize. I commend the authors, aeneasr especially. It must be a ton of work to keep up with all of the auth standards and offer this in an Apache2 licensed package all while building a business around it as well!
They could script this to run over a long period of time targeting 1 account, or they could target many accounts at once, and would probably have success.
