Just installed Monterey on my MBP and am giving the new Safari two-factor authentication magic a whirl. So far, mixed results for autofill from websites, but it’s early. Where it does work, it’s phenomenal.

This post by Dan Moren from Six Colors helps you migrate Authy two-factor codes to Safari. it is a little tedious, and depending on how your Authy is set up, it may require a little trial and error, but it works – a massive timesaver especially since I don’t plan on additional migrations to Monterey or iOS 15 for a while yet.
