Looking forward to 2FA/U2F in WordPress

Very happy to see folks working on getting 2FA and U2F worked into the WordPress core! I finally got SSL set up on my multi-site install this year, and have been wanting to get this additional layer of security integrated. I ran into a couple of minor issues, which are already listed at GitHub (UX of enabling Google Authenticator/TOTP was a bit confusing, and the fact that a FIDO U2F key has to be associated with *every* site of a multi-site install independently to work on all of them), but I’m sure these issues will be worked out in time. Keep up the good work!
