This is pretty incredible. These aren't just good practices, they're the fairly bleeding edge best practices.

1. No more SMS and TOTP. FIDO2 tokens only.

2. No more unencrypted network traffic - including DNS, which is such a recent development and they're mandating it. Incredible.

3. Context aware authorization. So not just "can this user access this?" but attestation about device state! That's extremely cutting edge - almost no one does that today.

My hope is that this makes things more accessible. We do all of this today at my company, except where we can't - for example, a lot of our vendors don't offer FIDO2 2FA or webauthn, so we're stuck with TOTP.

Also, “Password policies must not require use of special characters or regular rotation.”

They even call out the fact that it's a proven bad practice that leads to weaker passwords - and such policies must be gone from government systems in 1 year from publication of the memo. It's delightful.

To be fair, this was part of the NIST guidelines since Mar 2020. A whole appendix was added to justify it: https://pages.nist.gov/800-63-3/sp800-63b.html#appA

Way earlier than that, even.

> Verifiers SHOULD NOT impose other composition rules (mixtures of different character types, for example) on memorized secrets

Earliest draft in Wayback Machine, dated June 2016. Lots of other good stuff from 800-63 dates back this early too.

They accepted edits via pull request when that was in the works! [1] Such a better model of giving feedback or suggesting edits compared to sending in a marked-up PDF.
