What are SSH Certificate Authority solutions?
In the quick search I learned about ssh cert authority which looks very manual and also like a dead project smallstep's step-ca who put together very nice article about how to begin certificate authority process Netflix' BLESS is AWS only Cashier which also looks quite ok

Use TouchID to Authenticate Sudo on macOS
For Windows, it seems it's possible[0, see footnote], however there are problems like general incompatibilities [1], and official support status is " We have this in our backlog. At this point it's not prioritized.".

0.footnote: "Windows Hello also supports other types of authenticators like internal TPM device(if they support generating ECDSA or Ed25519 keys, they can be used instead of FIDO/U2F security keys)."

Hardening SSH
Awesome article! Also found this tool (tavrez/OpenSsh-sk-winhello) for windows that lets you do this without admin access

[QUESTION] Is there a best way to manage multiple SSH on multiple Yubikeys?
Which is also how they are generated when retrieving them on a new computer via ssh-keygen -K since I used the application=ssh:yubikey_5 flag when first generating them. So something like ssh-keygen -t ed25519-sk -O resident -O application=ssh:yubikey_5c, but because I am on Windows I also had the -w winhello.dll flag (In case anyone stumbles on this question)

Using Yubikey FIDO with ssh-agent on macOS?
This is what i used but YMMV https://github.com/tavrez/openssh-sk-winhello/releases/tag/v2.0.0

Tell HN: GitHub no longer supporting unauthenticated `git://`
> Because AFAIK, (Fido) yubikey support is still missing.
Correct, hopefully Microsoft will provide an updated SSH client soon. It only requires recompiling OpenSSH with the correct flags.
Alternatively, use these build instruction for openssh with FIDO for windows:

> Using either the PKCS#11 support or the gpg applet requires some extra piece of software
For those wanting to do that, here are some ways:
Using a premade dll:
https://github-wiki-see.page/m/mooltipass/minible/wiki/Setti...
Or with a middleware:
https://github.com/mgbowen/windows-fido-bridge
Using the Hello API:
https://github.com/tavrez/openssh-sk-winhello
Given how many people came with their own ways, I believe there's enough demand for Microsoft to fix that.

How often should I rotate my SSH keys?
My knowledge of WebAuthn is limited but their invocation of the relevant API seems like it should work for fingerprints also.

certificates - 🛡️ A private certificate authority (X.509 & SSH) & ACME server for secure automated certificate management, so you can use TLS everywhere & SSO for SSH.
libfido2 - Provides library functionality for FIDO2, including communication with a device over USB or NFC.
the-bastion - Authentication, authorization, traceability and auditability for SSH accesses.
windows-fido-bridge - An OpenSSH SK middleware that allows you to use a FIDO/U2F security key (e.g. a YubiKey) to SSH into a remote server from WSL or Cygwin.
cashier - A self-service CA for OpenSSH
