Very interesting news. Improving online security is a win and this sounds 
promising.


Never having used FIDO2 for anything I am left, probably not uniquely, in the 
dark for hardware device support. The only link I found on the ARIN website for 
"hardware keys" was a link to another ARIN page, which as of the time I am 
writing this email, results in a 404.


The page with the link to supported hardware key details near the bottom @ 
https://www.arin.net/reference/materials/security/2fa/2fafaq/

The referenced hardware key details page that is 404 @ 
https://www.arin.net/reference/materials/security/wfa/fido2


I searched generally online for FIDO2 hardware keys and found a lot choices out 
there. Are all hardware keys the same? Will all hardware keys work with ARIN 
Online? I realize this is a brand new offering from ARIN so I am not upset that 
there is little data of the sort I am looking for right now but I would suggest 
ARIN get some better hardware key information on their website for people who 
are curious about but have little or no experience with FIDO2 and hardware 
components. After reading this https://en.wikipedia.org/wiki/FIDO2_Project I am 
wondering, can I simply use a smartphone itself as the hardware token to log 
into ARIN Online? Is there an app needed to do this?

I then discovered this FIDO2 keys page from online searching: 
https://www.yubico.com/store/compare/ which seems like one of many pretty 
popular key makers.
I assume there are possible risks affiliated with buying unknown hardware 
devices and plugging them into our trusted computer systems: key loggers, data 
exfiltration, trojan/malware infections, etc. There are even SFPs with built in 
switches or ones running Linux within the SFP itself able to do packet captures 
and all sorts of fun stuff. All the more reason I would appreciate a 
list/suggestion of well trusted hardware token makers. I did find this on 
Microsoft's website that seems like an easy to digest breakdown of some key 
makers: 
https://learn.microsoft.com/en-us/azure/active-directory/authentication/concept-authentication-passwordless#fido2-security-key-providers

Is FIDO2 just another industry buzzword? Am I the last one on NANOG to get into 
FIDO2 and therefore I am just asking a bunch of moronic questions? I rather 
think not and this time it seems like it may be worth getting buzzword 
compliant.

I realize it is not the job of ARIN to educate its customer base on the ins and 
outs of FIDO2 but I think a little extra working information would be quite 
helpful going forward.

<https://www.yubico.com/store/compare/>Thanks to ARIN for implementing this, 
thanks to those that have pushed for the deployment of this protocol, and 
thanks to those that will respond kindly to me in my ignorance on this topic!!

John - this is a great step forward! Kudos to the tech team who helped make the 
leap - it can be daunting.

Some feedback, take or leave as you see fit, based on my scars:

First, thanks specifically for the support for unique key names (you might be 
surprised at how many services don't!), and for the FIDO2 support of on-key 
PINs.

Second, I'd like to second ;) - but go beyond - Job's feature request for 
multiple-key support, both in count and additional UX. Support for *more* than 
two keys is recommended, to fit a wider variety of use cases and threat/risk 
models (connector availability, shared/role accounts, offsite key backup, etc 
etc). From my survey of 50 providers of U2F / FIDO / FIDO2, key-count support 
ramps up quickly from one (PayPal - come on, y'all!), two (Bank of America), 
and five (AOL/Yahoo and Coinbase), with the rest supporting *ten or more keys* 
(and yes, higher key counts have use cases, though user experience degrades 
above ten keys). And when multiple key support is added, please consider some 
UX around managing the list of keys (like allowing the user to *modify* key 
names without having to delete and re-add them, showing the timestamp, IP, OS 
family / platform, etc. from where the key was last used). Great key UX 
examples to emulate in this space include Dropbox and Google. (And showing the 
IP's ASN would be a uniquely ARIN twist. :D )

Third, please consider allowing a mix of authenticators (instead of the current 
exclusive choice among TOTP, FIDO2, and SMS). While it will be excellent to 
allow users to *eventually* opt into exclusive use of security keys (as with 
Google's Advanced Protection Program) ... doing so with a *single* key 
unacceptably shifts the risk model for some users. A mix allows users to manage 
their risk model directly, often by voluntarily using FIDO2 first to get the 
phishing resistance / origin verification of FIDO2, but mitigating single-key 
risk with fallback to TOTP (which may be more fluidly available than the 2FA 
recovery codes, etc.).

But the hardest part - going from zero keys to any - is already done. Really 
appreciate it!

Royce
