Agreed. The password-reset mechanism and standard 2FA login process should not
both use the same auth path.

I?m not a fan of SMS as a 2FA for all the obvious reasons, but also recognize
that requiring FIDO/TOTP as the *only* supported 2FA is a sure path to tepid
adoption. I believe that we should highly encourage users to prefer those
mechanisms over SMS but not prohibit SMS as an option.

The only reason I can see to limit the number of keys is to discourage the use
of a single account by multiple employees in an organization. I think a good
approach is to have a soft limit (say, 8) that can be increased on request to
help combat this. There should also be a mechanism to delete no-longer-used 2FA
keys instead of simply disabling them (Seems obvious, but I have accounts on
sites that don?t allow this, leading to a ever-growing list of registered auth
apps on various phones shown in my account)
Separate question - is there a workflow for manually resettting/removing user
2FA when users lose their tokens/auth apps/phone numbers/etc? How would ARIN
staff authenticate those requests? Please, please don?t make that process
involve a notary (I?m looking at you, AWS).
Thanks,
-Chris

Thanks for your input Heather.

Approximately 80% appear to have a single human poc

Online
Can we add, authorization should expire in <24hrs? Per markk@ it expires in a
week, which means anyone that gains access to that browser session will be able
to effect changes. Given that we've added more, not less, critical
infrastructure impacting functionality to ARIN online, the security
requirements should be stricter.
Historically, NIST explicitly recommended AGAINST using SMS as 2FA, going all
the way back to 2016.
"Due to the risk that SMS messages or voice calls may be intercepted or
redirected, implementers of new systems SHOULD carefully consider alternative
authenticators. If the out-of-band verification is to be made using the public
switched telephone network (PSTN), the verifier SHALL verify that the
pre-registered telephone number being used is not associated with a VoIP (or
other software-based) service. It then sends the SMS or voice message to the
pre-registered telephone number. Changing the pre-registered telephone number
SHALL NOT be possible without two-factor authentication at the time of the
change."
SMS based 2FA hasn't really gotten any better over the years. I would not be
in support of expanding the functionality of SMS 2FA. Similarly, I would not
support the use of email as 2FA either.

On 1 November 2022, ARIN? announced?that we will require two-factor
authentication (2FA) on all ARIN Online accounts beginning 1 February
2023.?ARIN currently has three options for customers to set up 2FA on their
ARIN Online accounts:
- Time-based One-time Password (TOTP) using an authenticator of your choice
- Short Message Service (SMS) for customers within the ARIN service region
- FIDO2/Passkey-enabled Security Key
Please note: Voice 2FA is not currently available for new 2FA activations; it
is still available to those customers who already have that method set up on
their accounts.
Following the announcement of the planned enforcement date of 1 February 2023,
we received several suggestions for further expansion of our authentication
offerings, including:
- Allowing email as an authentication method
- Enabling SMS support for customers who reside outside of the ARIN service
region
- Allowing registration of multiple hardware security keys.
We are seeking community feedback on these suggestions as well as additional
input on our 2FA options. Specifically:
1. Would you support ARIN offering email as an additional 2FA method?
2. Given that 13% of web user accounts list phone numbers outside the ARIN
service region, should we widen the availability of SMS, or are the other
offered 2FA options sufficient to meet the needs of these users?
3. We agree that users should be allowed to register multiple hardware security
keys. The question is: What is the optimal number of keys that should be
allowed to be registered?
The feedback you provide during this consultation will help us decide the path
forward regarding our 2FA options for ARIN Online. Thank you for your
participation in the ARIN Consultation and Suggestion Process.
