Subject: [ARIN-consult] Consultation on Expanding 2FA Options for ARIN
Online
Message-ID: <348341ba-2812-466e-ab94-b59fb9d04...@arin.net>
Content-Type: text/plain; charset="UTF-8"
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.
Please provide comments to arin-consult@arin.net. You can subscribe to this

This consultation will remain open through 5:00 PM ET on 7 February 2023.

You should not limit SMS to the "ARIN Service Region" since by ARIN's own
bylaws, people outside that geographic region can be ARIN customers.

Functionally infinite. Why on earth would you set a hard-coded limit? It's
not like an additional database table is expensive. If you have to set a
limit, it should be something large like 2^32.

*No.* Email can be used to reset one's password. If it's used for one-time
login codes as well, that's only one authentication factor. An email
compromise could therefore easily result in account takeover, which defeats
the purpose of 2FA.

I am against SMS 2FA being offered as an option at all, so I'm ambivalent
about this.
> 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?
I can't see someone reasonably needing to register more than a handful, but
I also don't think there's a good reason to set a low limit. I think 10 is
a reasonable upper bound.

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.
Tangentially related, what percentage of accounts do you think have a
single human poc?
