Security Key Two-Factor Authentication

FIDO2/Passkey-enabled security keys provide two-factor authorization through the use of a physical hardware device to verify identity in addition to the conventional login and password combination.

Any FIDO2/Passkey-enabled hardware is compatible with ARIN’s two-factor authentication, though only one key can be registered to an individual ARIN Online account.

Supported Hardware Devices

In our development of Security Key 2FA, we tested our systems with these security keys:

  • YubiKey 5C
  • SoloKeys Solo USB-A
  • AuthenTrend ATKey.Pro Type C
  • Google Titan Security Key

We tested each device on Mac OS with Safari, Chrome, and Firefox and tested each device on Windows with Chrome, Firefox, and Microsoft Edge.

Enabling Two-Factor Authentication Through FIDO2/Passkey

  1. Log in to your ARIN Online account. If you have yet to set up two-factor authentication, an alert will appear on the Dashboard which reads ‘Two-Factor Authentication is not set. Configure it now.’ Select Configure it Now. (Two-factor authentication settings can also be accessed by selecting Settings from the menu under your name.)

Recovery Codes

Important: Save your 2FA Recovery Codes in a password management tool, print it out, or write it down and store it in a safe place. These codes will only be displayed once.

Each 2FA Recovery Code can only be used once, though they can be used in any order.

Select Activate 2FA to complete the setup process.

What happens if I want to update to a new security key?

Your ARIN Online account will be associated with only the most recent registered security key. If you wish to replace your current key with a new one, simply register the new key and it will disable the previous one.
