SMS Multifactor Authentication
SMS multifactor authorization (MFA) relies on the delivery of a one-time passcode through text message to be input in addition to the conventional login and password combination.
ARIN provides support for SMS MFA for some countries in our region, detailed below. If SMS MFA is unavailable, you will need to utilize an authenticator app or a hardware key in order to enable multifactor authentication on your ARIN Online Account.
Enabling Multifactor Authentication Through SMS
- Log in to your ARIN Online account. If you do not have multifactor authentication enabled on your account, you will be taken directly to the setup process.
- Under the first step of ‘Select Method,’ confirm your choice of ‘Text Message,’ and select Continue.
- Under the second step of ‘Verify Method,’ Enter your mobile phone number in the field and select Send Code.
- You will be prompted to enter the code delivered by SMS, and then select Continue.
- You will be provided a set of 16 Recovery Codes that can be used if you lose access to your authenticator or phone number. You can enter any of these codes once each to log in to ARIN Online.
Important: Save the 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 MFA Recovery Code can only be used once, though they can be used in any order.
Select Activate MFA to complete the setup process.
