Why Do I Receive Two Verification Codes to Register for MyIR?

In order to successfully register for MyIR Mobile and utilize its features we want to first verify that the phone number is a valid number, the second one is the MFA code to successfully complete your registration and use MFA to sign in on all subsequent logins after.

Can I use my email or landline phone instead to access my MFA codes?

Currently, our MFA (Multi-Factor Authentication) access provider only allows access through the SMS service on cellular devices.
