When you log in to Merchant Portal for the first time after we’ve enabled MFA, you’ll get a prompt to secure your account. Then, you need to designate your “primary” authentication method by selecting one of the following options:
Your verified email, which was used during the Merchant Portal registration process
A text message (SMS) to your mobile phone
An authenticator app installed on your device (such as Google Authenticator, Authy, Duo Mobile, or Microsoft Authenticator)
Once you select your primary method, you’ll receive a verification code. Just enter that code when you log in—and you’re done!
