Multi-factor Authentication (MFA) is a secondary security measure implemented by Tradier Brokerage to keep your account secure. It requires you to receive a 6 digit code (not your password) via email or text message and enter the code on our website. It is a required step to access your account and cannot be removed. If you log into your account from the same device on the same IP address, MFA will be bypassed after successful completion of the process the first time.
