In the "Security" tab on the Account Settings page, you can turn on two-step authentication for an extra layer of protection in your account.
You’re prompted to enter your phone number, and a 6-digit security code will be sent to you to verify your account.
When you sign in to your Option Alpha account, you’ll enter your password and receive a prompt to enter the security code.
Two-step authentication is only available for live trading accounts. You can turn off two-step authentication at any time.
