Robinhood and Webull both support 2FA for login. This can help protect you from an attacker making unauthorized trades in your account.

    According to this article:

    https://support.tastytrade.com/support/s/solutions/articles/43000578659

    tastytrade supports 2FA for certain activities:

    • Changing your email address
    • Changing or resetting your password
    • Linking your bank account
    • Initiating a withdrawal

    Interestingly however, they don't support 2FA for client login.

    So, if an attacker gets a hold of a victim's password, they could do the following:

    • They go in and purchase far OTM 0DTE SPX options.
    • The attacker is on the other side of the trade in their own account (selling those at a price lower than the default ask).
    • The attacker collects the premium.
    • The victim is out that money.
    • Let's suppose the victim was away from the markets that day so the transaction completes.

    As far as I can tell, the victim would be out that money.

    What do y'all think? For those who use tastytrade, does this scenario concern you?

      I have a highly complex and long random password, so I’m not worried about it being compromised. I have TOTP set up, but I don’t feel that it’s necesary for more than what they use it for. I need to give them TOTP for any money movements into/from the account, anything involving my credentials, or changing banks.

      I would prefer they supported my Yubikey for that, but I feel that they’re applying it in the places it’s needed most.
