Have you considered using MFA

With the addition of MFA it made it hard to automate trading, but this is still possible with a Python package:

library(RobinHood)
library(reticulate)
pyotp = import('pyotp')
mfa_code = pyotp$TOTP("AUTHENTICATOR_CODE")$now()

RH = RobinHood(username, password,mfa_code)

You could change the mfa_code entry to AUTHENTICATOR_CODE

I have made a series of comments on my own package but could not push a branch back to you: https://github.com/exploringfinance/RobinHood
