We don’t need this much security. Require a thumbprint or password at initial login on the iOS app but don’t require every time I switch to that app. I switch back-and-forth from email and other trading apps and it is extremely annoying that I have to authenticate every time I switch back to the app. Give the option for a security timer to not prompt for authentication for 8 hours or 1 day so we don’t have to continually re-authenticate when going back to the app.
