We are aware of an issue with updating E*Trade accounts after enabling the mobile Two-Factor Authentication option. The expected process is that the account would prompt users to re-enter their credentials including the token provided by the app, however reports are indicating that there is no prompt for the token.
While we work on this issue with our aggregation team, we recommend disabling this option temporarily. Once we have a resolution in place we will update this space with additional information.
We apologize for the inconvenience and we appreciate your patience and understanding!
