Robinhood Accounts Looted, No Customer Support

A lot of the alternatives aren't much better. Fidelity for example would allow you to input your password as the numerical equivalent (think phone keypad - A, B or C map to "1" and so on). Which basically requires modifying your password before hashing it (and dramatically reducing entropy in the process).

I'm not sure if they still do this.

I think I recall Vanguard having had something similar but I can't find it in searching, so perhaps not.

According to Fidelity's website [0] they still do so ("You'll be asked to enter your username and password using the keypad on your phone.").

I basically assume any financial institution that provides support for the old "telephone banking" methods via DTMF tones either stores your password in plaintext or a hashed version that reduces entropy. I'm honestly surprised hackers haven't gotten sophisticated enough to bruteforce these reduced entropy login passwords using a Twilio account.
