What shocks (and irritates!) me is that Charles Schwab keeps wanting me to set up voice ID. Why would I want to set up a voice ID for something that is now trivially spoofed?
When was the last time you encountered this? I remember getting nags up until around the end of last year, but not lately. I like to think they dropped the program because I expressed concerns about it to so many reps, but more likely I've just been dialing in on a different number.
Schwab used to have an 8 character maximum on passwords (although at least they changed that). They have never been a paragon of good security practices.
