Was there ANYONE
Who believed that voice authentication over the phone was secure even on the day it was introduced? I'm sure it is and always has been less secure than either fingerprint or facial identification on smartphones, and the potential weaknesses there have been discussed at length in these forums over the years.
Banks using voiceprint auth will be forced to give it up for something more secure, just like they will (eventually, someday...right??) be forced to give up SMS 2FA which unfortunately my two main banks still use - I get hit with it every time I login after I've restarted my browser (every few weeks) since I have it set to forget all its cookies. At least my brokerage skipped SMS 2FA and went directly to app/hardware key based 2FA and as that's where I have most of my money that's what I need to be the most secure!
