Got a true recent funny story (true) for you while we waitJust before covid started I was just starting work and opened one of my trading accounts. I used my userid, password. And even answered my security question. Closed and opened my account several times.
I was surprised to find my account had $8 million in cash and about $11 million in securities ~. Now the name on my account in the header was different. I think a clerk had an oh p##p moment. It corrected the next day. Computers huh?
