Air Canada’s online account system required a 6 character password, which was secretly converted via T9 to 6 numbers on the back end, meaning “aaaaaa” and “bbbbbb” were effectively the same password, and this was only fixed in 2018
My personal theory is that it’s a remnant of an old system that was only accessible by phone (hence the 6 digit pin), and they simply grafted an online component on top of it
Unless they’ve changed it very recently, Wells Fargo’s passwords are case insensitive

That sounds like someone who topped out with highschool level programming tried to implement a hash algorithm.
