This really irks me to no end with password managers in particular. I like to generate 30 character random passwords and sites that limit input or block paste in the verify field are particularly annoying. Similar for login and 2FA entry fields. There's no good reason for it. I've often gone an extra bit to ensure password managers work well. I wish more sites would do the same.
