Why can't I copy/paste passwords into the import brokerage logon screen?

It seems ridiculous to me that this problem has now persisted for at least 3 years.  In addition to not being able to copy and paste strong passwords from a password manager, you can't see what is being typed into the password field as you type, making errors highly likely. I've been a TurboTax customer since the 90's, and if there is no satisfactory response from Intuit, this problem is so frustrating that I think that the only solution is to go with a competitor's product. I don't want to have to install another program, such as Auto Hot Key, just to be able to copy and paste the password.
