Wish you’d work on this, please, or let us know why you don’t think it’s a good idea.
I particularly hate not having this for sites/apps that don’t show the username and password in the same screen. That means I have to type my password twice. It’s a real pain on Android, with a complex password and a thumb-keyboard.
It’s the same for copying a username and then a password.
Not having it makes bitwarden less secure because most people will just turn off password re-prompt for the annoying site. There is one that I use every day.
