Every additional "line of information" in a pop-up notice reduces the probability that any of it will be read.

Right. So the better option is to secure passwords slightly by default. I suggested the additional information for those that feel that securing passwords is "lulling users into a false sense of security".

Either you make some attempt to secure the passwords, or you let your users know that they are readable in plaintext. Don't do neither, like Chrome is doing.
