Trying to make a send from a test account (which I have used before to make sends) results in two messages of "wrong password" (hihgly unlikely, please allow for a visible password input!) and the third try results in a short "could not unlock signer account" message. A 4th try finally brings the send on its way.

For this test account the passwort is extremly simple. I can not really imagine to have it mistyped. But I would clearly prefer to have an option to see what I type!
