You can make a fake password input with type text using a custom font:
@font-face {
font-family: 'password';
font-style: normal;
font-weight: 400;
src: url(https://jsbin-user-assets.s3.amazonaws.com/rafaelcastrocouto/password.ttf);
}
input.key {
font-family: 'password';
width: 100px; height: 16px;
}<p>Password: <input class="key" type="text" autocomplete="off" /></p>JSBin Demo
Notice that this only raises more security concerns.
