@wlhunt Is anyone still using Parameter Image Plus model? Should we keep maintaining it? It has auth language in it here:

slycat/web-server/plugins/slycat-parameter-image-plus-model/ui.html

Lines 61 to 64 in 48ab559

	<label for='remote-username'>Username</label>
	<input id='remote-username' type='text'/>
	<label for='remote-password'>Password</label>
	<input id='remote-password' type='password'/>
