How to use Basic authentication


I’m trying to save a basic auth prompt but after I’ve logged into the device, BW never pops up to save the login. I’ve seen but it refers to working “if there is only one login item with a matching URI.”. I’m not sure what a ‘login item’ is.

Also the animation on that page doesn’t, well, animate. Tried two different browsers.
Can anyone explain how it is meant to work?
