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 Basic Auth Prompts | Bitwarden Help & Support 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?
