Basic Auth Prompts
Login prompts like the one pictured below, called "basic" or "native" authentication prompts, will be automatically auto-filled by Bitwarden browser extensions if there is only one login item with a matching URI. You can also use the browser extension's Launch button to automatically open and log in to a basic auth-protected resource.
Auto-filling on basic auth prompts will, by default, use the Host URI match detection option so that auto-filling is more restrictive. This can be changed by setting the match detection option for the relevant login.
If more than one login with a matching URI is found, the browser extension will not be able to auto-fill your credentials and you will need to manually copy/paste your username and password to log in.
If a single login item is present for a matching URI, the credentials will be autofilled in the background and no authentication prompt will be shown.

note
Due to the way basic auth prompts are designed, auto-filling must be non-interactive. This means you cannot auto-fill on a basic auth prompt using the
Tab view, context-menu, or keyboard shortcuts.
