A lot of websites allow to use either social login (google/microsoft etc) or custom SSO (azure active directory/okta etc). For those, we normally don’t require password but a user can have multiple accounts for those.
I can currently create bitwarden item with username and without password for these. I suffix item name for these with (google auth/microsoft auth etc) but it would be helpful to specifly some sort of color/visual indicator to classify password items to at a glance identify one type of item from another e.g. I can have Microsoft items in color blue, google in color yellow. Normal items in color white etc
