login (AKA sign-in) is a feature of many websites where a user is asked to provide a username (often an email address) and password in order to gain (more) access to the site; the IndieWebCamp wiki uses IndieLogin for delegated sign-in; other sites or services directly use IndieAuth for delegated sign-in.
