+[[!tag type/auth]]
+
+This plugin lets users log into ikiwiki using any email address. To complete
+the login, a one-time-use link is emailed to the user, and they can simply
+open that link in their browser.
+
+It is enabled by default, but can be turned off if you want to only use
+some other form of authentication, such as [[passwordauth]] or [[openid]].
+
+Users who have logged in using emailauth will have their email address used as
+their username. In places where the username is displayed, like the
+RecentChanges page, the domain will be omitted, to avoid exposing the
+user's email address.
+
+This plugin needs the [[!cpan Mail::SendMail]] perl module installed,
+and able to send outgoing email.
