Configuring Sign-In
By default, Liferay DXP uses the Sign In widget to authenticate users.
The Sign In widget appears on the default home page at http[s]://[server-name:port]/web/guest/home. If the Sign In widget is unavailable on any page, it can be accessed directly via its URL: http[s]://[server-name:port]/c/portal/login.

You can configure other methods of authenticating users and/or applications:
Authentication Verifiers can manage authentication for remote applications, and Authentication Pipelines define the ways users are validated by one or several systems.
