In general, use UnsecuredLayoutsPageBase as a base class for pages to which even unauthenticated users must have access, such as a login page.
For a page base control to which access can be limited to users who possess certain rights, use LayoutsPageBase.
Typically, a class is created in a code behind the file (.aspx.cs) that derives from UnsecuredLayoutsPageBase. The .aspx file, in turn, inherits from the custom page class. For example, the %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\LAYOUTS\login.aspx page that ships with Microsoft SharePoint Foundation 2010 inherits from an internal class named LoginPage, which itself inherits from UnsecuredLayoutsPageBase.
