When a user logs into a Web site or into an ATG product, a UserAuthority object authenticates the user’s login name and password. A user authority determines identities throughout the ATG security system. The Personalization module provides several user authorities that are configured out-of-the-box. The /atg/userprofiling/ProfileUserAuthority component controls security for the profile repository user directory.

For more information about the UserAuthority object, see Security Services Classes and Interfaces in the Managing Access Control chapter of the ATG Platform Programming Guide.
