User credentials are data elements that identify a user to your application. The user identifies themselves by asserting their user credentials for authentication against a valid user account.

The data elements required for user credentials depend on the authentication system and the features you enable in an OpenEdge database. At a minimum, these are the data elements required to initialize a security token that represents the user's identity. For more information on working with user credentials, see Specifying user IDs and passwords in ABL.
