What is an E-Authentication Credential?
An E-Authentication credential is a standard form of user identification that is issued by a Credential Service Provider. There are different levels of credentials that are issued based on the security requirements of the application you are accessing. The National Institute of Standards and Technology (NIST) has defined four assurance levels. Levels 1 and 2 are user IDs and passwords, while levels 3 and 4 require additional security measures.
