The Java Authentication Service Provider Interface for Containers (JASPIC) is a standard that defines authentication service providers' interfaces. It comprises so-called Server Authentication Modules (SAM), pluggable authentication components, which are added to the application server.

This standard offers powerful and flexible ways how to implement authentication. Server vendors can ship their own implementation of SAMs. However, implementing authentication modules using the JASPIC standard is seen as quite cumbersome by a lot of developers. This is why the JASPIC standard is not widely used in enterprise projects.
