Abstract
Aspects of the present invention provide an approach for user authentication during a user session which potentially requires multiple user authentications. A library of authentication methods is provided for preforming the user authentications. For authentication, a threshold contribution value is set which needs to be exceeded for authentication to occur. To carry out the authentication, a chain of authentication methods is constructed at run time, selected from the library in order to provide an aggregate contribution value which exceeds the threshold. During run time, the contribution value of each authentication method is dynamically adjusted, so that construction of the chain uses current amounts for the contribution values of each authentication method. This allows the chain to be reconstructed at run time taking into account changing circumstances. Specifically, not yet executed authentication methods may be unlinked from the chain and replaced with one or more new ones.
