Abstract

Method and systems for single sign on with dynamic authentication levels is described. The method include receiving a data request for access to a second application, where the user is already authenticated to the first application at a first authentication level. Application information about the authentication level necessary to access the second application is retrieved. In response to a request, the user provides the further authentication data for accessing the second application. The type of the further authentication data required is based on the first authentication level and the minimum authentication level necessary to access the second application. The user is then authenticated to the second application at the minimum authentication level necessary to access the second application.
