  Efficient identity management system has become one of the fundamental
requirements for ensuring safe, secure, and transparent use of identifiable

information across security domains which increase the portability of their
digital identities. However, it also raises new architectural challenges and
significant security and privacy issues that need to be mitigated. In this
paper, we presented the limitations and risks in Federated Identity Management
system and discuss the results and proposed solutions.
