Abstract: We considered that  each vertex of ring Cn of a   super sungraph Gs(Cn,ai) was added with a path of length two, and the super sun-graph obtained was the characteristic of  module p edge magic graceful graph. The results show that the super sungraph that constructed with n trees and joint Ti(i∈［1,n］) with n-1 edges are module p edge magic graceful graph.

Key words: graphical password, super sungraph, module p edge magic graceful labelling
