And specially, not to forget, the immense number of social sites like Facebook, Orkut, Bebo, Twitter etc,. And because these passwords are for the purpose of more compellingly authenticating the identity of one’s computing device to another, passwords have significant disadvantages (they may be stolen, spoofed, forgotten, etc.) So, with all these disadvantages managing different passwords may be a cumbersome task.

All these behaviors can compromise network security.
