The Social Connect service allows users to log in to 123 Flash Chat using their Facebook, Twitter, MSN, Yahoo, and other social network accounts.

Icon indication: A small social icon will be displayed on the gender avatar of a user in the user list.

Furthermore, users can create linking to their social network accounts, to automatically update the status or invite their friends to join the chat room more easily. Last but not least, users can automatically log into the chat room for the next time they link, because it is remembered.
