Yes, MU support needed, and how to change username at front-end for users?

Hello,

For now, there are manny social login plugin, the usernames are created randomly,and it is convinient for users to login and involve in any activities, but that does not mean the users like the username was created by the social plugins, so it would be much better if any plugin to support for users to change their usernames later at front-end.

is it possible?
