I am developing a web application which contains a user login. In the web I have seen that many web applications do not allow users to change the username once the account is registered. Is there any reason for that?

  • I have recently came across this dilemma whether to allow user to change username. I have entered it on my blog: http://www.dizkover.com/post/423/programming-why-not-to-allow-users-to-change-username-in-social-web-application-design – Ross Jul 08 '13 at 05:45

I think it's more personal preference to be able to keep track of who posts what rather than any real security concern. I see no security issue in allowing a user to change their username, but you will have users that try to imitate other usernames and admin usernames to confuse and possibly socially engineer information.
