Change Username in ASP.NET

Changing any data such as password or username depends on your business rules. If yu want you can change it but as a general rule, sites do not allow. This change has nothing to do with the platform or technology yuou use to develop this.

So just as you would change a password, you can code to change the username as follows:

1. Make the user login with current username/pwd
2. Authenticate and once valid redirect to the my acccount section.
3. User clicks on Change Username
4. Accept old username/pwd plus new username. Oldusername/pwd will be used to re-authenticate and confirm that the authorised user is making change.
5. Authenticate the user details again and if oldusername and pwd is correct then update the username with the new username.
6. Show confirmation.

I know how the processes works, my question was how to program step 5. I was wondering if the Membership object or any other ASP.NET 2 object handled username changes the same way it handles password changes.

I found a manual way of doing it - change the UserName and LoweredUserName value in aspnet_Users. Since everywhere else the user is referenced by the UserId, changing these two values will change the username. You just have to make sure the username is unique.
