How do I make them both the same????

The situation is this, a user desires to change his USERID at login to match a desired display name. Seems a fat-finger entry messed his login USERID

There is a method to change the display name. That is not a problem. The issue comes with changing the USERID needed to login.

As I see it, I can either delete the account and re-enter with the correct USERID or, I can edit the MySQL table to make the correction there.

Any other method that I am overlooking????
