Hi I had the same problem (I forgot my password). To reset the password stop and exit the codesys control win systray application. Go to folder c:\Users\All Users\CODESYS\CODESYSControlWinV3x64\ and select the folder displayed.
Inside remove these files:
.GroupDatabase.csv
.GroupDatabase.csv_
.UserDatabase.csv
.UserDatabase.csv_
.UserMgmtRightsDB.csv

Open and start the codesys control win systray application. When you try to connect again via codesys you are able to give a new username and password.

Hope this helps
