To reset the admin password, you can run the following SQL command against the CxDB database.
This will reset the password to "admin":
[Password] = 'hlTgLz69abv2jGHWAyj57N8MO3K4L8uBY93mEe0K3JE='
,[SaltForPassword] = 'nTwTPeNHlHdhcxk0IXapiQ=='
,[IsAdviseChangePassword] = 0
WHERE [UserName] = 'admin@cx'
ATTENTION: the name "admin@cx" is not mandatory. If you admin's username is different, replace this with the correct username.
