Changing the Super Administrator Username and Password

WSO2 IoT Server has the admin user created by default. This user is also known as the super administrator as it has all the permissions assigned to it. The default username and password of this user is admin . In a production environment, if you are using the admin user for administration purposes, it is recommended to change the username and password.

Changing the username and password using the script

This script automatically changes the username and password of the super administrator users. This method is recommended because manually changing the username and password includes many steps and if you miss out on a step you will run into errors.

If you are running the script, you need to have started WSO2 IoT Server atleast once. Therefore, if you are running WSO2 IoT Server for the first time, follow the steps given below:

3. Restart the analytics profile:
```
