When you first access the Composable Architecture Platform console you are presented with a login screen as shown:
You can select the preferred language to use for accessing the system. If you change the language, the login page will change accordingly. The language you select will be stored as a cookie within your browser, so you only have to select it once.
You can now sign in using the user ID and password provided by the system administrator. If you are the system administrator and this is the first time that you are signing into the system, you can use the word admin for both the user ID and password.
Note that both user IDs and passwords are case sensitive.
