After you sign in to your Oracle Cloud Account, one of your first tasks is to create additional account users. For example, you can create a user for each member of your team. Each team member can then sign in to the account with their own credentials. You can also assign each user to specific user groups, and apply specific security policies or roles to each group.
If the users you create will be using the services available from the Infrastructure Console, then you can use the Infrastructure Console to create your additional users.
However, if the new users will be managing Platform Cloud Services available from the Infrastructure Classic Console, then you'll use the Users page in Infrastructure Classic Console to create and manage those users.
If the new users will be managing Oracle Cloud Applications available from the Applications Console, then you'll use the Users page in Applications Console to create and manage those users.
