In some instances you can connect system accounts (i.e. Totara user accounts) to provide advanced functionality for plugins. Connecting accounts isn't required for login functionality, but note that other plugins using the OAuth service may offer a reduced set of features if a system account has not been connected. For example, when using repositories without a connected system account, controlled links for file operations will not be supported.
To connect system accounts, follow these steps:
Go to Quick-access menu > Server > OAuth 2 > OAuth 2 consumer details.
Click the right-arrow icon () in the System account connected column.
Click the Continue button.
Once you have connected an account, the email address associated with that account will display in this column.
