You can generate Client ID and Client Secret API credentials for MSP App accounts for use with other applications (Managed Workplace, Automate, Continuum, etc.).
These credentials are valid until you delete them.
The Copy feature also allows you paste the credentials to your clipboard to make it easier to enter into another application. The copy icon is shown below.
Note that you must copy and save the Client Secret elsewhere immediately because it only displays until the page is refreshed.
