  8. Under the Redirect URI (optional) section, select Web from the drop-down menu and enter the URL https://central.sophos.com. Click Register.



  9. The Azure AD application is now created, and the application's screen will be displayed. Make a note of the Application (client) ID and Directory (tenant) ID as you’ll need this later.
  10. Go to Certificates & secrets. Under the Client secrets section, click New client secret.
  11. Create the client secret by adding a description and selecting the time frame you wish to have the key valid for. Click Add.
