 ## Get Credentials
 
-Prior to any catalog or service request to the [HERE Open Location Platform](https://platform.here.com) (OLP), you must obtain authentication and authorization credentials.
+To create catalog or service requests to the [HERE Open Location Platform](https://platform.here.com), you need to have the OLP authentication and authorization credentials.
 
-The following approaches are available for authenticating to the OLP within your application:
+The following two authentication approaches are available within your application:
 
-1. Using the _platform credentials_ available from the OLP portal in combination with the HERE OLP SDK for C++ authentication library.
-2. Using the access key ID and access key secret in the platform credentials as described in the [Authentication and Authorization Developer's Guide](https://developer.here.com/olp/documentation/access_control/topics/introduction.html) to create your own authentication and authorization client for retrieving HERE tokens, which you can then provide to the HERE OLP SDK for C++ libraries.
+1. Using your **platform credentials** that are available on the platform portal by means of the HERE OLP SDK for TypeScript authentication library.
+2. Using the **access key ID** and **access key secret** from the platform credentials as described in the [Authentication and Authorization Developer's Guide](https://developer.here.com/olp/documentation/access_control/topics/introduction.html) to create your own authentication and authorization client for retrieving HERE tokens that you can then provide to the HERE OLP SDK for C++ libraries.
 
-To obtain your platform credentials, create a new application via the [Apps and Keys](https://platform.here.com/profile/apps-and-keys) page. Then click **Create a key** to download these credentials. For more information on obtaining platform credentials, see the [Manage Apps](https://developer.here.com/olp/documentation/access-control/user-guide/topics/manage-apps.html) section of the [Teams and Permissions User Guide](https://developer.here.com/olp/documentation/access-control/user-guide/index.html).
