This page describes how to enable Identity-Aware Proxy (IAP) for
a Google Cloud resource, using a Google-managed
OAuth client.
When enabling IAP on a resource using a Google-managed
OAuth client, only users within the organization in which the resource is
contained can access that resource. If you want to allow users outside of
the organization access to an IAP-enabled resource, enable
custom OAuth credentials.
Enable IAP for a new resource
New Google Cloud resources don't have IAP enabled.
Complete the following steps to enable IAP on a new resource.
In the list of resources, go to the settings of the resource for which you
want to configure custom OAuth credentials.
Select the Enable custom OAuth credentials to allow users outside of this
organization to access this application checkbox.
In the OAuth configuration dialog, enter a client ID and secret.
Optional: To have a client ID and secret generated for you, click
Auto generate credentials.
You can download the client credentials to a CSV file, or delete the
credentials. After you save your changes, custom client credentials cannot
be retrieved, so we recommend that you save your credentials.
If you delete the credentials, the auto-generated OAuth client
is also deleted.
To save your changes, Click Save. Saving your changes does not change
the IAP enabled state.
Change to a Google-managed OAuth client
You can change resources using a custom OAuth client to use a Google-managed
OAuth client by completing the following steps.
