# Manage pass-through authenticator policies

Use this page to select which pass-through authenticator definition is active for pass-through authentication. The selected definition controls which connector request and response logic is used when IDaaS evaluates pass-through authenticator challenges.

note

Before configuring a pass-through authenticator policy, create a [pass-through authenticator definition](/docs/authentication-and-security/manage-authenticators/manage-pass-through-authenticators/create-pass-through-authenticator-definitions.md).

## Configure pass-through authenticator policy

1. Click Menu icon **>** **Policies > Authenticators**. The **Authenticators** page appears.
2. Select **Pass-through Authenticator**. The **Pass-through Authenticator** page appears.
3. From the **Pass-through Authenticator Definition** drop-down list, select the pass-through authenticator definition to use for API authentication.
4. Click **Save**.

## Validate your changes

After you save, verify the following:

1. The selected definition remains displayed after page refresh.
2. Authentication flows that use pass-through authenticators call the expected external service behavior.
3. Valid test requests succeed and invalid test requests fail based on the selected definition.
