| 2          | Admin: Configure Device Agent for Device Verification               | **Windows:** [Windows: Configure Device Agent settings](/docs/authentication-and-security/manage-device-verification/configure-device-agent-on-windows/windows-configure-device-agent-for-device-verification.md) **MacOS:** [MacOS: Configure Device Agent settings](/docs/authentication-and-security/manage-device-verification/configure-device-agent-on-apple-macintosh/macos-configure-device-agent-for-device-verification.md)                                                                                                                                                                                                                              |
| 3          | Admin: Configure a Certificate Authority                            | See [Manage Certificate Authorities](/docs/authentication-and-security/manage-certificate-authorities.md). If you are using a Microsoft Certificate Authority, you must [Create and configure a gateway](/docs/gateways/create-and-configure-a-gateway.md) and [add a directory](/docs/directories-and-provisioning/manage-directories.md). If you are using an Entrust Managed PKI CA, creating a Gateway and adding a directory is optional.                                                                                                                                                                                                                     |
| 4          | Admin: Generate and install the computer certificate                | After configuring the CA, the administrator must generate and install a certificate on the computer that requires access. The administrator must generate a certificate for each computer to be supported. Depending on the Operating System, follow the corresponding specifications: [Windows: Configure certificates and CAs](/docs/authentication-and-security/manage-device-verification/configure-device-agent-on-windows/windows-configure-certificates-and-cas.md) [MacOS: Configure certificates and CAs](/docs/authentication-and-security/manage-device-verification/configure-device-agent-on-apple-macintosh/macos-configure-certificates-and-cas.md) |
| 5          | Admin: Configure a resource rule to support Device Verification.    | See [Create and manage resource rules](/docs/authentication-and-security/create-and-manage-resource-rules.md).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     |
| 6          | Test login to Identity as a Service through the supported browsers. | The user should be able to login to Identity as a Service using Device Verification. See the [System Requirements](/docs/get-started/requirements.md) for a list of supported browsers.                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
