### Client Certificate Selection

Some websites require you to identify yourself with a certificate. The option you select here determines how Navigator identifies the certificate to present among those you may have on file:

- Select Automatically: Click this option if you want Navigator to select a certificate without asking you. This is the default setting.
- Ask Every Time: Click this option if you want Navigator to ask you which certificate to use each time a website requests one.

### Manage Certificates

Certificates are the digital equivalent of ID cards—they help other people identify you, and they help you identify other people, websites, and organizations.

To examine or configure the certificates you have on file, click Manage Certificates.

### Manage Security Devices

A security device is a hardware or software device that stores your certificates and keys. For example, a smart card is a security device. Your browser has its own built-in software security device, and you can use additional security devices, such as smart cards, at the same time.

To examine or configure your security devices, click Manage Security Devices.
