# Configuring end user browsers

To support Kerberos authentication, you must add two trusted URIs to end user browsers.

The purpose of two URIs is future proofing. Ping Identity will migrate its infrastructure in the coming months. Adding the second URI ensures that your configuration will continue to work after the migration.

## Custom domains

If the environment is configured with a custom domain, `auth.pingone.com` and `kerberos.pingone.com` are irrelevant. Instead, add the custom domain as the trusted URI.

## Browser URI reference

When configuring end user browsers, use the following trusted URI values for the various PingOne geographies:

| Geography                                                                   | URI 1               | URI 2                   |
