Describe the problem you'd like to have solved

v5 appears to have removed the hooks mentioned in this issue. I am using pantheon, and need to prefix the cookie names with STYXKEY_ to avoid cookies being lost due to the CDN.

Describe the ideal solution

The ideal solution would be to add an optional field to the plugin's settings in the WordPress admin dashboard to set the SDK configuration object's storage IDs with the prefix. This would save custom work needing to be done to achieve this with the plugin.

Alternatives and current workarounds

I achieved a workaround by adding a plugins_loaded action in functions.php of my site as follows:

// change the auth0 cookie name to be prefixed with STYXKEY_ for Pantheon
function update_auth0_cookie_storage_id()
{
  $auth0SDK = wpAuth0()->getSdk();
  $auth0Config = $auth0SDK->configuration();
  $storageId = 'STYXKEY_' . $auth0Config->getSessionStorageId();
  $transientId = 'STYXKEY_' . $auth0Config->getTransientStorageId();
  $auth0Config->setSessionStorageId($storageId);
  $auth0Config->setTransientStorageId($transientId);
  $auth0Config->setSessionStorage(new CookieStore($auth0Config, $auth0Config->getSessionStorageId()));
  $auth0Config->setTransientStorage(new CookieStore($auth0Config, $auth0Config->getTransientStorageId()));
  $auth0SDK->setConfiguration($auth0Config);
}
add_action('plugins_loaded', update_auth0_cookie_storage_id());

I was able to update the configuration of the SDK by using this method. However, it took me a while of reading the source code of the plugin and SDK to find this solution, so I am proposing adding a setting in the Plugin settings on the WordPress admin dashboard.

Hey @jaketfoster, thanks very much for the suggestion. My bandwidth is currently allocated to another project so I can't give a firm ETA, but we will get to this as soon as possible. In the meantime, your workaround solution looks excellent 👌
