The <info>%command.name%</info> command generates a simple custom authenticator
class based off the example provided in:

<href=https://symfony.com/doc/current/security/custom_authenticator.html>https://symfony.com/doc/current/security/custom_authenticator.html</>

This will also update your <info>security.yaml</info> for the new custom authenticator.

<info>php %command.full_name%</info>
