U.S. shared Short Codes - what happens when an end user replies 'HELP'?

Our shared Short Codes in the U.S. are configured to immediately answer end users who test 'HELP' into them. An outbound message will be sent back, indicating:

"You recently created or modified an account online. Enter your passcode to confirm. Email for 2-factor authentication support."

This message is sent in order to meet US carrier compliance requirements.
