When registering my device in CardValet I did not receive the security token even though a message displayed stating that the token was sent.

If you did not receive the security token, you should check your spam or junk folder. The email is from Elastic Email On Behalf Of SouthPoint. The one time registration password is forwarded to the email address that is on the cardholder record. The one-time Forgot Password security token is sent to the email address that the user entered when registering in CardValet.
