Ensure you are entering your personal information exactly as it was entered during Registration. MFA activation only needs to be completed once for each new Secure Website Account, unless you are setting up a new MFA device or you need to reset your MFA token. Ensure you have received the registration confirmation email before activating MFA; you must have an active and valid RDS Secure Website account prior to activating or managing MFA.
Refer to Multi-Factor Authentication for additional information.
