To help keep your account secure, your single-use code will expire after a specific amount of time. Your code will expire after 15 minutes if it was sent via email or 5 minutes if it was sent via text message. This is to make it harder for an unauthorized user to access your account without your consent.
First, make sure you are only entering the most recent code that was sent. Each time you restart the login process or request a new code, all previous codes become invalid.
If your code is still arriving too late, please call our web support team at (800) 711-5672 for help.
