What should I do if I receive a login Security Code but I wasn't logging in?

With 2-Step Authentication, the Security Codes we send you are a security feature. They can alert you if someone else is trying to log in as you. One thing to know is that if you use a third party service to access your banking information, it's likely that the service will get blocked during login. For each attempt made by that third party, a Security Code will be sent to you. You might want to disable your third party service or change your Banking PIN.
