  • Why do I need cookies to log in to Fidelity?
    Without cookies, your browser would be unable to remember that you were logged in, and you'd have to reenter your SSN or username and password for every page you viewed. For more information about how Fidelity uses cookies, see our Privacy Policy.
  • What are Extended Validation Certificates?
    Fidelity uses Extended Validation (EV) Certificates as an additional security measure. EV Certificates are issued to websites only after rigorous validation of their identity. Web browsers reflect this higher level of identity assurance with prominent and distinct trust indicators, such as the green address bar in Internet Explorer and Mozilla Firefox, and advanced green indicators in the latest versions of Opera and Google Chrome.
