MainStay Portfolio Login
Your online security is always a top priority. Due to that we have just implemented a new security service to further protect your account from unauthorized access.
In order to access your account you will be asked to complete a one-time personal security profile in which you will select a personal security image and image caption. You will also answer three security questions.
Each time you login, your security image and image caption will be displayed. When you see them, you will know that you can safely enter your password and that you have accessed the MainStay Investments website.
