Assume anyone asking for your account information for any reason is guilty of scamming you, unless proven innocent. The way to prove innocence is to call them back, or login to your account using numbers or a website that you provide, not them. Don’t release any identifying information while they are contacting you via phone, message or email. You must control the channel.
The best way to measure your investing success is not by whether you're beating the market but by whether you've put in place a financial plan and a behavioral discipline that are likely to get you where you want to go.
