Set up Two Factor Authorization (2FA) with your bank or brokerage account. The process where your identity is fully verified before any money leave your account.
You may not know it, but you probably already use two-factor authentication in the physical world
"two-factor authentication is a simple feature that asks for more than just your password. It requires both "something you know" (like a password) and "something you have" (like your phone). Think of it as entering a PIN number, then getting a retina scan, like you see in every spy movie ever made. It's a lot more secure than a password (which is very hackable)"
