1: Enable Two-Factor Authentication (2FA)on all platforms where you store valuable assets or personal information.
I'm just wondering, don't all exchanges require users to have 2FA? Without 2FA, an account is like an open cookie jar for hackers. But since it was mentioned in the OP, I'm curious. Most exchanges I use force me to enable 2FA, and sometimes I even get an email confirmation when I transfer coins.
Can the 2FA protects our funds in the centralized exchanges?
I think the answer is no.
The best thing is to avoid the centralized exchanges for saving purposes, we should rather use them as market place where we can buy and sell our cryptocurrencies, and then save them in our personal wallets where we will have the control of the private key.
However, the use of 2FA in our personal wallets can be very important, but the must important thing is to secure our private keys to avoid losing your money.
