Cryptocurrency exchanges are websites where you can exchange one form of cryptocurrency for another. You can send your cryptocurrency to a “hot wallet” on the exchange in order to trade one crypto for another. It is recommended strongly that once you make the trade, you move your new currency into a hardware, computer or mobile wallet. This will ensure that if the exchange gets hacked, your crypto will be safe on your own system.
2FA, also known as two-factor authentication, is extremely important in using cryptocurrency exchanges. This essentially connects the device you are using to do a trade to another device you own for withdrawls and transfers. If your device were to be hacked and you have 2FA, say to your mobile device, the hacker would not be able to move any of your money unless they also had access to your phone.
Google Authenticator is a great app used for cryptocurrency 2FA. It sends a new 6 digit code to your phone on a timed basis, which then needs to be put in at the exchange. Many exchanges will not require 2FA, but it is seriously encouraged.
