Crypto exchanges ( Kraken, Binance etc).Social media (Instagram, Facebook, Twitter etc).Here are a few popular sites to use 2FA on: I would use 2FA whenever it is possible, but I especially highly suggest using it on websites that contain sensitive information that can be used by a hacker to damage you or steal assets. This ensures that if someone guesses or cracks your password, they still won’t be able to login unless they are also successful in robbing your physical 2FA device. Most banks give out a 2FA device or card which stores some codes you are required to enter when logging in.


Most of you will already have used 2FA, perhaps without knowing so, when you log in to your internet banking. Two-factor authentication or 2FA is a way of making your logins more secure, by not only requiring a username and password when signing in, but also a special extra code that can either be received as an SMS or else generated by an app or device.
