What is two factor authentication (2FA)?

Two factor authentication (aka 2FA) is a second layer of security for your account. If you select this option, after login you will be asked to provide a code that is generated by your tablet or smartphone app, valid only for 30 seconds. Any app using the TOTP algorithm can work with our website (e.g Google Authenticator, Authy, 1Password, Lastpass…). This method of signing in to websites relies on something you know and something in your possession. That is why it is referred to as two-factor – because two factors are involved in authenticating you. While 2FA does improve security, it is not foolproof.

If you want to know more about 2FA you can read the Wikipedia page here or the Investopedia page here.
