Two-factor authentication or 2FA is a method of verifying a user’s claimed identity by using a combination of two different constituents. 2FA is a type of multi-factor authentication.
One of the best examples from everyday life is withdrawing money from ATM; only exact combination of a bank card (something that the user has) and a PIN (personal identification number, something that the user already knows) allows the transaction to be taken place.

Two factor authentication works with two different security or validation methods. In general, one is a physical confirmation token, and one is a rational password or code. Both must be confirmed before going through a secured service or product. By and large, an authenticating process needs a physical token or identity verification, followed by a rational password or personal identification number (PIN).
Two-factor authentication is one of the best methods to look after against remote attacks like phishing, credential misuse and other efforts to invade your accounts.
Without your physical device, distant attackers cannot claim to be you in order to get unofficial access to financial information, corporate networks, cloud storage, etc.
Login information is more important than ever, as organizations take on more remote workers and web-based applications. By incorporating two-factor authentication with these applications, attackers are not able to access your accounts without having your physical device required to fulfill the second factor.
