What is 2FA?

  • Dark

2FA stands for "Two-Factor Authentication." It is a type of multi-factor authentication (MFA) that involves using two methods to verify the identity of a user. 2FA is often used to protect online accounts and systems against unauthorized access.

2FA typically involves the use of two factors to authenticate a user's identity. These factors can include something the user knows (such as a password or a PIN), something the user has (such as a security token or a smartphone), or something the user is (such as a fingerprint or a facial recognition).

The use of two factors helps to ensure that the user is who they claim to be, because an attacker would need to have access to multiple pieces of information in order to gain access to the system. This makes 2FA more secure than traditional single-factor authentication, which only requires a single piece of information (such as a password) to authenticate a user's identity.

2FA is used in a variety of settings, including online banking, online shopping, and corporate IT systems. It is an effective way to protect against identity theft and other forms of cybercrime.
