2FA

Two-factor authentication is an electronic authentication method that adds an extra layer of security to online accounts by verifying a user's identity using two components, typically something they know and something they have.

It works by verifying the user's identity using two components: something the user knows (e.g., a password) and something the user has (e.g., a mobile phone or a security token).

2FA is an extra layer of security used to make sure that people trying to gain access to an online account are who they say they are. First, a user enters their username and password. Then, instead of immediately gaining access, they will be required to provide another piece of information, usually called an 'authentication factor'.

This is important because it adds a layer of security that can help protect the user's account even if their password is compromised. While 2FA is commonly used to protect personal accounts like email and social media, it is also used in enterprise environments to protect sensitive data and systems.
