What is Two Factor Authentication (2FA) ?


Two-factor authentication (2FA) is a security process in which a user provides two different authentication factors to verify their identity. This helps to ensure that the user is who they claim to be and helps to prevent unauthorized access to the user's account.

There are several different types of authentication factors that can be used for 2FA, including something the user knows (such as a password or PIN), something the user has (such as a security token or a mobile phone), and something the user is (such as a fingerprint or facial recognition).

You should use 2FA to help protect your accounts from unauthorized access. It is an extra layer of security that can help to prevent someone from gaining access to your accounts, even if they have your password. This is especially important for accounts that contain sensitive or personal information, such as financial accounts or email accounts.

Using 2FA can also help to protect you from phishing attacks, where an attacker tries to trick you into giving them your login credentials by pretending to be a legitimate website or service. By requiring a second form of authentication, 2FA makes it more difficult for attackers to gain access to your accounts.
