Two-factor authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity before gaining access to an online account or system. This additional layer of security helps to protect against unauthorized access, even if a password is compromised.

In a typical 2FA setup, the first factor is usually something the user knows, such as a password or PIN, while the second factor is something the user possesses, like a mobile device or security token. By requiring both factors, 2FA significantly enhances the security of online accounts and helps prevent unauthorized access, data breaches, and identity theft.

Implementing two-factor authentication is considered a best practice for securing online accounts and is widely used by businesses, websites, and online services to protect sensitive information and user data.
