What is Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) is a security process that requires users to provide two distinct forms of verification before accessing an account.

Expanded Explanation

2FA enhances security by combining something the user knows (like a password) with something the user has (like a mobile phone or security token). It significantly reduces the risk of unauthorized access due to stolen credentials and is widely adopted across financial, enterprise, and cloud platforms.
