two-factor authentication

Two-factor authentication (2FA) enhances security by requiring two forms of verification before granting access to an account. Typically, this involves something you know (like a password) and something you have (such as a smartphone app or a text message with a code). Even if someone gains access to your password, they still need the second factor to log in. This extra layer makes it much harder for unauthorized users to access your sensitive information, providing greater protection against hacking and identity theft.
