Two-Factor Authentication (2FA) is an essential security measure that requires users to provide two distinct forms of identification before gaining access to an account. After entering a password, users must also input a verification code sent via SMS or generated by an app, adding a crucial second layer of security. This process ensures that even if a password is compromised, unauthorized users cannot access the account without the additional code. Multi-Factor Authentication (MFA) further strengthens this protection by introducing multiple verification methods, making accounts even more secure.
