2FA (Two-Factor Authentication)

Two-Factor Authentication (2FA) strengthens account security by requiring users to verify their identity using two different methods. Usually, this combines something the user knows, like a password, with a second factor, such as a code sent to a mobile device, an authentication app, or biometric data like fingerprints. This dual verification process helps prevent unauthorized access even if a password is compromised.

2FA is commonly used in online services such as banking, email, and social media platforms to protect sensitive data. By adding this extra step, 2FA significantly improves overall account safety and user trust.
