Two-Factor Authentication (2FA)
Table of contents
Two-Factor Authentication (2FA) is a security method that requires users to provide two forms of identification before gaining access to an account or system.
How 2FA Works
2FA adds an extra layer of protection beyond just a password. After entering the password, users are prompted to provide a second factor, typically a one-time code sent to their phone or generated by an authenticator app. This process helps prevent unauthorized access, even if a password is compromised.
Why 2FA Matters
2FA is crucial in protecting sensitive data and accounts, such as cryptocurrency wallets or online banking. It greatly reduces the risk of hacking by ensuring that an attacker would need both the password and access to the second factor (e.g., a phone) to gain entry.
