Two-Factor Authentication (2FA) adds an extra layer of security to online accounts, including those used for managing cryptocurrency. It requires two forms of verification before granting access. The first factor is typically something the user knows, like a password. The second factor is something the user possesses, such as a mobile device or a hardware token. When logging in, the user enters their password and then receives a code via text, email, or an authentication app, which must be input to complete the login process.This method significantly enhances security. Even if someone manages to steal a password, they would still need the second factor to gain access. This is especially important in cryptocurrency, where unauthorized access can lead to loss of funds. Implementing 2FA helps protect accounts from scams and hacking attempts, making it a standard practice for anyone serious about safeguarding their digital assets. Overall, 2FA is a straightforward yet highly effective security measure.
