Two-Factor Authentication Security

Two-Factor Authentication (2FA) security is the implementation of an additional layer of protection beyond a password. In cryptocurrency, this usually involves time-based one-time passwords (TOTP) or hardware security keys like YubiKeys.

While 2FA significantly improves account security, it is not infallible against advanced phishing attacks that can intercept real-time codes. Using hardware-based 2FA is generally safer than SMS-based 2FA, which is susceptible to SIM swapping attacks.

Strengthening 2FA is a key component of a robust security posture for any digital asset trader.
