## Multi-Factor Authentication

Multi-Factor Authentication is a security system that requires users to provide two or more verification factors to gain access to a resource, such as a trading account or a crypto wallet. These factors typically include something the user knows, such as a password, something the user has, like a hardware token, and something the user is, such as a biometric trait.

In the context of financial derivatives and cryptocurrency, this adds a vital layer of defense against unauthorized access resulting from phishing or password theft. By requiring multiple independent channels of authentication, the system significantly reduces the probability of a successful breach.

Even if one factor is compromised, the attacker still cannot gain entry without the additional factors. This is particularly important for high-leverage accounts where rapid, unauthorized trading could lead to significant financial losses.

Modern implementations often utilize time-based one-time passwords or push-based notifications to streamline the user experience while maintaining high security. It is considered a baseline requirement for any professional-grade digital asset platform.

This practice reinforces the overall security posture of the financial ecosystem.
