## Multi Factor Authentication

Multi-factor authentication is a security process that requires users to provide two or more verification factors to gain access to an account. In the crypto space, this typically involves a password combined with a time-based one-time password from an app or a physical security key.

This adds a vital layer of protection against unauthorized access if a password is compromised. It is a standard requirement for all reputable exchanges and financial platforms.

While not a replacement for strong key management, it significantly raises the bar for attackers. For traders, it is a non-negotiable component of account security, protecting against everything from simple phishing to sophisticated credential stuffing attacks.
