## Two-Factor Authentication

Two-factor authentication is a security process that requires users to provide two different forms of identification to access their trading accounts or wallets. Typically, this involves something the user knows, such as a password, and something the user has, such as a time-based one-time password generated by an application or a hardware security key.

By requiring a second factor, this method significantly reduces the risk of unauthorized access resulting from compromised passwords or phishing attacks. In the context of digital assets, it is considered a baseline requirement for protecting account integrity.

It adds a layer of defense against remote account takeovers, ensuring that even if credentials are stolen, the attacker cannot easily gain control. Consistent use of this protocol is a primary pillar of individual trade safety.
