2FA

Two-Factor Authentication (2FA) enhances the security of cryptocurrency accounts by requiring two independent credentials: typically something the user knows (password) and something the user has (a code from an authenticator app or SMS). This added security layer helps protect accounts from unauthorised access, especially in the volatile crypto industry where hacks and phishing attacks are common. Popular authenticator apps include Google Authenticator and Authy, generating time-based codes that refresh every 30 seconds. Unlike SMS-based 2FA, app-based methods are more secure, as they are less susceptible to SIM swapping attacks. Most crypto exchanges and wallets now offer 2FA, making it an essential step for anyone managing digital assets.
