2FA (two-factor authentication) is an essential tool for protecting digital assets, combining passwords with a second layer of identification (such as one-time codes, biometrics, etc.) to enhance account security. Nowadays, especially for Crypto Assets and financial accounts, enabling 2FA has become an industry standard to prevent account theft. Setting up 2FA includes choosing an authentication method, linking tools, and saving recovery codes, and it is recommended to enable and regularly update it on all important accounts to ensure security.
