2FA or Two-Factor Authentication is an extra step of security for Cryptal accounts and it is created to ensure that the account owner is the only person who can access their account, even if someone knows their password. When signing into your account, you will be asked to provide your password and an authentication code generated every thirty seconds by an authentication app. We strongly recommend activating 2FA as it offers a higher level of security than default SMS verification and prevents unauthorized access to your accounts.
